What is BS EN 14964 - Rigid underlays for discontinuous roofing about?
BS EN 14964 is one of the European standards that discuss rigid underlays for discontinuous roofing.
BS EN 14964 specifies the technical requirements for factory-made flat or profiled sheets (wood-based, fibre cement flat sheets or corrugated bituminous sheets or other materials which can be characterised as one of these materials) that are used as underlays in pitched roof constructions with discontinuously laid coverings (e.g., tiles, slates). BS EN 14964 also establishes methods of inspection and testing as well as criteria for evaluation of conformity.
Note: BS EN 14964 does not include rigid underlays which have a stiffening function or a load-bearing function.
