I want light and sound isolation
Posted: Mon, 2024-Mar-11, 18:47
The room is coming along - see photo. The wood inner structure is done, wood fiber insulation is in place, the rest is on it's way...
I haven't yet decided what to do with the floor. And I'd like to decide before putting up the drywall, in case I decide to do a screed, which might warp the drywall. The existing floor is a slab that's not very level. In one corner I have 4cm difference with the highest point.
I had originally thought of just putting down an underlay underneath a laminate floor. Something like this: https://www.leroymerlin.fr/produits/rev ... 67108.html
But now I'm thinking maybe I should level the floor once and for all. For this I see 2 options:
Option 1 - install a screed (self leveling cement) between 0-4cm. Then follow with the original idea, a thin underlay and laminate floor. This would be a cheaper option with less isolation.
Option 2 - a dry vermiculite screed for leveling, with a layer of something hard, such as OSB on top, then finished with stratified flooring. If you search for fermacell dry screed you'll see what I'm refering to. This is a more expensive option with (I believe) better isolation.
I have two questions:
I would like thermal as well as acoustic isolation. I believe the weakest part in my design is the double glass doors. As I believe that sound isolation is a "weakest link" kind of thing, would the extra sound isolation from option 2 be of any use?
I believe most types of insulation sold for use on floors with thermal and acoustic properties are meant to dampen mainly foot noise between floors. Because in my case I would want to prevent as much flanking as possible escaping the room through the slab (for example drumsets or bass amps sitting on the floor) Would any of these products actually be doing me any good?
