The version of the construction detals filed by SINTEF at any time is a formal part of the approval.. Fields of application Kriaute Building System may be used for assembling multistorey residential buildings with maximum four stories, in fire class and 2 according to the provisions of the Regulations on technical requirements for building works (TEK). The building system may also be used for other type of buildings, providing the performance requirements for the building are assessed in relation to the declared performance of the elements. 4. Properties 4. Load-carrying capacity The mechanical resistance and stability of all structural components are calculated in full for each individual building project, see also point Table Fire resistance for standard Kriaute Building System as desribed in cl. 2 Structure Equivalent fire restistance External wall, fig.

Reaction to fire Gypsum board internal lining is classified as A2-s, d0 according to EN 50-. External wood cladding is classified as D-s2, d0 according to EN 50-. Roofing shall be class B ROOF (t2) if no other requirement follows from TEK Sound insulation With separating wall and floor design, and construction details and connections as described in chap. 2, the sound insulation properties in accordance with NS-EN ISO 628- and NS-EN ISO as well as NS-EN ISO 77- and NS-EN ISO 77-2, are estimated to be as indicated in Table 4 for completed house constructions. This corresponds to sound insulation class C in accordance with NS 875 for residential houses. The sound insulation performance depends also on the installation of pipes, ducts and cables for each individual building, which has to be assessed case by case.

Thermal loss due to extra timber used around door- and window openings, are not included. Thermal transmittance for other roof constructions installed on top of the elements are calculated case by case in full for each building project.

Substances hazardous to health and environment The elements contain no hazardous substances with priority in quantities that pose any increased risk for human health and environment. Chemicals with priority include CMR, PBT or vpvb substances. 5.2 Effect on soil, surface water and ground water The leaching properties of the elements are evaluated to have no negative effects on soil or ground water. 5. Handling of waste The elements shall be sorted as wood, metal, gypsum, residual waste or other appropriate waste fractions on the building/demolition site, and delivered to an authorized waste treatment plant for material recovery, energy recovery or disposal. 5.4 Enviromental product declaration No environmental declaration (EPD) has been worked out for the product. 6. Special conditions for use and installation 6. Design considerations in general The production and delivery of elements shall be based on a structural design, fire resistance and thermal insulation according to the requirements for each individual building. The requirements and necessary design calculations shall be available before production and deliverance of the elements. 6.2 Structural design The structural design of each element shall be in accordance with NS-EN (timber structures) and NS-EN 99--, and 4 (loads) with national annexes NA. The structural design shall comprise vertical and horizontal load capacity of walls, floor and roof, and include anchoring to the foundations. 6. Fire resistance design The production of each element shal be based on a full structural fire design applicabel to the overall fire design requirements for the complete building. This includes all fire resistance performance not covered by the performance listed in chapter 4.2 and table Thermal insulation design For each project using elements according to this approval the design and production shall be based on the required maximum thermal resistance and transmittance for the complete building. 6.5 Foundations The elements shall be installed on foundations designed according to the principles shown in SINTEF Building Research Design Guide 52.20, and with dimensions and level tolerances that satisfiy the manufacturer s requirements. Moisture transport from the foundations to the building elements shall be prevented by a capillary breaking layer. 6.6 Installation in general The elements shall be installed and connected according to the details shown in "Standard Construction Details for Kriaute Building Systems belonging to SINTEF Technical Approval No " as long as no specific installation details have been worked out for each individual project. 6.7 Transport and storage Before installation of the elements must be stored in a dry environment and protected from precipitation.
