Cavity Wall Insulation

In order to keep your energy costs down, you may consider Cavity Wall Insulation. This is the installation of an insulating material in the air space of a Cavity Wall. Materials used include: 

  • Glass fibre 
  • Rock Wool 
  • Wool 
As a Cavity Wall Installation leads to greater energy efficiency, the government and energy companies are often willing to subsidise the cost of them.

Cavity Wall Insulation must be installed correctly by experienced professionals. If it is not done correctly, the insulating material may form a bridge between the two parts of the wall. This may allow moisture to travel from the exterior of the house to its interior.
