Cavity wall insulation

Is your home well insulated? Are you sure?

Cavity wall insulation

Remarkably, about one third of all the heat lost from homes disappears straight through the walls. There may be security in bricks and mortar, but there are a lot of heat-sucking cavities too!

Don't worry, cavity wall insulation grants are available to help you shore up the cavity and create a thermal barrier which keeps a lot more of the heat in where it belongs - helping to keep your house cosy. Providing you're not a council tenant, or part of a housing scheme - (they've got their own grants available) you could well be eligible for free cavity wall insulation.

Do you really need cavity wall insulation?

If your home was built between 1924 and 1982, then the answer is probably going to be a yes.

A cavity wall is made of two layers of masonry bricks with a gap of at least 50mm in between. The cavity wall design with masonry bricks was chosen for its damp-proofing properties, but doesn't provide great insulation. But it wasn't until the early eighties that buildings regulations specified that properties with a cavity should be filled. So if your home was built between those dates, you really should take advantage of the cavity wall insulation grants that may well be due to you.

The cavity wall insulation process

First of all, do you have cavity walls? There's an easy way to tell. Take a look at the external brickwork on your home. If all the bricks run in the same direction, without any half bricks, then it is very likely a cavity wall. (This is called stretcher bond brickwork.)

Cavity wall insulation will prevent up to 35% of heat escaping through your walls. In monetary terms, you could be looking at savings of up to £145 a year for heating a typical family home.

Cavity wall insulation is a very quick process - and straightforward too. It'll just take two or three hours to insulate a typical family home. The insulation process needs to be carried out by an expert - and if you're eligible for one of the cavity wall insulation grants, you'll get an approved professional to do the job.

They bore a series of small holes into the mortar around the brickwork and inject the insulating material (usually glass fibre, also known as shredded mineral wool, or insulating beads) through the halls where it expands to fill the cavity. When it's all done, they'll patch up the holes for a nice neat finish.
