Dynamat installation
Who has put Dynamat in their midyear conv? I will be replacing my carpet this winter and instead of the jute padding under the carpet, how practical would it be too use Dynamat or an equal product? I do not have A/C, so that does not need to be considered. Would it serve the same purpose as the jute? Would the difference in thickness be an issue? Those of you who have installed it, what difference did you notice? Any valuable tips/tricks learned? Many thanks!

I started with the heat barrier from Wilcox. I didnt like it at all (nothing against Wilcox). I ended up ripping it out and using just Dynamat and Carpet. Mine is convertible so noise was not a consideration but I still wanted it to feel and sound solid. Im very happy with the results and I do not notice any excessive heat. Keep in mind that Dynamat is mostly for sound and not heat, although I'm convinced it helps with the heat too.

I used Reflectix from Lowe's. As you know the 65 is a convertible with sidepipes so I wasn't concerned with noise either. I used it to reduce interior heat. I'm happy with the results for the money. It's much cheaper than Dynamat.

I can't say I noticed any noise reduction. I was really just trying to reduce the heat from the floor and it did that.
I used a 3M contact spray glue for the Reflectix and the carpet. Don't remember which one. I picked it up at Lowe's as well. I will tell you are in for a real treat replacing the carpet. Be sure to include plenty of beer when you go shopping for supplies!

I put Dyna-Mat inside my '60 from the beneath the windshield frame, down the inside of the firewall, along the floor and behind the seats. I then placed the carpet directly over the top of it. What a difference in sound and heat abatement. And yes you get what you pay for. A side benefit is that it seals all of the little cracks and pin holes that these old cars have. My car is amazingly dry in a rain storm. It just feels more solid and won't absorb water like jute will.

Does anyone know how much more weight is added to the car when installing Dynamat Insulation in a Coupe? I have heard that a complete installation to include the doors and roof adds another 100 plus pounds. Can anyone verify this? Not trying to change the thread but looking for the best / lightest, heat / sound installation, if there is such a product.

Thermotec
I used a product called ThermoTec. It is much like Dynamat but much more inexpensive. I used it on my floor, roof, doors throughout the interior of the car. It maybe weighed 25 lbs total. My black on black coupe stays cold and quiet (quiet as you can be with sidepipes) in Florida. I do have a Vintage Air A/C system. Jerry

I Used Dynamat Extreme - The Foil Backed Dynamat.......
in our 1966 AC Convertible, and it not only reduced heat inside the car, but some road noise as well. By the way, most car stereo shops carry Dynamat at prices way below what the car part catalogs charge.

c66vet, Dynamat Extreme, 9 pieces, 18 x 32 ea. 36sq. ft. weight 23lbs. That covers a large area, more than what I think would be needed in a midyear. Dennis
