Cavity Walls?

Postby Fallguy » Sat Nov 28, 2009 10:35 pm

Just wondering how you can tell whether you have cavity walls? Our house was built about 17 years ago, and seems to be brick on the outside and partition on the inside (and not really that thick).

Given we have economy 7 storage heaters, any reduction in heating requirement is a significant money saver - I have already double insulated the loft to 500mm depth and had UPVC 25mm double glazing and doors installed last year.

Not sure if building regulations required CWI 17 years ago but you will be able to see if it has been done since by looking for the array of filled in holes they use to pump the stuff in.

Our house is 10 years old and has been done - My folks was done about 15 years ago and make a hell of a difference.

We had our done about 2 years ago and definitely made a difference - not just in reducing heating, it made the house cooler in summer too. It works both ways :lol:

That's a good idea, I'll have a look for holes in the wall.

I'm just wondering if some houses can have cavity wall insulation, if say the cavity is too small or the walls are too thin. Our house is a pretty cheap built end terrace.
