Greetings
I mentioned this in a nother thread but thought it worthy of it's own topic.
When thinking about my drywall on studs inner room construction, I realised that I would be screwing many 'things' to the walls and ceiling. particularly frames for internal acoustic treatment.
As you probably know fixing to drywall is a PITA.
So I've replaced one of the layers of drywall with MDF. not the room facing layer, but the layer behind that to preserve some fire resisitence.
This will mean I can fix things to the walls and ceiling ANYWHERE, and not have to worry about where the studs are ( except for extremely heavy items.
Using MDF as one of the layers will presumably affect the transmission loss in some way. but MDF is denser than standard dywall, and as dense as 'soundbloc' type drywall.
So unless it noticably degrades the TL (transmission loss ) it sounds like a really cool idea. :)
