Funny you mention about insulation. Are you upgrading and of it to the soundproof stuff? My builder asked me last week what we wanted I'm not sure it's worth the extra cost
Yep
We are using soundproof batts and soundcheck plaster just around the master and ensuite as we are light sleepers and sick of having to wear ear plugs where we currently are to block out the birds and neighbours etc! Hopefully this combined with the double glazed windows will make a real difference. We honestly can’t wait to find out
Do a search on the forum as many others have already installed these and might be able to shed some light on effectiveness vs cost.
