I took out my recliner and side table and put in a wall hugging love seat recliner and am making a tv elevator for behind couch that sits in slide. While waiting for parts to arrive went ahead and removed tv in front cabinet and saw that the foam/heavy mass vinyl insulation had completely fallen off the front cap and was nearly disintegrated. Where can I get the foam/heavy mass vinyl and/or what did you all do to replace the original insulation?
In process of gen quiet box and compartment clean up. Remove old and scraped and cleaned. Major pain. Used 80 mil Noico sound deadener and getting ready to apply Thermolite for sound absorption. There are closed cell foam insulation products you should look at for interior applications. I would definitely apply a deadener first
Yes, definitely will add something like Noico or heavy mass vinyl. I was wondering why my coach seemed to have so much more wind noise. Thought it might just be the solar panels making it noisier, but after seeing behind the front cabinets, I now know it was because the foam/heavy mass vinyl had come completely undone from front cap. Why did you pick Thermolite, and where and for how much did you get it?
Recommended by MOT. If I was going to do inside I would seriously consider a thicker foam type sound absorber over a deadner. It can get pretty pricey though. Thermolite is only 1/4" thick
I used 1" thick closed cell foam and glued it in place-- been there 1-1/2 years seems to be working fine. I was more worried about condensation running down onto the plywood in the top cabinet and rotting it out.

How did the closed cell do for sound attenuation? Was it as quiet as the old stuff or about the same?
I couldn't tell any difference in noise level--BUT I'm hard hearing so I'm probably not the best Judge
and my loan insulation was like what was mentioned above-- it had all fallen down and was a general mess

I use the sound in there first and then a foam design for under the hood of cars. It did cut down on the amount of noise but I still have lots of wind noise from the door and the zip tie awning so there's still plenty of noise there. I also have two trucker cellular antennas mounted on springs right above the front cap and in the windows things bounce back and forth making a lot of racket. It did cut down on that sum but it's still there. The other thing you can use is sounddown insulation. There's two kinds one that has a thin piece of rubber dampener in between foam and a radiant heat foil on one side or without that rubber dampener. The rubber dampener adds a lot of weight. Sounddown is expensive, as it's marine grade but well worth the money. I put that in my engine compartment.
This is what I used. Easy to work with, self adhesive, and does a good job for both sound and heat. Plus, relatively cheap.
