Soundproofing/Insulation

plahnk

Hi All,

I am currently restoring a 77 Archer II and seeking recommendations on both soundproofing and insulation. The cavity depth is 1.5 inches so I am considering a combination of the half inch thick Aerotex soundproofing and the one inch thick SoundEx insulation. Any recommendations or observations will be much appreciated.

Thanks,

TJ

TJ;

Both vendors you listed are good.

Years ago, I installed the SoundEx kit in my plane. It definitely helped with both thermal and noise insulation. There is still noise, but you can have a non-headset conversation without shouting. Have not installed Aerotex, but have heard good reviews. I don't think you'll go wrong with either one.

Most of the noise in our planes comes from the engine/propeller and travels through the firewall, but the firewall is one piece of the plane that you should NOT insulate. If a fire breaks out under the cowling, the firewall will get extremely hot. Foam/plastic insulation glued to the firewall will release toxic fumes into the cabin as it melts/burns. You don't need that, you'll already be busy enough.

Thanks, Doc, your input is much appreciated. We are not considering any modifications to the factory installed insulation on the firewall.

Cubs or Sox?

Short answer: I'm more a motorsports/racing fan, but if a Chicago team makes it to the playoffs, I'll root for them!
