External Wall Insulation

Around 35% of energy used to heat homes is lost through solid walls. The rapid depletion of the world's energy resources, high profile environmental issues such as climate change, are beginning to take precedence and legislation will demand that the thermal performance of any building is strictly governed.

External Wall Insulation involves the mechanical and / or adhesive fixing of insulation boards to the outside of a building, which is then covered with mesh reinforcement, a base coat and a final decorative finish. This layered method encases the property and helps prevent heat from escaping unnecessarily from the property.

External Wall Insulation is an effective way to stop wasting energy and money at home. In winter, a well insulated house keeps warmth exactly where you need it – indoors. Insulating your walls will help to heat your home more efficiently. More importantly it will help you to stop wasting money on your energy bills.

The U-value of a wall is a measure of the rate at which heat passes through the wall and so is a measure of how well insulated the wall is and is expressed in terms of “Watts per meter squared-Kelvin” (W/m² K).

The lower the U-value, the better the performance of the insulation and the less it will cost to heat your home. Heat will always flow from a warm area to a cold one. In winter, the colder it is outside, the faster heat from your home will escape into the surrounding air.

External Wall Insulation slows down the rate at which it escapes, keeping as much of it as possible inside your home for as long as possible. This reduces what is known as the U value of the walls – the rate at which heat can flow through them.

The lower the U value, the more slowly heat is lost – and the more money you will save on your fuel bill to keep your home warm. You could cut your heating costs by up to 40%.
