Hi guys,

More drama from the new property...

I need to insulate my loft. As we don't have a loft hatch, father-in-law


Hi.

Unlined slate roofs let in quite a bit of water, as you say. To dry
out they must also let in the wind. You therefore should not be using
any type of insulation that doesnt let the wind go through it, such as
vapour lined boards. Trap water like that and you've got real
problems.

Of course this limits how much insulation value you can get in there,
but thats secondary to the roof staying up.

I could take a guess at loose fibreglass being suitable, but being
unclear about the construction details it would only be a guess.
Anything more substantial would need to be applied to the interior.
But, even 4" or 6" of fibreglass makes a big difference.
