I've read that tar-paper is used on the inside floor of the healeys. Was that used on all models? When removeing the carpet on my 64 BJ8, I find under it is jute, but no tar-paper, just the painted floor. Should I have tar-paper there? Where do I get it? Thickness, brand, etc. What is the purpose of it? That area sure does get toasty. What's the take on these two products sold at Moss: (1) "Dynamat Sound Control Super Insulation. 5 mil aluminum top layer combines heat resistance with noise deading." (2)Space-Age Heatshield material foil covered felt, heat and sound deadening material installed under carpets." Would using any of these products with the heat shield help, over using the tar-paper? Is the tar-paper different or like regular Dynamat? Being the carpet will be over whatever I use, I would like to install which ever product would help keep that area cooler. Maybe using it around the transmittion tunel too? <font color="blue"> </font>
 
Would using any of these products with the heat shield help, "over" using the tar-paper? I meant to say, "instead" of using the tar-paper
 
I used the tar paper. Its cheap and you can find some at construction sights or a Home Depot cheap. Doesn't hurt to do it. Interestingly, the EXACT SAME foil heat shield is sold at Home Depot in the water heater section. Twice as much for just over half the price. What Moss and VB sell will only do the floor. I needed more to do the trany cover. That's how I discovered the Home Depot stuff to be exactly the same and it CAME WITH that foil tape. And I have more than enough to re do the floor.

I've used the SUPER DYNOMAT extensively in my 100. I have it on the transmission tunnel both inside and out, on the engine side of the footwells, and under both floormats. I like it because it is easy to apply (sticky-backed) and is not bulky as is lots of the FG-based batting, etc. It also does not absorb or hold moisture and does not deteriorate from the usual oilspray, etc. It is expensive but it doesn't take that much to do the car.
 
/ubbthreads/images/graemlins/iagree.gifMichael, Dynamat covers all the bases. However, I should point out if others go the tar paper route you will require an oil barrier between your carpets and the Tar paper. The heat from the mufflers can cause the tar paper to bleed oil into the carpet. The AL foiled thermal insulation material should perform this function just fine---Keoke
PS; In the "Dynamat Findings"post did you mean 10"X10"???
 
HR; Probably is a good product being as it is ceramic based but I think its price out paces its benefits over the more economical products.--FWIW---Keoke
 
If you are going to enter the car in concours competition, stay with the tar paper. (30 pound roofing felt) If this is not a consideration, "Dynamat Extreme" works very well. It has about 1/4" "rubber" backing that is very sticky. Applied to clean painted metal, it will stick down very tightly with no chance of rust forming under it. Peel & stick, roll it down with a wallpaper roller. It can be painted over to match car colors. It blocks heat & sound very well. Michael put me on to this several years ago & I haven't regretted it. Much better than cheap, loose, bulky paddings.

I used two layers of this on all footwell outside surfaces that didn't have original asbestos covering. It is painted body color & doesn't even show. Inside surfaces got the same treatment. Dynamat is available at most car stereo shops.

Don't forget the "asbestos" heat shield under the floor above the muffler. Healeys don't have to be hot inside.

I am ashamed to admit that I saved this w/out the original source, it could have been on of you, but I think it's good info.

Dynamat findings!!

I was just at a Fry's electronics and got a good look at some Dynamat.

The original is a thick rubber with an adhesive backing, the Extreme is a very soft tar like substance (kind of like a soft version of windshield 'sticky' cord) with a foil backing.

The amazing thing is that the original looks to EXACTLY the same as the sound dampening pads I got from MCM Electronics. And I mean exactly. It even has the same color (light blue) sheet of plastic covering the sticky side. In looking at the Dynamat site, the original speaker kit even uses the exact same size (10'x10'). Well here is were is gets real
interesting...


...the trunk kit is 20 sq ft and cost $99 ($130 suggested retail), the suggested retail for two 10'x10' original squares is $14.99. MCM sells the EXACT same thing for $.99 a square, that's $1.98 for two, and that of course is 13f the cost of Dynamat, or to put it another way, Dynamat is marked up 857ver retail price! Ouch!!

Talk about a markup! And they don't even do any big advertising like Nike. I will take a wild guess and say the owner of that company is raking in the buck big time. Kind of irritating though.

I would highly suggest anyone considering Dynamat, look into the other product. (You can even get it for $.90 if you order 100 or more.) One thing to watch out for though is the shipping. Since the stuff is pretty heavy, shipping is a little steep. I believe I got around 30 square, which ended up costing almost $20 to ship. That still works out
to only about $1.66 a square.

I thought some might find this information useful.

