ROOFBOARDS – PITCHED ROOFS
Loft insulation is the most common form of roof insulation used today with mineral fibre being the most commonly used insulation material. However, 33% of homeowners would like an extra bedroom whilst 43% said they did not have enough storage space. With building land at a premium it is therefore easier to increase the living area “vertically”. The use of rafter level insulation is rapidly increasing in creating a warm roof space which can then be used for a warm storage area or may be fully convered to a “room in roof”. Polyurethane (PUR) and Polyisocyanurate (PIR) insulation products can be used to achieve this.
PUR/PIR insulation boards offer flexibility to the specifier; they can be used over rafter, between rafters or under rafter. They can also be used in a combination of between and over or between and under.
The use of PUR/PIR insulation products to insulate a pitched roof is equally applicable for new-build or refurbishment. The thermal performance and flexibility offered by rigid PUR/PIR insulation products means that the pitch of the roof can be insulated to current standards and beyond without sacrificing valuable headroom.
Benefits of PUR/PIR insulation products for Pitched Roof Applications:
- Provides the best thermal performance;
- Constant thermal performance for lifetime of the building;
- Resistant to moisture ingress;
- Non-fibrous and do not emit harmful emissions;
- Does not support the growth of fungi;
- Easy to handle and install
