Solid External Wall Insulation & Render System

Around 45% of the heat lost in an un-insulated solid walled home is through the walls. Insulating your solid walls can reduce heat loss and can save you up to £400 a year on your fuel bills.

What is solid wall insulation?

If your home was built before or around 1920, its external walls are likely to be solid rather than ‘cavity walls’. Cavity walls are made of two layers with a small gap or ‘cavity’ between them. This cavity acts as a barrier to reduce heat flow through the wall. Click here to find out more about cavity wall insulation

Solid walls have no such gap and this allows more heat to pass through them than through cavity walls. In fact, twice as much heat can be lost through an un-insulated solid wall as through an un-insulated cavity wall. But the good news is that, like cavity walls, solid walls can be insulated.

What are the benefits of solid wall insulation?

Solid 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.

So, insulating your walls will help to heat your home more efficiently. Using less energy reduces carbon dioxide (CO2), one of the biggest causes of climate change. It will help you to stop wasting money on your energy bills too.

What could you save?

Solid walls that are insulated using external insulation (from the outside) can make your home warmer and more comfortable, and greatly reduce your heating bills at the same time - in fact, by insulating your solid walls you could cut your heating costs by up to 40%.

Cavity walled properties can also benefit from the same kind of solid wall insulation, especially if the cavities are not suitable for filling.

Is solid external wall insulation suitable for your home?

External wall insulation will be more cost effective if your external walls need re-rendering; you may need planning permission if your property is listed or located within a conservation area. External wall insulation.

  • Can be applied without disruption to the household and does not reduce the floor area of your home
  • Renews the appearance of ageing outer walls. Planning permission may be required so check with your local council before undertaking any work
  • Fills cracks and gaps in the brickwork, which will reduce draughts
  • Increases the lifetime of a home’s wall by protecting the brickwork.
  • Reduces condensation on internal walls and can help prevent damp, although it will not solve rising or penetration damp which must be resolved prior to insulating the walls
  • Is ideally installed at the same time as other refurbishment work to outer walls as this will save you a lot of money
  • Requires good access to the outer walls so that the installers can apply the insulation
  • Not recommended if the outer walls are structurally unsound and can not be repaired

How is a solid wall insulated from the outside?

A layer of insulation material is fixed to the walls with mechanical fixings and adhesive, then covered with a special type of render (plaster work) or cladding. The finished look can be smooth or textured and painted, tiled, panelled, pebble-dashed (for easy maintenance) or finished with brick slips to provide a real masonry brick finish.

As this will cover the whole of the outside of your property, any of these finishes are likely to change its appearance – and will cover existing brickwork. Therefore you must ask your local council whether you need planning permission.

How can I tell if I have solid or cavity walls?

Most houses built after 1930 have cavity walls. You can usually spot cavity walls from their depth (walls more than 260mm thick are probably cavity walls) and by the pattern of the bricks. If the bricks are all ‘side-on’, with their long sides showing, there is probably a cavity. If the pattern is mixed, with some bricks showing the shorter end-piece, they are probably solid.
