Alternative to spray foam? 15 May 2022 at 1:40PM in Green & ethical MoneySaving 6 replies 121 views

Hi

So I've seen this 

https://www.mortgagestrategy.co.uk/news/spray-foam-insulation-leaves-250000-homes-in-mortgage-limbo/

So, I really wouldn't want any spray foam insulation. What's a better form of insulation? One that doesn't have other issues down the line? 

Ectophile

For most people, ordinary loft insulation on the floor of the loft.  There's no need for the spray stuff all over the inside of the roof.

Lofts don't need to be warm, and they do need to be ventilated.

As Ectophile says, cheapest and simplest is glass wool (or similar), supplied in rolls then laid flat in the loft space between and over the joists. This does make it difficult to use that space for anything else.

Not on purpose anyway. I can't even see your reply to that thread 

How would we do it in such a way that you can still use said space?

Also how about the roof itself? My parent's house has an attic, and there's a little bit above it that we don't use

Your other thread is here. I deleted my reply from that thread and re-posted in this one.

You can use loft legs, as illustrated in this article. This lets you board over insulation without compressing it (compressing it removes the air and makes it useless).

Or you could use rigid insulating board instead, far more expensive but with a higher insulating value for a given thickness.

Also how about the roof itself? My parent's house has an attic, and there's a little bit above it that we don't use 

You'd normally only insulate the roof in order to provide a "warm loft", and you'd use those expensive rigid boards.

Thanks for that. I can't delete that thread myself, and you can't add a note when reporting, so I've edited the OP to ask mods if they could merge it given someone else has replied there

I'll have to have a look into that. Thanks

I believe you could change the title of the other thread - perhaps to include "Duplicate : please do not post"
