firewall insulation

Too much heat coming through my 48's floor/firewall. I don't know what would be an effective cost affordable material, reasonably easy to manipulate
Found Hp sticky shield on internet but is a bit pricey.
Bob Drake offers insulation sheeting. Anyone know how effective BD's is?
Any other effective, heat reflective choices out there?
Thanks
This is my first post. Where would I, duh, look for a reply?

when ever i insulate a vehicle i do, either for sound deadening or heat ive found a cheap and easy fix is the stuff used for roofing...peel and stick i think its called. any menards or lowes or home improvement store should have it. It may or may not be what your lookin for, but its worth lookin into. Hope this helps.

sounds in my price bracket and worth a try if I can find it. Peel and stick roofing is not something I am familiar with.
Is it asphault based?
Thanks

Apparantly this material is difficult to locate re; other forums and may no longer be available.
Home Depot has picked up the slack with "quick roof" which appears to be the same thing but not available in Canada
Anyone aware of a similar Canadian product
Thanks

I sprayed Lizard Skin in my 32 3W. Then I used Dyna-Mat ... my coupe has Vintage Air and you can hang meat in there with the A/C going



Before Lizard Skin on the door.





With Lizard Skin sprayed on the door.


I did the entire coupe. The floor, roof, doors and the trunk. The coupe is quiet inside and well insulated. Not cheap ... but well worth the $$$ in my opinion.

Interestingly, I just came across Lizard skin in another forum.
I will see if I can track it down.
Lots of different solutions. I should be able to stop frying my toes!

Another product worth looking at is called Spectrum Firewall by Second Skin Audio. I used this on top of their Damplifier pro in my 53 Ford truck. Not cheap but you get what you pay for sometimes....worth the $$ if you want a comfortable ride. The Firewall coating can be brushed on if you are concerned about overspray. Regards.

Just chased that down on internet. Would you say it significantly decreases heat transfer through floorboards/firewall or would it's contribution lean toward sound suppression.
This is likely another product difficult to obtain in British Columbia.
Thanks for the info. Haven't done anything yet as I will have to strip out significant amount of interior which will have to wait for winter weather to happen!

I would say both. It also depends on how thick you lay it on....how many layers/other products above and below it etc. I didnt realize you were in BC but if I had to choose one product I would say Dynamat or Damplifier Pro.....or something along those lines if you can get it. Use the butyl rubber stuff and not the asphalt impregnated ones.
They will give you both heat and sound suppression. The Damplifier Pro does both as it has a fairly thick foil shield on it....it cost me about 8 bucks a sheet. And you can always lay down a layer of the less expensive foil faced padding over it for a little extra....I think I paid about $30 for a roll of that. Regards.

Here's what I used:
E/O 12 in. x 15 ft. Self-Stick Foam/Foil Duct Insulation-FV516 at The Home Depot

Self adhesive, dense gray foam, and foil backed. It cost me about $30 for the whole interior on my car. Two 15' rolls, and really reduced the heat transfer on the firewall.
