Hi guys,

Just a quick question...

Just rennovating my house and noticed that the original 1/2 brick 1/2 stud walls weren't insulated (stud 1/2 obviously! - studs are 3x2).

I have quite a few sheets of 50mm Kingspan left and wondered if I could use this as oppose to the typical fibreglass rolls usually used?

Any thoughts?

Cheers

are you trying to achieve thermal or acoustic?

[big john 1983]

One wall is adjacent to the bathroom, therefore I guess acoustic would be better, the other is next to the office, so either or really.

Kingspan would obviously thermally insulate, but what are it's acoustic properties like compared to fibreglass and rockwool?

its acoustic properties are quite poor i think compared to rockwool but thermally it is alot better

Many thanks to your response.

I do want to acoustically insulate, as I certainly don't want to hear people letting rip on the pot! and I can see it's obvious advantages...but would I gain anything from thermally insulating as I assume the house would be at an even temperature and heat losses would only be through external walls?

Cheers

thermally you only gain if there you are onl heating a few rooms like it the rads are turned off in other rooms but no real advantage. It is normal to se 25mm acoustic mineral wool in stud now and i would then use 15mm sound block maybe even 2x layers in bathroom 1 of sound block then a finish layer which would depend on the finish ie MR plasterboard for skim or marmox/wedi board for tile
