I am in the final stages of restoration and I am wondering what people are doing to deminish the heat in the interior. I have jet coated the exhaust system and will probably wrap teh header pipes. I will follow the recommendation and seal all of the holes in teh bulk head and floors. But what materials are you using to stop heat transfer? My preference is not to add 1/2" material to the floor if I can help it. I would like something that works well but will not make the interior panels buldge out.
 
Dynamat has made an incredible difference for me, and it has not "bulged" the interior panels. It's about 1/4 inch thick.
There was quite a discussion about a month ago on the forum about the pros and cons of dynamat and other brands, you should look it up.
 
Hi Healeyguy,
Yes, search the forum. This was one of my topics that got a lot of discussion. It came down to two companies. Coolmat and Dynamat. I also used Pegasus heat shield under the stock heat shields and the bottom of the trans tunnel.

Here's a quick photo of what my car looked like with Dynamat.

The previous posts will show more photos.

Good luck, Roger
 
Roger, I'm so disappointed in you. The Dynamat on the driver's side is oriented in the wrong direction. The logo should be facing towards the back. Sloppy work my friend, sloppy!

Roger,

What a great idea... I had just bgun a search for a heatshield for both my BN4 and my MGA 1500... I noted from the Logo on the matting that you purchased is the Extreme Dynamat.

How many rolls did you use and did you also put it on the trans tunnel??

Thanks

Never too cool in the cockpit. If you also turn off the heater valve on the side of the block and open the "Air from Heater Control" along with turning the "Boost Switch "on you will get cool air from the front of the car dumped into the footwells.- /ubbthreads/images/graemlins/yesnod.gif--Keoke- /ubbthreads/images/graemlins/hammer.gif

Hi Ron,

I purchased the largest pack they make.
DYNAMAT XTREME BULK PACK 10455 EXTREME 36 SQ.FT

One pack was enough to do my entire inside. Not the trans tunnel though. I used another product for that.

I found the best place to purchase Dynamat was on ebay.

For under the heat shields and underside of the trans tunnel I used this product:

Photo of the bottom of my transmittion tunnel attached.
Cheers, Roger
 
Roger, A wealth of information... thanks for you recommendations...

Right you are Ron!
Because of the friendly and knowledgeable people here, I was turned on to many products to look into.

There are many things to consider when putting your time and effort into this job. What do you want the product to do?

My main concern for the floor was to make it water tight, seal up any places where hot air can come in. Sound deading was second. Heat shield was last. My understanding is that the heat shield reflective surface should point towards the heat.

Attack heat at the source. I removed all the heat shields under the car and installed the Pegasus heat shield on the entire bottom of the car. Then replaced the factory heat shields back over it. The Pegasus is only as thick as a sheet of fiberglass. So the factory heat shield still has the air space between it and the floor.

Also instead of using jute under the carpet, I used Low-e brand insulation. It has foil on both sides and will not absorb water like jute.

Cheers, Roger
 
Check out Lowes and or Home Depot for heat materials, very thin, cheep, and works well from all accounts.
