Hello all.

Montes going in for body work soon. Anyone have any good brands of insulation that they use? I want to insulate my new doors and under the carpets.

 

I've used Thermotec Thermoguard when working on a buddy's old hot rod. Very happy with the results for a 'do everything' kind of mat. I've also done old school dynamat in the long past on many sound system cars, but if course it has more limited function.

The big thing you need to decide first is what youre insulating for:
-heat
-sound
-panel vibration
-adding cushion feel to floor carpet

Secondly is how much thickness you have to work with (some of the stuff can get pretty thick and cause issues if you're reinstalling stock carpet).

Third is how much weight you can live with. If you're shooting for luxury car quiet, you can easily add hundreds of pounds in insulation. Some people dont care, but it will hurt performance and fuel economy.

 

My primary goal is to reduce vibration and sound, so the doors click shut nice and smooth without banging around and so the Monte doesnt vibrate down the highway. It's got a tuned 350 in it so gas milage isnt a concen at this point lol.
