| Use advice for data set | Scope: This document refers to average HASSLACHER glued laminated timber, glued solid timber, block glued glulam and special components manufactured at the following production sites: - NORITEC Holzindustrie GmbH in Sachsenburg (Austria), - HASSLACHER Holzbausysteme GmbH in Hermagor (Austria), - HASSLACHER Holzbauteile GmbH & Co. KG in Kleinheubach (Germany) and - NORDLAM GmbH in Magdeburg (Germany). System boundary: The life cycle assessment of HASSLACHER glued 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 plants in Sachsenburg, Hermagor, Kleinheubach and Magdeburg. Sorting, planing, finger-jointing, pressing, and joining, including the packaging of the product, are taken into account. The electricity demand of the Austrian production sites in Sachsenburg and Hermagor are covered entirely by green electricity (emission factor GWP-total: 13 g CO2 equivalent/kWh). Thermal energy is provided from the energetic use of wooden residues from the production process. In Magdeburg, thermal energy is delivered by the adjacent waste incineration plant. Emissions of the waste recovery process are attributed to the product system from which the waste originates. As a result, thermal energy is considered burdenfree in the calculation. 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. Module 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. Module 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 | Glued laminated timber is used in all structural areas of modern timber construction, i.e. from engineering-based residential and industrial construction to bridge building. Glued laminated timber, with the exception of glued solid timber (only service classes 1 and 2), can be used in service classes 1 to 3 according to EN 1995-1-1. 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 is not sufficient on its own. 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 | Glued laminated timber (the term also includes glued solid timber, block glued glulam and special components throughout this document) from HASSLACHER Holding GmbH is a solid, rod-shaped timber element consisting of at least two dried softwood lamellas bonded parallel to the fibres. The glued laminated timber is manufactured according to EN 14080. A high degree of dimensional stability and load-bearing capacity is achieved through visual or mechanical strength grading of the board lamellas and homogenisation of the visual and physical material properties. Glued laminated timber is usually made from spruce, fir, pine or larch. The standard strength classes are GL24h, GL24c to GL32h and GL32c. Glued laminated timber is available as standard or commissioned goods as well as in special dimensions and special constructions or in the form of special components. 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. Production is subject to in-house and external monitoring in accordance with EN 14080. | ||

| Technology description including background system | For the production of glued laminated timber, conventional sawn timber is first dried to below 15 % wood moisture (target moisture content: approx. 12 ± 2 %), pre-planed and graded visually, but mainly by machine, according to strength. Board sections with strength-reducing or visually inappropriate areas are cut out depending on the required or desired strength classes or quality demands and the resulting boards are joined by finger joints to form endless lamellas. In the subsequent pre-planing process, the board lamellas are planed to the desired final thickness of > 6 to 45 to < 85 mm in the case of glued solid timber), in order to be able to be bonded after the adhesive has been applied to the broadside. After the adhesive has been applied to the broadside, they are pressed in a straight or curved press bed to form at least two-layer glulam blanks. After curing, the blank is planed, chamfered, tied and packed. If required, a treatment with surface finishes (end-grain protection, UV protection, glazes, assembly and hydrophobic protection, etc.) can be carried out before packaging. Technical data: Structural data for glued laminated timber according to EN 14080 are given. 2 Declared unit: This EPD refers to a declared unit of 1 m3 of HASSLACHER glued laminated timber with an average density of 470 kg/m³ at 13 % moisture at delivery. | ||
