Insulation helps save money

Heat is energy, and en- 1 ergy costs money. Insulat- i ing a house makes good < sense, like giving your car a tune-up or mending a , hole in your wallet. Airfoam is probably the ' only material that can be ■ used in existing walls, ; whether brick veneer, , concrete block, weatherboard or synthetic materials. ' Installation is simple, i Small holes are bored in the wall and the foam i injected into the 1 wall cavity through them. 1 Once insulation is com- 1 plete, the holes are tightly plugged and sealed with 1

adhesive and the surface is restored to the original condition. The injection method can be used from either inside or outside of the building. As well as providing protection from the winter cold or summer heat, the foam helps to eliminate mildew and mould, and acts as a sound barrier keeping out noise. The potential for en-ergy-saving £jnd increased thermal comfort that this technique offers is very large. As the majority of homes in this country are

not insulated in the walls, most can be treated with Airfoam, and all of these would benefit greatly from Its use. Within minutes of in-, jecting the liquid foam into the cavity, it begins to form a firm, resilient filling which contains millions of tiny bubbles of still air. These act like pockets of air trapped between the feathers in an eiderdown which minimise air circulation and hence, heat loss. Unlike feathers, however, Airfoam does not pack or fall down to leave cold spaces.

Once installed Airfoam insulation continues to work with absolutely no maintenance, and it does not attract insects or vermin.
