Roof Design

The 140mm Unilin Insulation Boards are engineered for compatibility with a broad spectrum of bitumen-based waterproofing systems. These typically comprise a BS EN 13707:2013 type 3G perforated base layer or proprietary roof waterproofing solutions. Installation should position the fleece side facing upwards, though full bonding remains an alternative approach. Refer to BS 8217 guidelines for moisture and condensation management in reinforced bitumen membrane roofing applications.

Falls

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

Roof Loading

The 140mm Unilin FR/BGM boards suit roof decks with minimal foot traffic and low maintenance requirements. Where regular pedestrian access is required, protective walkways should be installed. Following roof completion, protective boarding is recommended if additional site works are necessary, protecting the roofing system integrity.

Roof Finish

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

Fire Performance

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

Vapour Control Layer

Decks require priming before applying hot bitumen for vapour control layer bonding. Consult BS 8217 for application procedures. Extend the VCL beyond the insulation and seal against the parapet wall.
