This Agrément Certificate Product Sheet relates to the Synthesia Range of Insulation for Roofs, spray-applied in-situ thermal insulation for pitched roofs with a roof tile underlay, tiled or slated pitched roofs without a roof tile underlay, the underside of flat roofs and hybrid roofs of new and existing dwellings or similar buildings.
BBA polyurethane system for roofs includes:
- Factors relating to compliance with Building Regulations where applicable
- Factors relating to additional non-regulatory information where applicable
- Independently verified technical specification
- Assessment criteria and technical investigations
- Design considerations
- Installation guidance
- Regular surveillance of production
- Formal three-yearly review.
Key factors assessed
- Thermal performance – Depending on their thickness, the products have a declared thermal conductivity value of between 0.025 W/m·K and 0.027 W/m·K for Poliuretan Spray RF-352D and between 0.026 W/m·K and 0.028 W/m·K for Poliuretan Spray S-353E.
- Condensation risk – The products have a water vapour resistance factor of 60 (resistivity of 300 MN·s/g·m) for Poliuretan Spray RF-352D and 80 (resistivity of 400 MN·s/g·m) for Poliuretan Spray S-353E. The risk of interstitial condensation will depend on the roof construction and should, therefore, be assessed for each project.
- Durability – The products will have a life equivalent to that of the structure in which they are incorporated.
