Firewall Insulation Material??

While I haven't used it on an aircraft, my mechanic used a thin foil insulation material on my car after I experimented with how well it would float. (It didn't). After the interior was all out and treated, he told me this stuff he got at the hardware store was better than the original foam matting. It was about 1/4" thick with foil on both sides and a sort of bubble tape center section. It came prepared with adhesive on one side so you could peel-and-stick. He got it at home depot or lowes or something. He was right, it works, and it was cheap. Not sure what it was, but you might just buy a bit of it at the store and hold it over a candle to see if it fits the bill. -Matt |

Firewall Insulation Material??
What adhesive did you use on this material?
I used a 3m spray adhesive to attach some PVC foam insulation to the firewall of my RV-6 and have had problem after problem with the adhesive releasing. I believe it is heat related.

Firewall Insulation Material??

When burned, PVC releases toxic hydrogen chloride gas. I think I'd prefer to use a more inert and fire-resistant insulator at a firewall. Thanks, Bob K. |

My employer used to manufacture a huge line of floorcovering products which used PVC as a major ingredient. With the right additive package in the PVC, it passed every flame and smoke test required to be installed in residential, commercial, or even healthcare property. I'm sure purpose built PVC insulation sold through major aviation suppliers uses the same additives. KB |
