They provide superior thermal insulation and soundproofing, making them the perfect choice for residential and commercial buildings alike. PolyWall cavity wall insulation boards are easy to install and provide superior protection against fire and moisture. This makes them the ideal choice for any insulation projects.


In terms of South African building regulations, to get the required cavity wall thermal insulation R-Value of 1, you need a minimum thickness of 40. The thicker you go the more insulation your get.


Each board is 3m2 so you will need to divide the total wall insulation area by 3 to get the number of boards you require.

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.
