If you are designing or building a new luxury home, commercial or industrial building then you should really consider insulating your walls with PolyWall Insulation Boards.


Cavity Wall Insulation is not expensive and by installing it you will stop the heat from outside affecting the inside room temperature of the building. During winter it will also keep the cold outside. This means that your heating and cooling systems work less hard to maintain a comfortable room temperature and in so doing you will save considerably on electricity costs.


Cavity Wall Insulation, for exterior brick walls is a really important insulation layer in new buildings and Polywall Fire Retardant Polystyrene Insulation Boards are extremely-effective in this application.


Building regulations require that a minimum thermal insulation value of 1 be met in terms of the insulation layer between cavity wall layers.


For residential homes we recommend 40mm PolyWall Insulation boards. Obviousely if more insulation is required then thicker boards can be ordered.


This hidden polystyrene wall insulation layer, like our PolyFloor concrete floor insulation product, ensures that the whole building envelope is thermally efficient and can only be installed when the walls are actually being built.

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.
