2Scope / Description
This standard addresses the construction of timber-based and wood panel underlayment for roofing. Within the scope of this standard, "underlayment" refers to the roof deck and under-roof structure, covering the construction of the roofing underlayment system. Fasteners covered by this standard include metal fasteners such as nails, screws, and clips. The standard is intended for manufacturers, designers, and end users; however, its simplified presentation of the metal fastener section from standard EVS-EN 1995-1-1 is primarily aimed at skilled tradespeople, specifically roof builders. These technical provisions are aligned with standard EVS 920-1 and shall apply unless otherwise specified in the construction project documentation or the manufacturer's installation instructions.
