Cavity Wall Filling

Post by Ashers »

Was wondering if anyone has had this done?

I seem to be losing heat through my walls and they are cold to the touch, so have thought have this.

What do people think?

Yep, got it done (and the loft) a couple of years back. Heat used to vanish as soon as the heating went off. Now, not so.

Do a bit of homework and find out who is offering the best deal/grant. Should pay back in a few years and keep you warmer in the meantime.

Insulatation

Post by SamD »

Some info gleaned when doing own research last year that may be of help:

house age: building regulations mean that houses built between 1930 and 1976 have cavity walls;
(unfort, mine's 1923 so no gap); anything after 1976 should already have wall insulation

subsidy: energy supplier and council may contribute to cost; example blurb from British Gas (BG):
householder investing in home insulation from BG may receive rebate of £125 from local authority;
BG customer installation price = £225 for cavity and £249 for full loft insulation;
BG projected energy bill savings = £110 a year with cavity wall and £145 with loft insulation.

I read somewhere that only houses built in last 10 years have cavity wall filling.

I live in a small block of flats and we have recently had our cavity walls filled with the help of a grant, we had to pay £175 each on top.

It was sold to us by someone saying that we would notice this difference in cooler in the summer and warmer in the winter. Personally I haven't noticed anything though. Will reserve full judgement for when the cold months come along.

Is a good idea, if you need it.........

I have always bought older properties, cold in summer, and warm in winter :wink:

moving soon to a house built in 1930 - but only single wall (no cavity).

Anyone any experience of (expensive) solid wall insulation?

Aiming to be there 20 years, so prepared for a long pay back.

House also has a back boiler, so preparing myself for a 2nd mortgage for the gas bill :shock:

yes, typical 30s rendering...from the survey

The walls which are approximately 225mm (9'') thick, are built of rendered masonry and appear to be of solid construction.

The walls are in good structural condition with no significant defects apparent. The render is in good order. We found no signs of rising or penetrating damp in the property and the replacement damp-proof course appears fully effective.

I'm leaning more and more that way I think, obviously going to be expensive, as the back boiler is behind the gas fire in the dining room, and the new boiler will need to be re-sited to the kitchen if there is space.

Would you go combi, or keep the cold water tank and hot water cylinder with a separate immersion? Much difference in price?

Any idea how old the back-boiler is? I would guess it is quite old, and possibly very expensive to fix when it breaks down in the middle (or at the beginning) of a cold snap :wink:

I would guess combi would be cheaper to run as it would only heat the water that you use. Also it means no water tank, so more storage...

I believe it is pretty ancient. I do know it is at least safe, as carbon monoxide escaping can be a problem with the open flue, had all that checked in pre-purchase checks.

Apparently it is still legal to replace like with like and get another back boiler - but would be madness unless it is very cheap, due to it being very inefficient.
