A Designer's Guide to Specifying Warranted 316 Austenitic Stainless Steel Fasteners and Sealants

Description

Fastener specification is critical to the performance of roofing and cladding systems. The fastener works in close combination with sealants, so therefore the specification of the fastener and sealing products needs to be addressed at the early stages of detail design, to allow the completed envelope to perform throughout its life.

This design guide addresses the principle performance criteria of fasteners and sealants, namely durability (corrosion resistance), weathersealing, the Part L issues of airsealing and thermal bridging, aesthetics, and technical performance.
