Rubbers for isolating double walls

[mel_sls]

Hi everyone,

I am new here and this is my very first post. I've been reading the forum for a while already and I've found a lot of posts here very useful. I normally just need to search for something that I want to know and the answer is always just right there. The reason i am posting this thread is that I just can't find anything on this topic anywhere. (or I just don't know the right keyword to search?)

I have a question about isolating the double walls in my project studio that I'm trying to build. The double walls are between the tracking room and the control room with a window and two doors. My problem here is that I need to have some rubbers to seal up the gap of the window and the doors between the double walls. I've asked around where I can get those rubber and the only place I could find is here:

The product's price is a little pricy and I would really appreicate if someone here can tell me if there any alternative options I can use besides this. Also, please let me know where I can get them.

Thank you.

Welcome Mel!

I'm not the expert in this, but I believe in de-coupling the walls from ceiling / floors. I just left air (the more the better, but obviously this comes with a space reduction price) between walls. I used an extremely dense industrial rubber underneath the bottom plate of the walls and between the plate on top and the ceiling joists. not sure if that makes sense to you....but hopefully.

Also, we have a studio construction forum on GS. You might pose your question over there, or perhaps the moderator would move it for you. You'll probably get better answers than mine over there.

Oh, and the industrial rubber was maybe 3/8 thick or so and worked out excellent in decoupling the walls from the foundation/ceiling. (I didn't cut the concrete though...)

Ahhhh...just read your post a little deeper. I see what you're after. I think with a creative carpenter, you could still decouple with some industrial rubber, but the product you linked looks pretty cool for that.

Hi Mel,

I don't think the link you provided shows the right material - you should be looking for some open cell rubber, like neoprene. put that in the gap before you install the window (fill the entire gap). to seal it you could use non hardening silicone (outside surface).

hope this helps

Thanks for both of your advices. However, do you know where I can get those materials? My main problem is that I just can't find anywhere that sells them.

Hey Mel, you might want to check out John Sayer's studio design forum.

You can get Rubbers from machines in most public toilets.
Sorry, just read your title that way...

depending on the weight of the wall and ceiling construction - you can use a layer of neoprene, sorbthane, sylomer, etc. a medium-to-heavy weight rubber strip which compresses no more than 50% when loaded will work since you're not using it to seal, you're using it to decouple the frames from the floor and/or ceiling. as you add your mass layers you'll begin the sealing process with backer rod and caulk.

you can find these products online although shopping around will be important as prices vary for products and shipping.

I am missing something here. What gap are you trying to seal? There is always a little gap left to avoid coupling. The drawings here under construction, windows and doors, show this. Some ideas for this gap are shown here. Or are we talking about some other gap?
