Cavity Wall insulation

Cavity Wall insulation is a quick and cost effective way to start saving money through energy efficiency. While many people think of insulating their roofs in an effort to save energy, it is also the walls that you need to be concerned with. If your home was built before the 1980’s, it is likely that you have walls with open cavities – a major source of heat loss for many buildings.

  • Why Cavity Wall Insulation? Reduce your energy bills by approximately £140 per year
  • Cost effective form of insulation
  • Easy to install – can be completed in a matter of hours

Help your wallet, help the environment, reducing carbon emissions and your bills.

How it works

Many homes built before the 1980’s have walls that were built with 2 layers of brick and a small gap in between. Air can act as insulation – as long as it is not moving. Unfortunately, the air that is in this brick wall cavity is not static, in fact it is transferring heat from inside your home to outside. This is a major issue for many homeowners in Glasgow, Edinburgh and around Scotland, who are living in properties constructed before more efficient building methods replaced the cavity wall.

By filling in the cavity with insulation materials you restrict the movement of air, keep valuable heat inside your home, and reduce your energy costs. Simple.
