My idea for sealing between spaced walls.

What are your thoughts on this Idea? I am considering ways to seal between the walls at my double door openings and control room windows. I have anywhere from a 2 to 3.5 inch gap between the walls. I was simply going to cover them with fabric so they would breath a bit and not make the doors so hard to open do to a vacuum forming between them. But I got to thinking about folks poking their fingers though the fabric etc. So here is my idea: What if I were to get some thin paneling (1/8 inch thick or so) , enough to cover the openings, but only attach it firm to one side letting it cantilever to the other side, then put a bead of acoustic caulk (or silicon) to lightly adhere the unattached side to allow the walls to not be tightly bridged. I could even put a spacer of 1/8 in or so on the hard fastened side to provide a small space on the free side to where it is only resting on the adhesive. If you can picture it, do you think this will compromise things too much by causing considerable flanking? I'd appreciate the thoughts. Tom

I don't think I'd worry about the fabric. Have you seen what Aaronw has done with fabric on his project? His sound lock went from this... ...to this... ...to this... --Keith :mrgreen:

That looks cool! I did not explain my question adequately though, my situation is pretty different. I have my 2 single sided walls with the air gap between them. When opening the doors you can see between the walls seeing the studs and insulation. I just want to hide the gap. I have seen people staple burlap or whatever bridging the gap, but I was trying to put something more durable and solid if possible. I was thinking if I only hard attached it on one side but used a few dots of silicone on the opposite side to keep it from flopping, maybe it would work. Tom

I know that I've seen photographs of that situation before, where fabric was used to cover the gap. I can't remember where though. --Keith

Thanks Steve! That is exactly what I was thinking about! I see it has been done before, no surprise there! Thanks again. Tom
