approval or an approval in accordance with the /Biocides Directive/. 2.3 Technical Data a) Cross-laminated timber as per ETAs The product's performance values are to be declared in the Declaration of Performance based on the respective /ETA/. Properties and the scope of the Declaration can vary depending on the /ETA/. Technical construction data’D 1) For cross-laminated timber made from coniferous wood 2> Some ETAs permit other equivalent measurement processes. 3) Treatment with a wood preservative in accordance with /DIN 68800-1/ is only permissible if the structural measures have been exploited...

Fire protection Max. length: 16 m - 20 m 2.5 Base materials / Ancillary materials X-LAM comprises at least three layers of technically dried coniferous wood boards or plank laminations glued together crosswise. Polyurethane adhesives (PUR) or melamine-urea-formaldehyde adhesives (MUF) are used for basic duroplastic gluing as well as emulsion polymer isocyanate adhesives (EPI) in smaller quantities. Formaldehyde emissions are declared in accordance with /DIN EN 14080/. Substances on the /ECHA List of Candidates/ for including substances of very high concern in Annex XIV of the /REACH Directive/...

No ingredients are leached which could be hazardous to water. Mechanical destruction X-LAM breakage features display an appearance which is typical for solid wood. 2.14 Re-use phase In the event of selective rebuilding after the end of the usage phase, X-LAM can be easily reused. If X-LAM cannot be recycled, it is directed towards thermal recycling for generating process heat and electricity on account of its high calorific value of approx. 19 MJ/kg. During energetic recycling, the requirements outlined in the /Federal Immission Control Act (BlmSchG)/ must be maintained: Untreated cross-laminated...

3.7 Period under review Data for the primary system was surveyed during the period 2009 to 2011, whereby data was always provided for the full calendar year. The data is therefore based on 2008 to 2010. All information is based on averaged data for 12 consecutive months. There is a Studiengemeinschaft Holzleimbau e.V. document in place confirming that the primary data used continues to depict the association in a representative manner. 3.8 Allocation The allocations comply with the specifications of the /EN 15804/ and /EN 16485/, and are explained in detail in /S. Ruter, S. Diederichs: 2012/....

Waste heat used (per net flow of declared unit) The product is recycled in the form of waste wood in the same composition as the declared unit at the endof-life stage. Thermal recovery in a biomass power station with an overall degree of efficiency of 54.69 % and electrical efficiency of 18.09 % is assumed, whereby incineration of 1 tonne atro wood (mass value in atro, consideration of efficiency, yet ~18 % wood moisture content) generates approx. 968.37 kWh electricity and 7053.19 MJ useful heat. Converted to the net flow of the atro wood percentage included in Module D and taking consideration...

The interpretation of results focuses on the production phase (Modules A1 to A3) as it is based on specific data provided by the company. The interpretation takes the form of a dominance analysis of the environmental impacts (GWP, ODP, AP, EP, POCP, ADPE, ADPF) and the use of renewable/nonrenewable primary energy (PERE, PENRE). Accordingly, the most significant factors for the respective categories are listed below. 6.1 Global Warming Potential (GWP) When considering the GWP, the CO2 product system inputs and outputs inherent in wood require separate analysis. A total of approx. 876 kg CO2 enter...

BSP^Holz system in the form of carbon stored in the biomass, of which 48 kg carbon dioxide are emitted along the upstream chains and 75 kg within the framework of heat generation on site. The volume of carbon ultimately stored in the cross-laminated timber is extracted from the system again when recycled in the form of waste wood. Fig. 1: CO2 product system inputs and outputs inherent in wood [kg CO2 equiv.]. The inverse indications suggested by inputs and outputs is in line with the LCO CO2 flow analysis in terms of the atmosphere. 34 % of the analysed fossil greenhouse gases are accounted for...

outlined in section 5. These deviations are primarily attributable to differences in the fuels used and specific electricity consumption values during the processes. BSP^Holz Maximum deviations of +3 %/-16 % (GWP), +102 %/55 % (ODP), +1 %/-6 % (AP), +9 %/-6 % (EP), +19 %/13 % (POCP), +91 %/-66 % (ADPE) and +3 %/-8 % (ADPF) were calculated in relation to the results 7.1 Formaldehyde In accordance with the manufacturer-specific European technical assessments, formaldehyde emissions are established with reference to /DIN EN 717-1/. The European technical assessments specify testing with a loading...
