External Foam & Coatings

foam-coating01Foam 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.

Benefits:

  • 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

Applications:

  • Built-up felt roofs
  • Asphalt
  • Sheeted fibre cement
  • Steel
  • Aluminium
  • Slate
  • Concrete
  • Glass

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.
