| Use advice for data set | Scope: This document refers to average HASSLACHER CROSS LAMINATED TIMBER of the HASSLACHER group. This EPD includes data of the NORITEC Holzindustrie GmbH in Stall im Mölltal (Austria) and represents 100 % of HASSLACHER’s CROSS LAMINATED TIMBER production in the year of reference. System boundary: The life cycle assessment of HASSLACHER CROSS LAMINATED TIMBER refers to a cradle-to-gate analysis of the environmental impacts with modules C1-C4 and D (A1-A3, + C, +D). The following life cycle phases are taken into consideration in the analysis: Module A1-A3 | Production stage The production stage includes the upstream burdens of raw material supply (sawn timber, production of the adhesive system, etc.) and their transports to the manufacturing plant in Stall. Sorting, planing, finger-jointing, chamfering and joining, including the packaging of the product, are taken into account. The share of electricity demand covered by green electricity is 100 % (emission factor GWP-total: 13 g CO2 equivalent/kWh). Thermal energy is provided from the energetic use of wooden residues from the production process. Module C1 | Deconstruction and demolition After the removal of building components overlying the product, the joints can simply be loosened by screwing or sawing and lifted by cranes to the place of removal. Required energy demand can be neglected. The actual energy demand depends on the installation of the products and can therefore vary greatly in the building context. Module C2 | Transport to disposal Module C2 includes the transport to waste treatment. In this case, transport by truck over a transport distance of 50 km is assumed. Module C3 | Waste processing In Module C3, the chipping after removal of the products is considered. The wooden products and with them the material-inherent properties leave the product system as secondary fuel in module C3. Modul C4 | Disposal The applied scenario declares the energetic recovery of the wooden products; therefore, no environmental impacts are to be expected from waste processing of the products in C4. Modul D | Benefits and loads beyond the system boundary Applying an European average scenario, module D describes the energetic recovery of the product at the end-of-life including the corresponding energy substitution potentials. | ||
| Technical purpose of product or process | HASSLACHER CROSS LAMINATED TIMBER is used in all structural areas of modern timber construction in service classes 1 and 2 according to EN 1995-1-1 in the form of structural elements with predominantly static traffic loads. The use of preventive chemical wood preservation according to DIN 68800-3 is unusual and only permissible if structural wood preservation according to DIN 68800-2 alone is not sufficient. If, in exceptional cases, a preventive chemical wood preservative is used, this must be regulated by a general building authority approval or approval according to the Biocidal Products Regulation. | ||

| General comment on data set | HASSLACHER CROSS LAMINATED TIMBER from the HASSLACHER Group is a solid, panel-shaped timber construction element consisting of layers of softwood bonded at right angles to each other. HASSLACHER CROSS LAMINATED TIMBER is manufactured in accordance with ETA-12/0281 of 09.11.2020. HASSLACHER CROSS LAMINATED TIMBER is manufactured at the sites NORITEC Holzindustrie GmbH in Stall im Mölltal (Austria) and, since 2021, at NORDLAM GmbH in Magdeburg (Germany). The data of the production site of NORITEC Holzindustrie GmbH in Stall im Mölltal (Austria) for the reference year 2019 have been included in this EPD. NORDLAM GmbH Magdeburg produces with the same technologies. The crosswise bonding of the individual lamellas and the generally symmetrical structure of HASSLACHER CROSS LAMINATED TIMBER has the advantage of extremely high dimensional stability, as well as potential load transfer both longitudinally and transversely to the main load-bearing direction. HASSLACHER CROSS LAMINATED TIMBER is defined in its cross-sectional structure by a minimum number of layers of at least three, whereby the maximum number of layers is limited to eleven. HASSLACHER CROSS LAMINATED TIMBER is available in two different strength classes, i.e. CL26E11.8 and CL36E14.7, according to ETA-12/0281. Due to the existing joinery and surface finishing options integrated in the production plants, a high degree of prefabrication and thus a shortened construction time can be achieved. | ||

| Technology description including background system | HASSLACHER CROSS LAMINATED TIMBER is manufactured from spruce, fir, pine, larch, birch, oak and Swiss stone pine, whereby the larch, birch, oak and Swiss stone pine species are primarily used in the form of ‘Excellent’ lamellas for top layers in so-called ‘Excellent' quality. For the production of HASSLACHER CROSS LAMINATED TIMBER, conventional sawn timber is first dried to below 15 % wood moisture (target moisture content: approx. 12 + 2 %), pre-planed and graded visually or mechanically according to strength. Identified areas with strength-reducing spots are cut out depending on the desired strength class. The cut lamellas are finger-jointed to form endless lamellas. The thickness range of the planed single lamellas is 19 to 45 mm, with a width of 80 to 300 mm. The crosswise bonding of the lamellas is carried out using the adhesive listed in chapter 2.5. ‘Excellent’ lamellas according to ETA-12/0281 or wood-based panels according to EN 13986 can also be used for the visual qualities. After the adhesive has fully cured, the final surface treatment is carried out as well as the customised joinery and packaging. If required, treatment with wood preservatives or surface finishes (end-grain protection, UV protection, etc.) can be carried out before packaging. Technical data: The structural data for HASSLACHER CROSS LAMINATED TIMBER according to ETA-12/0281 are given. Declared unit: This EPD refers to a declared unit of 1 m³ of HASSLACHER CROSS LAMINATED TIMBER with an average density of 470 kg/m³ at 11 % moisture at delivery. | ||
