Underlays for discontinuous roof coverings
Development of test methods and the product specification for the characterisation of underlays for discontinuous roofing and underlays ('breather membranes') for walls which are clad in lightweight materials such as timber and metals.
General Information
This document specifies instructions for mounting and fixing for reaction to fire testing of factory-made underlays for discontinuous roof coverings and walls and contains provisions for direct and extended application rules.
These mounting and fixing procedures are not intended to be used for flat roofed waterproofing applications.
