Nismo280zEd Posted September 25, 2005 Share Posted September 25, 2005 So i did some searches, came up with nothing on insulating heat inside the car. I know we had a thread before about vibration and sound dampening, but i do not recall any dealing with heat disipation and blocking radiant heat. I'm mainly looking at two options. Putting down a physical radiant barrier (RBS) or spraying down a barrier. Does anybody have first hand information? previously i used house carpet foambacking with al, worked pretty good, but on long trips got hot, and it absorbed water which i'm trying to get away from. I'm going to install boat (waterproof) carpet and want everything to be waterproof on the floor. -Ed Quote Link to comment Share on other sites More sharing options...
zgeezer Posted September 25, 2005 Share Posted September 25, 2005 There are a number of commercial products that spray on as a lightweight coating that contain hollow ceramic spheres and claim up to R10-15, which is a measure of the resistance to heat transfer.... or something like that. Do a google search on ceramic insulation coatings or look at this site for one of many products. http://www.cerama-tech-int.com/Index.html Wish you luck. g Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted September 28, 2005 Author Share Posted September 28, 2005 I think i'm just gonna rivet in an AL heat shield under the car. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 28, 2005 Share Posted September 28, 2005 I used the plastic bubble wrap which is encased in aluminum foil on both sides and laid it down on the floors and tunnel under the carpet. Works great...had zero heat issues. Pics on my website http://tim240z.iwarp.com/photo5.html Quote Link to comment Share on other sites More sharing options...

Tim240z Posted September 28, 2005 Share Posted September 28, 2005 I ordered a roll from McMAster Carr, but I noticed that Home Depot also has it. I just cut to shape and used aerosol adhesive to keep it against the floorboards. Quote Link to comment Share on other sites More sharing options...

spotfitz Posted September 28, 2005 Share Posted September 28, 2005 I am actually in the process of this right now. After alot of research I had found there are several choices for sound and heat barriers. The price of some are outrageous. They ranged from $1-$10+ per sq.ft. Yes, some of the higher priced ones do better then some of the cheaper ones, but not enough to justify the cost. I used a product that was only about $1 sq.ft. that I need to use spray adhesive with, but the product was almost as good as the high dollar stuff for 1/5th the cost even after the $13 cans of adhesive. It looks just like what Tim used on his Z. Tim, how much was yours per ft.? My back half is done now and I'm now stripping the tar from hell off the trans. tunnel. I will then strip the paint and por-15 the floor boards, tunnel and put the same material on them. The stuff is easy to work with and form to compound curves. Aluminum taping all the seams was recommended, but if the seams are tight I don't feel there is a need for it, except possibly for radiant heat. On the tunnel and parts of the floor board around the exhaust area I will be taping. http://album.hybridz.org/showgallery.php?cat=500&ppuser=7958 Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 28, 2005 Share Posted September 28, 2005 I think I paid $25 for a 25 foot x 3 foot roll. I used the aluminum tape at the seams. It was a very inexpensive job. I think I saw it near the plumbing isles at HD.... Quote Link to comment Share on other sites More sharing options...
A. G. Olphart Posted September 28, 2005 Share Posted September 28, 2005 Tim, does the bubble stuff have much in the way of sound deadening characteristics? Quote Link to comment Share on other sites More sharing options...

Tim240z Posted September 28, 2005 Share Posted September 28, 2005 That's the stuff! YEs it does dampen sound...likely not as well as Dynamat and products designed specifically for that purpose, but well enough IMHO. Quote Link to comment Share on other sites More sharing options...
