Roof Design

The 80mm Unilin Insulation Boards are engineered for use with diverse bitumen-based waterproofing systems. These typically employ a BS EN 13707:2013 type 3G perforated base layer or proprietary roof waterproofing solutions. Position the fleece side upward during installation, or alternatively apply full bonding. Consult BS 8217 guidance for condensation and moisture management in reinforced bitumen membrane roofing applications.

Falls

Flat roof design must incorporate adequate falls to prevent water pooling.

Roof Loading

The 80mm Unilin FR/BGM boards suit roof decks with minimal foot traffic and maintenance requirements. Where regular pedestrian access is required, install protective walkways. After roof construction completion, lay protective boarding if additional site work is anticipated, preserving roofing system integrity.

Roof Finish

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

Fire Performance

Fire ratings, determined by EN 13501-5 and BS 476 Part 3 'External Fire Exposure Roof Test' testing, depend on the waterproofing system selected.

Vapour Control Layer

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