What is Perimeter Wall Cavity Wall Insulation?
- Cavity Wall Insulation is the insulation layer that is placed between the inner and outer brick layers of the outer perimeter walls of a building.
- This insulation layer significantly reduces the transfer of heat and cold through the external perimeter walls of buildings.
- In summer the sun-facing exterior walls get hot and this heat is kept out of the living space by the cavity wall insulation.
- In winter this cavity wall insulation keeps the cold out.
- Cavity wall insulation significantly reduces the energy consumption of such HVAC systems use to keep buildings at room temperature.
