Roof Design

The 40mm Unilin Insulation Boards are engineered for compatibility with an extensive selection of bitumen-based waterproofing systems. These installations typically incorporate a BS EN 13707:2013 type 3G perforated base layer or proprietary waterproofing solutions. During installation, position the fleece side upwards, or alternatively apply full bonding. Refer to BS 8217 guidelines for moisture and condensation management in reinforced bitumen membrane roofing applications.

Falls

Flat roof falls must be designed to prevent water pooling and ensure effective drainage.

Roof Loading

The 40mm Unilin FR/BGM boards suit roof decks with minimal foot traffic and low maintenance requirements. Where regular pedestrian access is required, install protective walkways. After roof construction completion, lay protective boarding if additional site work is planned, protecting the roofing system's integrity.

Roof Finish

Built-up roofing systems require finishing with an appropriate reflective layer such as mineral 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 selected waterproofing system specification.

Vapour Control Layer

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