LVL performance characteristics : requirements of EN 14279 according to EN 13986:2004+A1:2015

This table covers product use in non structural or structural situations.  Refer also to guidance on essential loadbearing requirements in structural applications as determined by EN 14374  and also relevant standards to determine performance characteristics for end use applications.

Note: The shaded cells indicate essential characteristics which must be determined. Non-shaded cells refer to performance characteristics determined only if required.
