Our innovative timber wind power towers are not only leading in terms of technology, but also blaze new paths with their ecological and economical balance sheet. We source our raw material wood from regional sources and additionally offer the possibility to source the wood directly from the wind power system\u2019s location and feeding it into the HASSLACHER group\u2019s delivery chain. If the wood meets the requirements, we can use it to built your wind turbine tower. This minimises truck journeys and reduces the associated carbon emissions. Every log is photographed and and integrated into our (quality assurance) system.<\/p>\n<p>This way, we ensure maximum transparency in the (quality assurance) system and in raw material processing. Once the wind tower has reachedthe end of its useful life cycle, we offer options to buy back the wood, if the customer wishes. The wood can then be used on the next structural timber solution. This way, we complete the material cycle and promote the sustainable use of resources. At the moment, our production capacities allow for an output of 100 towers annually, based on a hub height of approx. 160 m. Thus, HASSLACHER Green Tower GmbH sets new standards in wind power technology by combining sustainability with efficiency.<\/p>\n<\/div>\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-block-spacer-block_a4404840fe53c88bcb7ac32712620285\" class=\"ep-block-spacer ep-block \">\n            <div id=\"The timber hybrid tower\" class=\"show-frontend\">\n                        <style>\n                #ep-spacer-C9dX7 {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-C9dX7 {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-C9dX7 {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-C9dX7\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-title-block_3c77d0c2785af5025c14c395558dd9f6\" class=\"ep-title ep-block \">\n        <div class=\"show-frontend\">\n        <div class=\"inner alignment-left style-normal\">\n\n                            <h2 class=\"title\">\n                    <span class=\"text\">\n                        The timber hybrid tower\n                        <span class=\"space-wrapper\"><span><\/span><\/span>\n                    <\/span>\n                                    <\/h2>\n\n            \n\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-two-cols-text-block_834a3c6e9ce9054c15b0f80aba831c10\" class=\"ep-two-cols-text ep-block \">\n            <div class=\"show-frontend\">\n            <div class=\"inner\">\n                                    <div class=\"text text-type-left\"><p>HASSLACHER Green Tower GmbH\u2019s timber hybrid tower for wind power systems is a resolved spatial timber frame structure using glued laminated timber beams made from spruce using a hybrid construction method (wood-metal composite). In the framework of the timber hybrid construction method the respective materials are used in such a way that their specific strength is optimally applied, resulting in great value for money for our customers. Our tower concept is based on four timber supports with diagonals made from laminated beams and tip consisting of a conventional steel tube structure. Our hybrid towers are structures that are freely exposed to the elements, showing off the wood they are made.<\/p>\n<p>Contrary to most conventional wind power systems, our timber hybrid towers are not founded on circular flat foundations, but on four relatively small individual foundations that only protrude out of the ground at the supports. Compared to circular flat foundations, the individual foundations use 50% less cement, sand, gravel and reinforcing steel.<\/p>\n<\/div>\n                                                    <div class=\"text text-type-right\"><p>Additionally, their significantly lower volume markedly reduces construction time and has the benefit that, once they have reached the end of their useful life, the foundations can be removed without a trace easily and cheaply.<\/p>\n<p>The entire construction is maximally pre-fabricated and produced with a high degree of automation, where the pre-assembled elements can be installed easily and quickly, regardless of the weather. Maintenance lift, ladder, power and control cables are run centrally through the frame, permanently protected from all weather by a \u201ctower within a tower\u201d and run all the way to their transition into the steel tube tower. HASSLACHER Green Tower\u2019s timber hybrid towers fulfil all structural, dynamic and requirements resulting from operation. T\u00dcV Nord\u2019s certification is a generic type certification that allows for the construction of the timber hybrid structure in all climate zones of Europe. For the future, we are planning to acquire component certification for our tower, to make sure that new certifications can be processed even more quickly and efficiently.<\/p>\n<\/div>\n

A high degree of prefabrication and exclusively mechanical joints allow for simple and quick assembly, almost independent of the weather.<\/p>\n                                                            <\/div>\n                        \n                            <div class=\"cta\">\n        \n        \n                                    <a href=\"https:\/\/www.hasslacher-greentower.com\/en\/thinking-about-the-future\/\" title=\"Increased future thinking\" target=\"\" class=\"btn white\">\n            <span>Increased future thinking<\/span>\n        <\/a>\n    <\/div>\n                    <\/div>\n                <\/div>\n                \n            <\/div>\n\n        <\/div>\n    <\/div>\n\n<div id=\"ep-block-spacer-block_2bac2f1cb4b69f0da9694d357235fd71\" class=\"ep-block-spacer ep-block \">\n            <div  class=\"show-frontend\">\n                        <style>\n                #ep-spacer-IbwEu {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-IbwEu {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-IbwEu {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-IbwEu\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-title-block_7ac228cb605b6b0d241727b2dde8e28a\" class=\"ep-title ep-block \">\n        <div class=\"show-frontend\">\n        <div class=\"inner alignment-left style-normal\">\n\n                            <h2 class=\"title\">\n                    <span class=\"text\">\n                        Flexible from root to top!