I have heard a lot of good things regarding Dynamat and Dynaliner. Is it necessary to use Dynamat under Dynaliner if I am more concerned about reducing the heat in the driving area. The site recommends using the Dynaliner on top of Dynamat.

Has anyone just used the Dynaliner? Any suggestions??

Thanks

I think Dynamat and Dynaliner are acoustic barriers and not designed to be a thermal barrior. A better thermal barrier would be foil/foam/foil or foil/bubble/foil/bubble/foil.

To reduce the heat soak of the firewall and floorpan a foil covered insulation could be applied to the engine side.

Dyna Shield is nice for small areas. I tried Extremeliner, yet more Dynamat product (try spreadable Dyna-Cheese as a tasty snack with crackers.) on the inside firewall area, but not sure if I would bother doing that again. It's rather bulky (4 part composite with lead barrier!), heavy and expensive. I think the DynamatExtreme provides some basic thermal resistance that's enough for I need it for.

Yes, anything is a lot better than nothing. I've used insolite camping pads under the carpet because that's what was in the garage! They are light and insulate well.

I used a 1/4" wool type insulator backed with foil on one side. Easy to cut and fit. Basically its a water heater type wrap. About $35.00 was enought to do the entire interior and part of the trunk. Can't remember the name of it but I bought it from

Give them a call to find the mfg name, do a web search for their site and find a local dealer to see first hand if you think it might be ok for you. I am pleased with the results so far. I used spray adhesive to get it to stay put in vertical and other difficult areas and foil tape to seal seams where necessary.

Never drove the car prior to installing so have nothing to compare to but its gotta help.

Thanks to all for your help.

Kurt, have you tried the material from the "insulation4less" site? In particular the Prodex which is the foil-foam-foil material. It looks promising.

DynaCheese!!!! - I smell a rat.

Though not specifically designed to heat insulation, Dynamat and it's clones do an exceptional job of insulating heat, within limits.  I remember seeing stats that siad it was good to 250 degres F.

I now have a MiniTemp and will try to get some actual field results.  Will post here, but I am sure that you will be impressed with the sound insulation alone.  I swear by the stuff!
