If your walls are not insulated,
about a third of your heat is lost
through them. Across the UK, that
adds up to about £860 million worth
of wasted heat! Cavity Wall Insulation Quick, easy and effective for a lifetime saving
 Mind the gap, it could be costing you dearly
If your home was built from the 1920’s onwards,
there’s a good chance that the external walls have
a cavity. In effect your walls are built in two layers
with a gap in between them.
It’s important to fill this cavity because around
a third of all heat lost out of your home will leave
via its walls. So not only will cavity wall insulation
save you energy and money, it will also help to keep
your home more comfortable. For an example of
the cost savings available to you, an average three
bedroom, gas heated, semi-detached home will save
you about £160 per year. Therefore payback on your
investment should take just under a year and a half.
Is your home suitable for cavity wall insulation?
If your walls have unfilled cavities that are at least 50mm in width and the masonry
and brickwork are in sound condition, it’s probable your home (and bank balance!)
can benefit from the installation of cavity wall insulation.
It works by forming a barrier to escaping heat. In effect, it stores heat in the ‘inner skin’
of your walls and radiates it back into your living areas, giving you a much more constant
temperature throughout, while enabling you to turn down your heating.
Note that if your home was built in the last decade or so, then it’s likely to already
have cavity wall insulation.
A job for the professionals
Installing cavity wall insulation is not something you can do yourself so have
a registered installer undertake this work for you.
Generally this will involve an initial survey, with attention being paid to air vents,
gas appliances and suspended floors, all of which will need to have adequate ventilation.
The additional benefits of cavity wall insulation
Cavity wall insulation offers you and your home a number of benefits over and above
its energy saving attributes. These include reducing condensation in problem external
walls and eliminating draughty gaps around poorly fitting door and window frames.
