Flat Roof (BGM)
Warm deck boards suitable under bituminous membranes. Consistent thickness helps achieve target U-values with reliable laps and neat edges. Pair this material with VCL, primers and approved fixings.
Flat Roof (MG)
Warm deck flat roof (MG) boards for single-ply waterproofing systems and partially bonded built-up felt. Stable facer for adhesion and clean bonding lines. Ideal for when fast coverage and predictable thermal performance are priorities.
Loft Roll - URSA/Superglass
Non-combustible glass mineral wool for loft and cold roof spaces. Easy to carry, quick to roll out between and over joists, and great as a practical choice of loft insulation for large areas under roof.
OSB/PLYDECK
Plydeck insulated thermal roof decking board for overlays, decking and local repairs on flat roofs. Provides a stable surface before membranes. Useful with warm roof build-ups and recovery projects in a singular application.
PIR Board
Rigid roof PIR boards with strong thermal performance at practical depths thanks to a lightweight build and feel during installation. Suits warm flat roofs and over-rafter pitched roofs where a slim build-up helps with detailing and weight. They are always an ever-reliable option when it comes to thermal conductivity.
TLX Gold (Multi-foil Insulation)
Breathable gold multi-foil for pitched roofs and refurbishment where depth is limited. Works in hybrid build-ups alongside PIR to reach the required value without excessive thickness.
