Cavity Wall

  • Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs.


• Insulates cavity walls to Building Regulations and Code for Sustainable Homes.
