Working out your homes wall type

Solid wall image

Covered/rendered walls

If your home has covered brickwork, you can measure the width of the walls surrounding the windows and doors.

Solid walls will usually be less than 260mm, if your walls are wider they will probably have cavities.

Solid walls

If your home has an irregular brick pattern with both long and short edges of the bricks on show, usually means it has solid walls.

Cavity wall image

Cavity Walls

If your home has a regular brick pattern, showing the long edge of the brick only, usually means you have a cavity.

Here's how we'll install it for you

Your solid wall insulation will be tailor-made for your home. We'll arrange for one of our Energy Experts to survey your property. They'll suggest the appropriate solid wall insulation and you choose the colour for the final render.

We'll install it in these simple steps - in around three weeks:

one-logo

We'll put scaffolding on the outside of your home, removing any fixtures as we go.

two-logo

We'll apply your insulation with the colour and texture of your choice.

three-logo

We'll then put back any fixtures, remove the scaffold, leaving you with a new, warmer home that looks great.

Here's what some of our customers had to say:

"I can't praise the workmen enough, they were polite and considerate to us and our home"

J. Stevens

"We had timber cladding with not very good insulation behind it, this was all replaced with this new render insulation and it makes our house look so much better"

N. Daley

"Since I have had the External Wall Insulation done I have noticed that every room is a lot warmer, I can definitely feel the difference"
