jetro 5,349 Posted February 28, 2017 Report Share Posted February 28, 2017 We had ours done last October, acttic and cavity. Have to say we do notice the difference. Quicker and cheaper to heat, and holds the heat a lot better. Didn't notice any problems with dampness or condensation. Atb j Quote Link to post Share on other sites

Greyman 28,817 Posted February 28, 2017 Report Share Posted February 28, 2017 As a plasterer I,m dealing with many houses experiencing black mould after a few years of having there cavity,s filled I,ve spent years on building sites being taught the importance of keeping the cavity clean as the air flow is what stops the moisture crossing from the outer skin to the inner skin and yet now people are filling the cavity with recycled wool and cloth that gets damp and bridges the gap a total no no as far as I,m concerned and in years to come there will be firms springing up charging you to remove it 9 Quote Link to post Share on other sites
Fat-Ferret 857 Posted February 28, 2017 Report Share Posted February 28, 2017 What about the beading they do in the walls? I also thought that all new houses were cavity filled as standard Quote Link to post Share on other sites
Nik_B 3,790 Posted February 28, 2017 Report Share Posted February 28, 2017 Houses are built with cavity for a reason, to stop damp ingressing through the wall. I agree 100% and also old houses had chimneys and windows that weren't totally sealed like today, it allowed moist air to circulate out of the house. If anyone has sold a house recently and the buyer paid for a home buyers survey you might have been surprised to get told you have rising damp, yet most likely it isn't and they are just detecting moisture on the walls because of poor ventilation. 2 Quote Link to post Share on other sites
Fat-Ferret 857 Posted February 28, 2017 Report Share Posted February 28, 2017 According to tinternet, bonded beading makes it impossible for moisture to reach the inner wall and it goes straight to the foundations Quote Link to post Share on other sites
jetro 5,349 Posted February 28, 2017 Report Share Posted February 28, 2017 Ye got me worried now lol. There was 50mm kingspan in the cavity before it was pumped. Wonder it there more damage than good done. Atb j Quote Link to post Share on other sites
Welsh_red 4,690 Posted February 28, 2017 Report Share Posted February 28, 2017 Im no expert on this so anybody who knows more than me can tell you if im wrong or right . I was told when they pump your cavity full it needs to be completely full for it to have no dampness come through . If there are pockets without it because they havnt filled it properly then those pockets will have the dampness coming through . I assume its the mass condensation in there. I have seen a house in our town have a different thing done to it . I should have enquired at the time just to know but i didnt . They attached what looked like huge insulation boards to the outside of the house and then had some sort of plaster finsihing it . Obviosuly will only work if you have available soffet board space .Might be worth looking in to Quote Link to post Share on other sites
baz 464 Posted February 28, 2017 Report Share Posted February 28, 2017 A definite no no for me, as been said it's just a damp cross over point.... Can't believe there still knocking houses up with cavity bats,instead of the kingspan stuff Quote Link to post Share on other sites
The one 8,493 Posted March 1, 2017 Report Share Posted March 1, 2017 Same here its no for me as my mate was building our porch and side garage on the house i asked about getting cavity insulation as there wasn't that much left he replied i dont believe in it the cavitys there to do a job why fill it up Quote Link to post Share on other sites
whiteracer 258 Posted March 1, 2017 Author Report Share Posted March 1, 2017 Cheers for the replies lads, I was in two minds myself but think I ll give it a miss now ?? Quote Link to post Share on other sites
Welsh_red 4,690 Posted March 1, 2017 Report Share Posted March 1, 2017 When we've done new build houses weve used kingspan insulation boards that are held to the inside course . There is wall ties that attach the outside and inside courses and we always try to keep as much cement from falling on them because they act as a bridge for water if their covered in cement . Few days after laying the blocks so the cement is all dry we (usually me) is up above the wall with a length of battern and a torch checking if any cement is dried on the metal . If it is I use the battern to tap it off. I'd be pissed off if someone came and filled it all with something 3 Quote Link to post Share on other sites
mandog 37 Posted March 1, 2017 Report Share Posted March 1, 2017 Damp is not going to travel through the foam insulation is it. Quote Link to post Share on other sites
Greyman 28,817 Posted March 1, 2017 Report Share Posted March 1, 2017 (edited) Damp is not going to travel through the foam insulation is it.wow a scientist, new houses have a layer of foam attached to the inner skin but the cavity is wider to allow an air gap, in older houses the cavity is a bit narrower and some smart ass sales man comes around and tells you it's best to insulate, you then pay him an arm and leg and in return he sends round a van with a pump a couple of tons of recycled rags and a pair of retards, they then drill holes all over your house and pump in the shitty mess stick a bit of shit in the holes and gel on, over time the recycled rags get wetter and heavier slowly sinking to the bottom of the house therefore causing a soggy wet cavity that is bridging in the damp by the bucket load, I think that's the best I can do without a blackboard and chalk Edited March 1, 2017 by Greyman 2 Quote Link to post Share on other sites
