 |
|
Working on my headliner on tin top. Looking for suggestions for the stick on rubber sound proofing to help with the rattles of the body but also looking for some insulation ideas to stuff in up above the headliner. I’ll be using 1/8” Baltic birth for the headliner itself.

The sticky rubber product is called Alubutyl. There are a number of different brands but they are all the same besides thickness. All it is is a thin layer of aluminum over a butyl backing. I got the amazon type and it applied great and was a lot cheaper than the other brands. When applying it, you only need to cover a small area on each flat panel section, not the entire surface and not the rigid sections. All it does is add some mass to the panels to stop them from vibrating. Use a small plastic roller to apply it.
Here is mine. I probably used a bit more than I had to but I had extra material anyway.
I didn't do any other insulation up there yet but was planning on sticking some felt up there with adhesive to combat condensation.

Thanks! Another idea regarding headliner material - I used matchstick shades and vinyl flooring transition strips, super easy to install and remove if need be. Gives you just a tiny bit of extra headroom too which I definitely appreciate. Just food for thought.

I’ve used the low-E (EZ cool) insulation on a few vehicles and it works well , it’s thin, doesn’t absorb water, insulates and noise dampening. It’s been popular with the hot rod community for decades. I have two layers in the roof, walls, etc
