Use Dynomat Extreme?

I am at the point where I need to do my entire interior with Dynomat or something similar. Primary focus is heat though I have a rocking sound system and it will help in that aspect as well. I need recommendations on what to use and how much it takes to do a C3 interior. Any help is much appreciated.

Dynomat is a sound deadener. If insulation is your main concern look at the AC/heating dept at the hardware store (HomeDepot/Lowes). Reflectics is cheap and does a good job on thermal insulation. It's doubled aluminum foil with bubble wrap in between... air is a terrible temperature conductor.....it's in the water heater section...

How about for my doors,i have been thinking that before i put the door panels back on that i should insulate,mainly for noise. I have the plastic that came from the factory still,but it does not do much.

Thank you very much, that is WAY cheaper then the dynomat extreme. I assume this stuff is not peel and stick, whats the preferred method of installation?

It's not nearly as durable either, dynomat, fat mat and all those are similar. Bitumen base with reflective foil on top. I would use that.

I agree it might not be as durable but under the carpet it should be fine - I used this stuff under my carpet and it's there for over two years now... I'll have to see if it's torn or shredded :confused2:

Reflectix is not peel and stick, I used 3M spray adhesive. Once the carpet is installed it won't move even if the glue fails....

Is Dynamat any good for insulation ? I think it's only a sound deadener, not ??

i use lizardskin in all my builds. it stops heat migration which dynamat will not nor will reflectic . i use the sound control and heat control from lizardskin . with these products you dont have to use thick carpet pad. even running flowmasters you can still talk when driving. you can see in this pic that the carpet fits well with just 1/4 in rubber backing . plus it is not glued down and can be removed if need be. this truck was really quite and a/c worked great even in aug here in texas.

Not familiar with the auto specific stuff, but some of it sure sounds like an aluminized Peel and Stick roofing material. Might just be the same stuff repackaged at a higher price.

It supposedly at peak times can reduce attic temps by as much as 80°. The secret to that would be that it would have to be installed on the heat side or outside the cabin and not inside.
Simple foil does have a decent "r" value because of it's reflective properties in building situations and is available in that form too.

Just food for thought.

Yeah I'm pretty sure it's the same stuff, I felt dynamat at the store and couldn't tell the difference

My dad uses that peel and stick

Damnit man, just Damnit....wish I knew of that stuff some years ago when building my room addition, that rolled ass fault roofing I got on my plywood roof, and trying to cover a aluminum addition we framed in for my neighbor buddy next door, we have our troubles....but peeling all that shit off there, and using that stuff on the naked plywood sounds just like the ticket....

some 6" left over white aluminum taping was used on a aluminum addition across the street some years ago, and it's on my rood now, fixing anything possible in skylight leaks, works like a charm...as good now as when I put it down some 3 years ago....also looking at covering the glass roof of the atrium on account of it's just tooooo dam hot in that thing in summer....

Great link Noonie, thanks....

:bounce:

I put that rubber paint "All White" over top of bare plywood for a patio addition roof. Covered the seams with a thin narrow fabric and painted that in for expansion. No leaks and better than tintagged normal roof for hurricanes too.
You can also use some thin fiberglass mat (1.60/yd) and paint that in the whole roof, but it will take a lot more paint.
Cheaper than the peel and stick.

On the glass atrium the peel and stick is probably best.

Don't let the code cops catch ya. :yahoo:

Yes it is the same, same for fat mat, rattle trap or whatever you have out there. I always use the polyguard type stuff.

Applied over a shed roof on a 300' room addition with mild pitch...maybe 1-12 and being plywood, why you say about code cops....I"m not on the beach, way inland 45 miles, and on a hill side....

honestly, I was thinking of it for the entire backside of the house, in white and not showing from the street....that white should drop 500F outta that attic, I would think....course I cant help the front, as the house faces directly west....then again the guy facing south just up hill and around the corner put on some hideous blue metal roof and spend tons of bux to do it....

With the carpet and jute padding, be careful not to get something too thick. I think that 1/8in is about the max....but I haven't done mine yet.

The roof stuff is a little thinner than an 1/8th not much though

The Dynomat Extreme is supposed to reduce heat, though I cant see any actual refrence to its r value. It is really expensive too.

Marketing... A lot of hot rod TV builders (Foose, Trepanier, ect) use it for mega $$$ cars so Dynamat will be expensive.

Found a knock off called Voodoo its 36 square feet, peel and stick. It is slightly thicker then the Dynamat Extreme for $84 plus $13 for shipping with a free roller included. Does anyone know if 36 feet will do the whole car? (81)

I don't reckon it would be - that's only 6ft x 6ft. It would probably come close but if I was buying it, I'd buy more whereas you could easily go back to the shop and buy more if you needed it...

I used 2 rolls to do an coronet station wagon, 1 roll would do the floor panels and maybe the storage bin floor. the trick is to use a heat gun to get it hot, it'll form to most surfaces really easy and stick like mad
