Roof Design

Refer to BS 4841: Part 3 and Single Ply Roofing Association guidance for design recommendations.

Falls

Flat roofs require consistent fall gradients to prevent water pooling and ensure effective drainage.

Fire Performance

Fire classification of this 30mm FR-MG product, when assessed to EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test', depends on the waterproofing system selected.

Vapour Control Layer

A continuous, approved vapour control layer must be installed beneath the insulation (except over sealed metal deck systems). For mechanically fixed boards, use a minimum 1000 gauge polythene layer, lapped and sealed with double-sided tape beneath the Roof insulation. At vertical upstands and penetrations, turn up and seal the VCL to fully encapsulate the insulation before completing the roof finish.
