Roof Design

The 150mm Unilin Insulation Boards are engineered to work with a broad spectrum of bitumen-based waterproofing systems. These installations typically incorporate a BS EN 13707:2013 type 3G perforated base layer or proprietary waterproofing systems for roof protection. Installation should position the fleece side facing upwards, though full bonding represents an alternative approach. For moisture and condensation management guidance, consult 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 150mm Unilin FR/BGM boards suit roof decks with minimal foot traffic and low maintenance requirements. Where regular pedestrian access is required, install designated walkways. Following roof completion, lay protective boarding if additional site work is anticipated, preserving the roofing system's structural integrity.

Roof Finish

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

Fire Performance

Fire rating classification, determined through EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test' assessment, depends on the specified waterproofing system.

Vapour Control Layer

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