External Wall Insulation

Is My Property Suitable?

If your home was built before or around 1920 or is Victorian, Edwardian or Georgian or even a non-traditional built house, 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. 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.

Over 5 million UK homes built before 1920 were constructed with solid walls of 9 inch brick. With no cavity
to insulate, they are poor at retaining heat in the home and are increasingly expensive to keep warm and dry during winter.

Traditionally, the only method used to insulate solid walls was by internal dry-lining. This has now changed and external wall insulation is now widely recognised as being the most effective thermal improvement for solid wall homes.

What Is External Wall Insulation?

External Wall Insulation can significantly slow down the rate at which heat escapes, keeping as much of the heat inside as possible.

External wall insulation is a highly advanced layer of rigid insulation that is fixed to the outside of a property’s wall.

This is enforced with a special weatherproof render coat. This layer is where you can choose the type of finish you like from smooth to pebble dash in a variety of colours. You can even have a brick effect finish, which only a trained eye could tell from the real thing.

External wall insulation is suitable for most property types constructed from concrete, stone, steel framed or timber clad.

Using thermal imagery, we can see how much heat is wasted through the walls of an uninsulated house (far left). In the ‘After’ image, you can see that heat loss is cut to a minimum with an insulated home.
