My fellow Blasters, a person from our energy supplier is coming in a couple of weeks to survey our domiciliary edifice with a view to installing cavity wall insulation. Over time I have heard various stories, good and bad, about having it done, house filled with fumes, damp walls, etc. Would anyone with experiences of this procedure and its effects, good and bad, care to share them, please? Thank you. N.Z.
We had the fluffy dust stuff pumped into our walls 2 years ago. The change in room temp was truly amazing in our 1970s house and it seems to have cured 2 damp patches where condensation got at the walls. I think it cost us £25 and the Welsh grant covered the rest. Not sure if it is available over the border in england, though.
When I built my house I looked at all sorts of wall insulation and ended up putting in the fibre glass batts in the walls as well as the ceilings. I then nailed the silver foil type material to all the wooden battens.
Best thing I ever did - warmth, quietness, sound deadening.
Compared to other houses it is so quiet it's not funny.
I must admit doing it when the house is being built makes it a lot easier !
So, IMHO, any wall insulation is good from my point of view.
Had ours filled with foam a bit back. No problems except we ended up with a couple of cubic metres of solid foam in the loft (and some in the meter boxes) where there were holes between the cavity and the space. Seemed to bring the bills down a bit but difficult to compare.
(And the noise of the drilling is horrendous while it lasts, but they do warn you about it).
Sorry about the confusion, folks, i.e. two identical threads on the same subject! However, as I mentioned in #1 above, I now have someone coming to give the place a look-over, and already I have found out that there are more fillings being used in the cavities (foam, beads, flock, etc.) than I knew about. So, any more input welcome, and thanks to those who have taken time and effort so far. N.Z.
