Some brief information on Cavity Wall Insulation.

Two main types of Cavity Wall Insulation:

  • Double Leaf Wall type insulation - this consist of delivering insulation material between an outer and an inner wall in your house
  • Single Cavity Block Wall type insulation - this consist of delivering insulation material into individual concrete cavity blocks.

The latter, i.e. cavity blocks can be extremely difficult to in-fill but thankfully most modern construction consists of double leaf/skin walls. The type of infill used should be decided by yourself. The infill can consist of polystyrene beads, foam, etc. ( look up Foam Insulation under Energy and Insulation on this website.)

Advantages of Cavity Wall Insulation:

  • Very low delivery costs, especially for double leaf/skin walls.
  • Fast delivery.
  • Lower Energy Bills.
  • Improved BER rating.
  • Reduced Carbon footprint.

disavantages of Cavity Wall Insulation:

  • It will not be possible to remove all thermal bridges when compared to external wall insulation.
  • In the case of Cavity blocks these are sometimes diffficult to fill completely.
  • Also in the case of Cavity blocks many holes will have to be drilled to apply the insulation material.
