BSI | 2021 | 24 |
This document gives guidance for the design of a roof waterproofing system mechanically fastened to the structural deck in relation to wind load resistance. This document is intended to be used together with EN 16002 and the relevant clauses of EAD-030351-00-0402-2019. This guideline does not include the seperate fastening requirements of the insulation boards, the securement to upstands, perimeter fastening, flashings or other roof details.
