Many thanks!

Thanks for that. Unfortunately the external wall is not cavity - just single brick (freezing) so maybe in that case cheap fencing wouldn't be hardy enough and I probably do need air gap on the external 1!?? Drat!

Wanting to insulate gable /end walls (1 external and 1 connected to neighbour). If building a stud frame, can you use rough sawn treated timber (meant for fencing) as that's is all I can see that's around 100 x 20mm wide. Or does it need to be C16? There's loads of 60mm C16 stuff lying...

Thanks for replies. Cabby, rafters are 125mm deep so I had remembered about need for gap. Jack, it was actually to keep outside noise out but yes there will be music too! I'd heard that Kingspan isn't that great so will look into that hybrid ins. Cheers!

Does anyone know the most suitable insulation (for attic rafters) to achieve warmth and some soundproofing? I can add timber if necessary but aiming for about 75mm max thickness and it can't be the usual, very heavy lead weight soundproofing. So I was thinking about a combination of 50mm...

About to insulate (between) the rafters of loft and originally intended to just use kingspan but I'd really like some kind of soundproofing as we live in a very noisy area. Would prefer total depth to be no more than around 80mm and as lightweight as possible. So now thinking about 50mm...
