| Use advice for data set | Scope: This declaration concerns Glulam produced by Schilliger Holz AG in accordance with /EN 14080:2013/: glued laminated timber and the following glued solid timber: "Massivholzträger (MHT)", "Lamellenbalken (LAM)", "Rigibalken (RBS)", and"Rahmenbaukanteln (RBK)". The production site is the plant in Küssnacht, Switzerland. System boundary: This EPD represents a 'cradle-to-gate' analysis, with options. The manufacturing process of the Glulam products (modules A1-A3) comprises the forestry processes, the transportation of the round timber to the sawmill, the production of the sawn timber and the related background processes (power generation, extraction of fossil fuels, etc.). Furthermore, the production of the glue, as well as the packaging, is also reflected in the analysis. The infrastructure required for the sawmill and the Glulam plant is estimated. According to the applicable PCR, the content of biogenic CO2 is accounted for as a negative input to the global warming potential (GWP). Waste and secondary materials or secondary fuels are not used in production. Bark, wood -chips -shavings and other raw sawdust leave the product scope as co-products. In module A4, an average transport distance of over 90km for the Glulam to reach the prospective construction site is accounted for. Module A5 includes the disposal of PE packaging in a waste incineration plant (WIP).The heat and electricity generated in the WIP are offset as exported energy in module D. Installation material is not reflected in module A5, as the type and quantity of installation material varies depending on the use of the glued wood; installation material must be considered accordingly when assessing a building. Module C2 comprises the transport of the reclaimed Glulam to a biomass power plant. Module C3 depicts the chopping of the reclaimed Glulam; in accordance with /EN 16485/, it is assumed that non-pressure-treated waste wood reaches the end of its waste-state when it becomes available as wood chips. The chipped wood, including its content of biogenic C (as CO2 equivalent) and its content of renewable primary energy, leaves the product system as secondary fuel. In module C4 contains no processes/environmental impacts. Module D calculates the energy recovery of the wood chips in a biomass power plant. It is assumed that the recovered energy will replace the electricity mix in Germany and heat from industrial natural gas firing. The exported energy recovered from the PE packaging (module A5) is calculated analogically. | ||
| Technical purpose of product or process | The Glulam is used in structural engineering as visible or concealed load-bearing elements, such as in bridges and buildings. "MHT", "LAM" and "RBS" are also used in structural engineering, "Rahmenbaukanteln" are intended as uprights for timber frame construction and as sleepers in prefabricated-building construction. | ||

| General comment on data set | Schilliger glued laminated timber (Glulam) is an industrially manufactured wood product for load-bearing structures. It is used in building and bridge construction. Its composition is symmetrical and consists of at least two dried boards of coniferous solid wood glued together parallel to the grain. As a result of the strength grading of the raw material and the homogenisation, it is reinforced through its layered formation and has higher load-bearing capacities than conventional timber. The glued laminated timber (Glulam) and glued solid timber product-groups are defined according to /EN 14080:2013/, (/1359-CPR-0622/). Glulam is characterised by a lamellae thickness of 40 mm and can be utilised in a wide range of applications, due to its high strength and variable product characteristics. Glued solid timber has either thinner or thicker layers than 40 mm and is produced for special requirements: this includes the company's own products,"Massivholzträger (MHT)", "Lamellenbalken (LAM)", "Rigibalken (RBS)" and "Rahmenbaukanteln (RBK)". A comprehensive description of Glulam and glued solid timber products can be found on the company website at "www.schilliger.ch". | ||

| Technology description including background system | Technical data: Schilliger-Glulam fulfils the requirements of /EN 14080:2013/ (/1359-CPR-0622 /). These are further elaborated in the declarations of performance for Glulam (silver fir/spruce) / SHI / 01-01012016 of 1.1.2016 and for glued solid timber (silver fir/spruce) / SHI / 04-01012016 of 1.1.2016. Details of the cross-sectional structures and the properties of each product can also be found in the technical data sheets published by the company on its website. Declared unit: The declared environmental figures refer to 1 m3 of glued wood in accordance with EN 14080:2013, including Glulam and solid glued timber, with all products having been glued using PUR adhesive. For the statistical modelling of the sawing processes, the production of planks (not beams) was conservatively estimated; however, for the glue consumption, the consumption for Glulam or glued solid timber, weighted according to production volume, was used. | ||