\n                        <span class=\"space-wrapper\"><span><\/span><\/span>\n                    <\/span>\n                                    <\/h2>\n\n            \n\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-two-cols-text-block_4417f8df30117974eaffddc8c418a6bd\" class=\"ep-two-cols-text ep-block \">\n            <div class=\"show-frontend\">\n            <div class=\"inner\">\n                                    <div class=\"text text-type-left\"><p>Thanks to 10 years of development, HASSLACHER Green Tower GmbH\u2019s construction delivers maximum efficiency and thus, an attractive purchase price. Intelligent wood protection measures result in low maintenance costs. At the end of its useful life, the wood has a material value exceeding the costs of its removal, leading to positive removal earnings. Low removal provisions for the counties lower capital commitments. Wood as a renewable raw material has stable purchase prices and has no CO<sub>2<\/sub> pricing compared to steel and reinforced concrete. Simply through removing the connecting material in the timber structure and the time-saving cutting of the relatively small individual foundations, customers only accrue low removal costs. Parametrising all contributing factors can reduce the certification time for new systems.<\/p>\n<\/div>\n                                                    <div class=\"text text-type-right\"><p>Component certification can help transfer type certificates to other systems without excessive work and time. Hybrid towers are also flexible to assemble in terms of the weather conditions. Since the system doesn\u2019t use glue joints, but only metal-to-metal joints at the construction site, the towers can be assembled regardless of the weather. The timber hybrid tower can even be used in complex site conditions. Its benefits lie in the scalability of the timber elements and their lower weight. This allows the timber tower elements to be brought to the wind power system\u2019s location through lower corner radii, reducing the effect on the site. Small-format individual foundations allow for the entire wind power system to be removed easily and without leaving a trace behind.<\/p>\n<\/div>\n                            <\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-block-spacer-block_2bac2f1cb4b69f0da9694d357235fd71\" class=\"ep-block-spacer ep-block \">\n            <div  class=\"show-frontend\">\n                        <style>\n                #ep-spacer-njQCh {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-njQCh {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-njQCh {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-njQCh\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-splash-block_9cc9f2a2d7c798af544f7780897eb1da\" class=\"ep-splash ep-block \">\n            <div class=\"show-frontend\">\n\n            <div class=\"inner type-2  \">\n                <div class=\"text-wrapper\">\n                    <div class=\"text-wrapper-inner\">\n\n                        \n                                                    \n                            <h3 class=\"title\">We are here to assist you!<\/h3>\n                        \n                                                    <div class=\"space-wrapper\"><span><\/span><\/div>\n                        \n                        \n                            <div class=\"cta\">\n        \n        \n                                    <a href=\"https:\/\/www.hasslacher-greentower.com\/en\/contact-us\/\" title=\"Get in touch now!\" target=\"\" class=\"btn white\">\n            <span>Get in touch now!<\/span>\n        <\/a>\n    <\/div>\n                    <\/div>\n                <\/div>\n                \n            <\/div>\n\n        <\/div>\n    <\/div>\n\n<div id=\"ep-block-spacer-block_2bac2f1cb4b69f0da9694d357235fd71\" class=\"ep-block-spacer ep-block \">\n            <div  class=\"show-frontend\">\n                        <style>\n                #ep-spacer-D9Zlm {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-D9Zlm {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-D9Zlm {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-D9Zlm\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-title-block_3d5de9a7060fc080ab1d526411216cba\" class=\"ep-title ep-block \">\n        <div class=\"show-frontend\">\n        <div class=\"inner alignment-left style-normal\">\n\n                            <h3 class=\"title\">\n                    <span class=\"text\">\n                        Do you have any questions about the construction of the HASSLACHER Green Tower?\n                        <span class=\"space-wrapper\"><span><\/span><\/span>\n                    <\/span>\n                                    <\/h3>\n\n            \n\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-accordion-block_5b64472574e1ecad9fefbfdec7eb2b88\" class=\"ep-accordion ep-block \">\n            <div class=\"show-frontend\">\n            <div class=\"inner\">\n                                                    <div class=\"accordion-wrapper\">\n                        <div class=\"accordion-items\">\n                                                            <div class=\"accordion-item active\">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">What are the properties of the timber hybrid tower&#8217;s construction? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>The HASSLACHER Green Tower timber hybrid tower is an open timber frame structure made from glued laminated timber (glulam), meaning it\u2019s a rod-shaped structure. Glued laminated timber consists of wooden layers bonded in the same grain. Such lamellas made from solid wood are mainly used in mass timber engineering, meaning structures subject to structural and dynamic loads. Glued laminated timber beams are also known as glulam trusses. The hybrid tower structure\u2019s lower part is made from four solid glulam supports connected by timber diagonals (also made from glulam beams). An adapter piece made from steel leads to the upper part of the structure, which consists of traditional steel tube sections with a maximum diameter of 4.3 m.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">How much of the entire system is made from wood?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Depending on the configuration, the wood portion of the timber hybrid tower comes in at approx. 90 volume percent of all materials used in the tower.

