Foam can be installed to cover large areas quickly and easily to varying depths according to the U-value specified. Sprayed foams bond permanently to any surface that is clean and free from grease and moisture.
- Insulation and weather proofing
- Elastomeric coatings can be applied to the surface of the PU foam application to protect against UV light.
- Sprayed PU foams and elastomeric coatings have been used for the refurbishment of existing roofs for over 40 years
- A range of systems is available, many with BBA testing and approval; British Standards (BS7021 and BS5211) have also been written
- Built-up felt roofs
- Sheeted fibre cement
BUFCA installers are able to assist with the design of a roofing system to meet most requirements and supply a full specification, taking into account substrate preparation, primers, if required, suitable foam systems (typically 40-50 kg/m3 for roof applications) and type of weather coating.
Dewpoint calculations can be compiled to determine the thickness required for condensation control.
