OK not the most exciting topic of discussion I admit!
I've just about finished insulating the inside of the house and next step is the vapour barrier layer, which is also going to be the airtightness layer.
Big range of stuff on offer from 150 to 1000 gauge, big range of prices too.
Are any materials better than others when it comes to getting them stuck together?
Anybody care to share what they've used? Don't want to spend hours looking this up if I can avoid it