These individual foundations are designed to be relatively small, meaning that they save approx. 50% of concrete compared to the usual 1,000 m<sub>3<\/sub> of concrete used. The timber supports are connected to the four individual foundations via adapters that are pre-mounted in the factory. These four individual foundations consist of one base plate each and a plinth in the shape of a truncated pyramid. The anchor rods used to connect to the timber supports protrude out of those. The foundations are connected to an external earthing ring.<\/p>\n<p>We are currently working on implementing deep foundations (anchoring technology using pilots). This will further reduce the volume of concrete used significantly. Thus, the foundations will be even easier and faster to remove.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Why was a hybrid chosen for the first tower version?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Timber boasts excellent properties when it comes to loads in grain. Thus, a timber structure is very good at transferring tensile and compressive loads. Loads perpendicular to the grain as caused by torsional forces, however, present a significant challenge to timber as a construction material. Since these forces are often exceedingly large due to the wind power system\u2019s rotor blades, a hybrid tower was chosen as the first development stage. The reason for this is that steel is very well suited to transferring high torsional forces in the tower\u2019s head area thanks to its shear modulus. We are able to transfer the high torsional forces at the tower\u2019s foot through spreading out the structure.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Are you able to comment on the service life of the timber hybrid towers?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Our industrially bonded weathering layer made from pine heartwood is at least 4 cm thick and lasts 20 years, but can also be made thicker depending on the wind power system\u2019s life cycle. The fact that this weathering layer protects the load-bearing timer structure well, was proven in series of tests.<\/p>\n<p>When it comes to material fatigue, we are able to reference many tests done on the timber elements by material testing institutes. Comprehensive material fatigue tests have shown that timber initially shows fatigue tendencies similar to those of steel or concrete. Interestingly, however, timber virtually stops fatiguing after a certain period of time. This proven effect is shown in fatigue curves or so-called W\u00f6hler curves.<\/p>\n<p>This effect can be explained through the natural adhesives in the wood as well as the dynamic type of load transfer of the timber materials. This is why we assume that the timber structure will last significantly longer than 20 years. Furthermore, our timber structures are always designed in such a way that all \u201cpredetermined breaking points\u201d are located within the steel elements, meaning the timber structure\u2019s life cycle always exceeds that of the mechanical parts (both in terms of connecting means and the wind power system itself).<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Does the timber hybrid tower&#8217;s erection require bonding processes to be performed at the construction site?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Bonding processes for load-bearing timber elements must be performed under controlled conditions (meaning in a factory hall) and may only be done by certified companies. Critical weather conditions such as exceedingly low temperatures or high humidity, but also dust particles, can compromise the quality of the bonded joints to the point where their structural integrity can no longer be guaranteed. Thanks to the high rental costs for tall cranes, wind power towers must be erected in a minimum number of days. This does not leave time for the two-component adhesive to cure in a closely timed assembly process. Furthermore, possible bonding defects can no longer be corrected once the elements are installed at the construction site. This is why we only use mechanical connections at the construction site. This has the further benefit that assembly crews that specialise in timber construction are not required.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                    <\/div>\n                    <\/div>\n                            <\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-block-spacer-block_2bac2f1cb4b69f0da9694d357235fd71\" class=\"ep-block-spacer ep-block \">\n            <div  class=\"show-frontend\">\n                        <style>\n                #ep-spacer-u4KE3 {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-u4KE3 {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-u4KE3 {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-u4KE3\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-title-block_7f44777e4113cb0fa49ecddc4c45d5c7\" class=\"ep-title ep-block \">\n        <div class=\"show-frontend\">\n        <div class=\"inner alignment-left style-normal\">\n\n                            <h3 class=\"title\">\n                    <span class=\"text\">\n                        Do you have questions regarding the technology used on the HASSLACHER Green Tower timber hybrid tower?\n                        <span class=\"space-wrapper\"><span><\/span><\/span>\n                    <\/span>\n                                    <\/h3>\n\n            \n\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-accordion-block_533a9a743acf49fdd0a6d7d8531ffb88\" class=\"ep-accordion ep-block \">\n            <div class=\"show-frontend\">\n            <div class=\"inner\">\n                                                    <div class=\"accordion-wrapper\">\n                        <div class=\"accordion-items\">\n                                                            <div class=\"accordion-item active\">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Where are the electrical components (transformer, inverter, switch cabinets etc.) of the wind power system installed?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>The open timber frame structure leaves much more room to install electrical components in the tower\u2019s foot and inside the tower\u2019s structure than with any other tower construction method.