Product name: Sound Deadened
Part Number: 60-120 (just type this number into the search)
Price: .99 (a 10'x10' piece)
 
My car is not concours, just a nicely restored one. Patton, I've used similar products like MCM sells. I've purchased "Q-pads" 12"x12" (6/PKG)from Finishmaster Inc. for about $23.00 However the Q-pads do not have the foil surface. I'm more concerned with heat retarding, than sound barrier folks. I'm assuming that the foil help with the heat? D Russell, "Inside surfaces got the same treatment". 2 layers on the inside surfaces also, or just the outside? Was that the entire floor, front and back plus the transmittion... inside surfaces? Yes, I do have the asbestos heat shield under the floor above the muffler, plus firewall. Thank you so far, everyone who has replied. My next forum question will be, how to get good gas mileage, after adding all the Dynamat. Yup, she's a beauty. Not much on gas mileage, but her floor doesn't rattle and I can wear shoes with thick socks on a hot summers day.
 
Two layers on outside, one inside on entire floor. This material is thin enough to not foul the seat slides or create too much bulk. The weight is not all that much. Dynamat Xtreme weighs about 9 ounces/ sq. ft. It probably wouldn't add more than 10 - 15 pounds to the car. Leave out two gallons of gas & you are about even.

Another thing that really helped was to wrap the header down pipes as a pair with a ceramic heat blanket. Mantaray #101420. https://www.mmrusa.com/HSreflectshield.htm

Wrapping the two pipes as a pair leaves some room inside for air circulation. It can shorten pipe life to tightly wrap the pipes individually. This greatly reduces engine compartment & driver compartment heat.

AusmHly, The asbestos heat shields above the mufflers and in front of the foot wells need additional help.The method I used was to install layers of loose themal insulation in the air space behind the shields. These are cut to the same outline as the shields and are held captive by the shield's mounting screws.---Keoke
 
"The method I used was to install layers of loose themal insulation in the air space behind the shields."

Keoke, what themal insulation product did you use? Where can I get it?

I would like to say Keoke, that when I just logged on here, your name showed as the last person to comment on almost every post shown. Good to have such a knowledgeable person offering input. I certainly appreciate your help. Roger
 
So, what you are saying is it's like being married and never getting the last word? Although I agree it is great to have him and Dave (and many others) to help us learn.
 
Well TH there is an old saying the first Liar don't stand a chance and sometimes its nice to know there is more than one way to skin a cat---Keoke /ubbthreads/images/graemlins/laugh.gif
 
OH AsumHly, the material I used is a double sided AL heat shield material with a loosely packed center core.I won a roll of the material at a car show years ago but I think it is readily available from most accessory shops as it is widely used for under hood applications. --Keoke
 
I have used Dynamat on two restoration project Healey's and love it. It costs approx. $220.00 for a big box of Dynamat at a car stereo shop and this will cover the entire cockpit, transmission tunnel, rear bulkhead,inset door panels (behind the vinyl panels), and the majority of the trunk. The beauty of Dynamat, is it is first known for its sound-deadening effects for modern car stereo systems. It takes the rattle out of metal on metal! When I close the doors or the battery hatch on my BN6 or my 100M, it makes an almost silent thud, instead of a loud rattling ping! For Healey owners, Dynamat is a wonderful heat buffer. I drive my cars in Louisiana and Florida, and the only heat I feel is the sun and humidity! I feel no heat from the engine, transmission or exhaust. It is the way it should have been all along! I do not recommend purchasing Dynamat from any of our common LBC parts suppliers. You can get it cheaper if you buy the big box of it at a car stereo place. The last time I bought it, the salesman used to own a Healey, so he gave me a 15% discount, since I promised to bring the completed car by the shop!
 
Has anyone had any experience with this product?
https://www.koolmat.com/main.htm
I was turned on to it by a street rodder who said it out performed the Dynamat. And from what BlackHealey says about the Dynamat performing well, I'm encouraged. I've covered my car's floor, tranny tunnel and firewall but I'm still waiting on my motor so I don't really know how well it works.
 
I don't know, but they are showing an example in a Healey on this page

https://www.koolmat.com/british.shtml

It says that Tsikuris Classics is offering pre cut kits. They have the phone number, but no email address.

I think Paul Tsikuris did work on Randy Forbes's BN6. Randy, if you read this, do you have an email so we can ask how much.

If the Jag price is any indication, its would cost more than I just payed for my Moss Carpet!!!
Patton
 
Randy, where are you?
RANDY? RANDY!
Well, I can tell you it was expensive. I bought it by the foot and cut it to fit myself.
I'd love to know, first hand, (or second)if it works well.
