PIR insulation for flat roofs
PIR insulation for flat roofs is commonly considered in warm-roof constructions, where the insulation sits above the structural deck and beneath the waterproofing. A compact insulation layer can help achieve thermal performance within a limited roof depth. The correct board depends on the membrane, attachment method, loading and roof design. Drainage falls, vapour control and detailing around outlets and penetrations are just as important as the insulation itself. ecoPIR welcomes enquiries for new flat roofs and refurbishment projects. Share the roof build-up and required performance so that current product information can be considered against the design.
Build a complete warm-roof system
Specify insulation together with the waterproofing system. The facing, adhesive or mechanical fixing and substrate must be compatible. A roof that carries regular access, plant or other loads needs a construction designed for those conditions.
What to confirm before ordering
- Roof area, structural deck and existing build-up.
- Waterproofing membrane and attachment method.
- Required thermal resistance and available thickness.
- Drainage falls, outlets and upstand heights.
- Compressive performance and expected roof loading.
A flat roof must shed water reliably; insulation is not a substitute for a waterproof layer. See PIR boards or send your project details.
