Design considerations should align with the guidance provided in BS 4841: Part 3 and the Single Ply Roofing Association recommendations.
Flat roof falls must be consistent and sufficiently steep to prevent water pooling and ensure effective drainage.
The fire rating of our 150mm Unilin FR-MG, when assessed to EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test', depends on the waterproofing system selected.
An approved, continuous vapour control layer should be positioned beneath the insulation (except over sealed metal deck systems). For mechanically fixed boards, employ a minimum 1000 gauge polythene vapour control layer, lapped and sealed using double-sided tape, positioned below the Roof insulation. At vertical upstands and service penetrations, the VCL must be extended upwards and sealed to fully contain the insulation layer before roof finishing.
