Good afternoon
We’re considering insulating our upstairs rooms properly, by insulating the loft space directly above these rooms.
This is for a combination of both heat loss and sound.
We live in a relatively new build property (2006) which has soffits around the whole expanse of the loft to allow the loft to breathe. The loft itself has not been converted and has the usual timber trusses supporting the roof.
We're looking to use Rockwool rw5 in between the joists on the floor of the loft:-
http://www.rockwool.co.uk/products/...(formerly known as RWA45, RW3, RW4, RW5, RW6)
Is this product ok to use in a loft without any insulation/plasterboard on top of it (for issues like condensation risk etc)?
Also, what depth can we use - can we only use this up to the height of the floor joists, or can we go higher?
