Masonry and cavity wall insulation

Brick, masonry and concrete walls are essential parts of modern day construction, but they have very low thermal values. Masonry and brick are very good at storing heat but they are also very good at transferring heat. They heat up during the day and then radiate that heat back into the building, putting strain on the cooling systems. Extruded polystyrene acts as a barrier, limiting this transfer, reducing the need for artificial air conditioning and reducing energy consumption.

A double brick cavity wall has an R-value of only R0.69. In comparison, just 30mm of Foamular Extruded Polystyrene Insulation has an R-value of R1.07. Combining the two would provide an R-value of 1.76 and vastly improve the walls thermal performance.
