Soundproofing Sill Insulation

[elikaufman]

Hello!

I am planning to build an interior wall to divide a room. I've never done it before. I'd like it to be reasonably soundproof (one room will be our bedroom, the other a children's room). I'm thinking of using 45x95 wooden studs with double drywall and fiberglass insulation.

When reading various construction descriptions, it is generally recommended to have a sealing strip or rubber mat between the bottom plate, top plate, and wall studs, and the floor, ceiling, and walls, to optimize soundproofing. However, I'm having difficulty finding a product in hardware stores that would suit. Could this be something? https://www.bauhaus.se/grundpapp-tecca-remsa-yep-2500-syll-fotplat-25cmx10m

or are there other tips? Note it has to be available in stores, as I don't have time to order...

thanks in advance!

Or maybe cut out something like this? https://www.biltema.se/bil---mc/bil...ggspackningar/gummiduk-250-x-300mm-2000017978

Hello!

I'm going to frame an interior wall to divide a room. I've never done it before. I would like it to be reasonably soundproof (one room will be our bedroom, the other a children's room). I'm thinking of using wood studs 45x95 with double plasterboard and fiberglass insulation.

When reading various construction descriptions, it's usually recommended to have sealing strips or rubber mats between the bottom sill, header plate, and wall studs, and the floor, ceiling, and walls to optimize soundproofing.

You can use a regular adhesive rubber strip underneath if you're using wood studs. Or just use regular silicone strips.
If you're using metal studs, use skp around.

A tip here is that if you're doing 2 layers per side, which I assume due to the sound issue, you can leave 5 mm around the first layer and seal tightly with latex caulking before applying the second layer. It works both with and without the previous solutions with strips/skp.

You can use a regular tape rubber strip underneath if you use a wooden frame. Or just squeeze regular silicone strips. If you use metal studs, use SKP all around.

A tip here is if you're using 2 layers per side, which I assume due to the sound issue, you can leave 5 mm all around on the first layer and seal tightly with latex caulk before slapping on the second layer. It works with and without the previous solution of strips/SKP.

Rubber strip - if I had searched for that, I would have found plenty. I feel stupid. Now I used Biltema's 1mm rubber mat that I cut instead - hope it will work reasonably well at least.

Best regards, Eli

Rubber strip - if I had searched for that I would have found a lot. Feel stupid. Now it became Biltema's 1mm rubber mat that I cut to size instead - hope it will work reasonably well anyway.

Best regards, Eli

You want it tight between the stud and the floor/ceiling/wall. How is really irrelevant.
