Cabin Insulation Material

[okflyer]

I have been wondering what people are using these days for insulation behind the sidepanels and above the headliner. Last time I used hot water tank insulation wrap that worked quite well but its worn out and ready for something new.

A search for "soundproofing" will give good results.

Thanks. Looks like Super Soundproofing is the way to go.

Sound - Ex is another good product. I used it and was very satisfied.

I found it a lot cheaper and easier to just buy a better headset.

There is a lot of truth in that.
After installing good door seals, there isn't much one can do about noise in these things other than
a good headset.
These airplanes are noisy, even with the best soundproofing materials.

Its actually not so much the soundproofing as the insulation for cold weather flying I'm looking for. The water tank silver wrap material was working pretty good but was disintegrating after 15 years or so.

This was my answer to cold weather flying

I didnt buy it last year as the winter wasnt that cold for us.


For keeping the plane warm, I've found keeping the draft out to be the most effective.
This can be non-trivial when it comes to door seals.
Don't forget the whole tailcone. Not just behind the access panel but the section behind the headliner too.
And the wing roots.
and the landing gear
and the windscreen
and the inspection plates..

wow, that jacket is starting to look cheap

One of the fellows up at my airport flys a big Cessna twin for a ranching company and they just had it all reinsulated with some kind of black colored foam that is approved for the job. The pilot said it was like a new airplane. He said that temperature and sound were both greately improved.

Good point blueldr...It needs to be approved. Many products are not and may not be good in a fire and may in fact incapacitate. I used Mooney sound proofing back in the late 80's for mine and it is still holding. Probably cannot get that kind of adhesive anymore.

Selkirk Aviation in Idaho sells pre-cut soundproofing kits as well as their fiberglass interior pieces. I haven't tried one (yet).

I see the Sound-Ex kits for the C-170 are $745 from the manufacturer and jumps to over $1000 for the same thing from Aircraft Spruce. I can sew several warm coats together.

I have put two Selkirk interior kits in Cessna 180's. They take quite a bit of trimming and fitting. Having air powered cutting and trimming tools is not a must but sure make the job go faster.

After putting in expensive sound proofing and thicker glass all the way around and all new seals I found little difference in the noise level. As mentioned above, get better headsets. The one thing I did notice was much improved cabin heating, it required less opening of the heater valve and the heating was very even throughout the cabin.