Visually, a technical equipment station made from wood fits a timber tower better than possible containers made from steel or concrete.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                    <\/div>\n                    <\/div>\n                            <\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-block-spacer-block_2bac2f1cb4b69f0da9694d357235fd71\" class=\"ep-block-spacer ep-block \">\n            <div  class=\"show-frontend\">\n                        <style>\n                #ep-spacer-tPF2u {\n                    height: 100px;\n                }\n\n                @media (max-width: 767px) {\n                    #ep-spacer-tPF2u {\n                        height: 40px;\n                    }\n                }\n\n                @media (min-width: 768px) and (max-width: 1023px) {\n                    #ep-spacer-tPF2u {\n                        height: 60px;\n                    }\n                }\n            <\/style>\n            <div id=\"ep-spacer-tPF2u\"><\/div>\n        <\/div>\n    <\/div>\n\n<div id=\"ep-title-block_db456f4e4783b0df81f90f113fd4f737\" class=\"ep-title ep-block \">\n        <div class=\"show-frontend\">\n        <div class=\"inner alignment-left style-normal\">\n\n                            <h3 class=\"title\">\n                    <span class=\"text\">\n                        Do you have questions regarding the logistics\/assembly of the HASSLACHER Green Tower timber hybrid tower?\n                        <span class=\"space-wrapper\"><span><\/span><\/span>\n                    <\/span>\n                                    <\/h3>\n\n            \n\n            \n        <\/div>\n    <\/div>\n<\/div>\n\n<div id=\"ep-accordion-block_947778ea5c706cf5bf201aaf904d5995\" class=\"ep-accordion ep-block \">\n            <div class=\"show-frontend\">\n            <div class=\"inner\">\n                                                    <div class=\"accordion-wrapper\">\n                        <div class=\"accordion-items\">\n                                                            <div class=\"accordion-item active\">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Does the timber hybrid tower offer any benefits in terms of the accessibility of complex locations (segmentability)? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>The timber hybrid tower\u2019s structural elements can be segmented.

Such certification processes are very challenging. This is likely the reason that were are currently and so far (2023) the only company in the world that has received type certification for a timber tower structure. The timber hybrid tower (as Green Tower timber hybrid tower \u2013 T-7003\/22-1 Rev. 0) and the associated foundations (surface foundations without lift \u2013 T-7003\/22-2 Rev. 0) received type certification by the inspection office for structural design and wind power systems at T\u00dcV NORD CERT GmbH according to DIBt regulation. In this context the timber hybrid tower was certified with a VENSYS 126 (incl. Vers. 2), a hub height of 136.9 m and a nominal output of 3.8 MW. We furthermore possess type certification for a Vensys 120 (137 m, nominal output: 3.0 MW). Other certifications with other hub heights, tower versions and system manufacturers are pending.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">What happens when lightning hits the rotor blades \/ the timber hybrid tower? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>For this purpose, a round wire leading to an earthing ring that runs around the foundations is installed.

