Roof Design

The 50mm Unilin Insulation Boards are compatible with an extensive range of bitumen-based waterproofing systems. These typically comprise a BS EN 13707:2013 type 3G perforated base layer or a proprietary waterproofing system. Installation should position the fleece side upward, though full bonding represents an alternative approach. For moisture and condensation management guidance, refer to BS 8217 specifications for reinforced bitumen membranes in roofing applications.

Falls

Flat roof design must incorporate appropriate falls to prevent water pooling and ensure effective drainage.

Roof Loading

The 50mm Unilin FR/BGM boards suit roof decks with minimal foot traffic and low maintenance requirements. Where regular pedestrian access is needed, install dedicated walkways. Following roof completion, protective boarding should be laid if additional site work is anticipated, preserving the roofing system's integrity.

Roof Finish

Built-up roofing systems require finishing with a reflective protective layer such as chippings. Consult the system manufacturer for specific recommendations.

Fire Performance

Fire rating, when assessed to EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test', depends on the specified waterproofing system.

Vapour Control Layer

Prime decks before applying hot bitumen for vapour control layer bonding. Reference BS 8217 for application procedures. Extend the VCL beyond the insulation and seal at the parapet wall.
