Roof Design

Consideration should be given to the recommendations of BS 4841: Part 3 and those of the Single Ply Roofing Association.

Falls

The fall on a flat roof should be constant and steep enough to ensure that rainfall does not pond.

Fire Performance

The fire rating of our 90mm Xtratherm FR-MG, when tested to EN 13501-5 and BS 476 Part 3 ‘External Fire Exposure Roof Test’, will be dependent upon waterproofing system specified.

Vapour Control Layer

A continuous, approved, vapour control layer should be used below the insulation. (Unless over a sealed metal deck system). For mechanically fixed boards, a minimum vapour control layer of a 1000 gauge polythene layer lapped and sealed with double-sided tape should be used below the Roof insulation. At vertical upstands and penetrations, the VCL should be turned up and sealed to encapsulate the insulation layer prior to the roof finish being completed.