The massive diameter of the supports and diagonals prevents this oxygen delivery from three sides, meaning that only the side exposed to the fire would slightly char. Thanks to the density of the solid wood construction (glued laminated timber) and the associated protective carbon layer, the comparatively low heat conductivity of wood (cool core) and its limited oxygen supply, only a thin layer (several mm) of the surface would char before the fire would be go out automatically. The timber structure\u2019s structural integrity is therefore not substantially threatened by a fire.<br \/>\n<a href=\"https:\/\/www.hasslacher-greentower.com\/en\/fire-protection-for-timber-constructions\/\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\">Learn more &gt;<\/span><\/a><\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Did scientists accompany the timber hybrid tower&#8217;s development? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>The timber hybrid tower\u2019s development is not only based on 125 years of group experience, but also on many years of development.

In the course of this, the Technical University of Graz, the University of Stuttgart, the Technical University of Munich, the Technical University of Braunschweig and the RheinMain University were involved. Additionally, tests were undertaken at the material testing facility in Leipzig. Moreover, a number of specialised design offices were consulted for development work.

Its experience with production and quality assurance is accordingly vast.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">What precision is applied in the production of construction elements? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Cutting, planing and glued laminated timber production now exhibit an extremely high degree of precision when it comes to construction element production. Apart from a number of quality-assurance measures (see FAQs quality assurance) cutting, planing and joinery processes take place with a precision of +\/- a tenth of a mm (1\/10 mm). Moreover, all construction elements are once again 3D-measured by a laser unit and compared to the blueprints. Laser measurement is used across the entire assembly process, too, by the way. In the framework of the certification process, load cases must be calculated assuming a possible tilt of the wind power system. Such possible tilts exceed the internal tolerances in production by many factors.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">How is the quality of the processing of the natural resource that is wood assured? <\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Unlike synthetic materials like steel and concrete, wood, as a natural product, has inherent variations in density and strength. To ensure structural integrity, a high degree of material homogeneity must be achieved through careful selection and processing. In addition to the quality assurance measures in the cutting area, a range of quality-assuring measures follow in the glued laminated timber production facilities. For example, every single lamella that is used on a glued laminated beam to be used in a glued laminated timber structure is checked several times. Each lamella is exposed to defined tensile loads, x-rayed in the framework of an imaging process (e.g. to expose deep defects), electronically measured for their moisture content, and subsequently acoustically struck to determine the lamella\u2019s strength from the returning sound. For all analysed individual lamellas, a stiffness spread is created and only those lamellas that lie within a defined range are approved for production. Furthermore, the position of every single lamella inside the beam is defined on the basis of its strength and documented. Thanks to these comprehensive quality-assurance measures, an extremely high degree of homogeneity and thus, material safety, can be reached for this natural material.<\/p>\n<p>The success of structural mass timber construction in the last 20 to 30 years is based in large parts on the safe adherence to the above mentioned quality processes. The HASSLACHER group is a pioneer in this area and regularly invests in state-of-the-art production technology to further advance this commitment to quality. The HASSLACHER group\u2019s many references involving demanding construction schemes that were and are realised all over the world are the best proof.<\/p>\n<p><a href=\"https:\/\/www.hasslacher-greentower.com\/en\/quality-assurance-in-the-production-process-of-the-timber-hybrid-tower\/\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\">Learn more &gt;<\/span><\/a><\/p>\n\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                                                            <div class=\"accordion-item \">\n                                    <span class=\"arrow\">\n                                        <i class=\"fa-thin fa-chevron-down\"><\/i>\n                                    <\/span>\n                                    <div class=\"accordion-title\">\n                                        <span class=\"plus\">\n                                            <i class=\"fa-solid fa-circle-plus\"><\/i>\n                                        <\/span>\n                                        <span class=\"title\">Is it risky for a project operator or investor to choose such a new tower concept?<\/span>\n                                    <\/div>\n                                    <div class=\"accordion-content\">\n                                        <div class=\"accordion-content-inner\">\n                                            <p>Wind turbines are highly stressed structures and experience shows that such systems experience frequent issues. This was clear to us from the very beginning of development. This is why we only use technology that has been tested and proven for decades for our tower concept. We possess decades of experience with tower and bridge structures from glued laminated timber that are exposed to the weather and dynamic loads.<\/p>\n<p>Even in the use of rod dowel connections for dynamically stressed structures, we can draw on decades of experience. Additionally, we avoid all bonding processes at the construction site, that \u2013 according to our experience \u2013 can hardly be performed in a quality-assured way under critical weather conditions and associated time and cost pressure. 125 years of experience on how to develop and build timber structures, combined with state-of-the-art quality assurance methods and concepts flow into our pilot system projects. This will confirm the tower\u2019s structural stability that was proven in the test report.<\/p>\n\n                                        <\/div>\n                                    <\/div>\n
