How do I know if my walls need insulated?

Your home will usually be suitable for cavity wall insulation if it is over ten years old and its external walls are unfilled cavity walls. In some cases houses are built without a cavity so it m ay be necessary for the Energy Surveyor to have a quick check by means of a boroscope inspection. They will drill a small hole in your external wall to see if your walls are hollow or filled.

Wall Insulation FAQ’s

Is my home suitable for cavity wall insulation?

If your house was built between the 1920’s and the 1990’s it is likely that your exterior walls have a double skin of bricks with have a cavity, or gap, between them. Houses built before this period were built with solid stone. Any residential properties built lkater than ths are likely to have insulation already installed.
If your home was constructed using solid walls, or has a timber frame, it is not suitable for cavity wall insulation.

What material is used to insulate walls?

There are three main types of materials used to insulate walls. Polystyrene beads, mineral wool fibre and foam insulant. Although all three are manufactured to British building standards foam is rarely used now to insulate residential properties.

How can I tell if my walls have a cavity?

You can tell the type of walls you have either by measuring the thickness of the wall near the door. If it is 260mm or more then you probably have a cavity. Another waqy is to look at the pattern of the bricks on your walls. The diagram below shows how cavity walls have a regular brick pattern so as to leave a gap in between the brick leafs. Solid walls have an alternative pattern as no space is required in between the bricks.

Cavity Wall Insulation – Benefits

Cavity Wall Insulation stops heat escaping out through the walls of your home. Around 35% of heat in the average home in Scotland and the UK is lost through the outer walls of the house. Under the current Government insulation grants scheme thousands of SEdinburgh homeowners, landlords and private tenants qualify for a grant for cavity wall insulation.

If your home was built after 1920, it probably has walls  with a gap or cavity between them. Wall insulation fills that gap, keeping the warmth in to save energy. It can also help reduce condensation inside the house if this is a problem on your external walls.
