Air Cell Cavity Wall Insulation

Cavity brick walls provide insulation by introducing an air gap between the internal and external brick leaves. The insulation effect can be further enhanced by adding a more effective insulator into the gap. A variety of products are available - we have used the AIR-CELL insulation.

AIR-CELL insulation is a sheet of plastic bubbles (similar to bubble wrap) sandwiched between two reflective layers. The reflective layers act as a barrier to radiant heat transfer, the bubbles prevent heat conduction and the sheet itself lowers convective flow.

The shots below show it being installed.
