Hi



Wandering through the things I book marked over the past few months; I came

across a product called Koolmat. I must have kept the link as I was

interested in something I could use to insulate the floor pan area - I am

primarily interested in safety in case there is an engine fire. 



Not having used this product, would anyone who has used it let me know if it

water absorbent. I don't want to put anything in the foot well that will

absorb water. 



On a related note, what would be the best adhesive to use to hold it down? I

want to avoid using any adhesives that can support a flame. Is there a

general purpose adhesive that could be used in this and similar applications

that are non flammable?



Inquiring minds need to know ....

Les,

I have Koolmat on my firewall. It is a fberglass mat with a impregnated silicone covering, about an 1/8" thick total. I don't think the glass side could absorb much water, definetly not the silicone side. I used red RTV to attache on small dabs. It's pretty tough stuff. I super sound proof insulation in the floor pan areas and cut it for a friction fit, no adhesive except a small dab of silicone if it showed any lifting.

I also used the super sound proofing under the floor pans.   Under the front 

floor pans I used the 1" thick version and just did a tight fit,  no 

adhesive.   Under the rear seat floor pans I used 3/4",  its a perfect fit. 

I also used the 3/4" thick under the rear seats and under the baggage 

compartment floor.    In these two areas I used the adhesive backed version 

of the insulation as there is nothing really holding the insulation down. 

On the firewall I'm also using the Koolmat material.   I've been scratching 

my head on how to fasten this stuff down.    The RTV idea seams reasonable. 

Also I was curious as to how flame retardent the super sound proofing was, 

so I took some pieces outside and tried to set them on fire with a propane 

torch.    The stuff just kinda curled up and melted, but definetly did not 

support any flame at all.   It did stink the high heaven and you'd definely 

need some ventalation if you melted this stuff inside the cabin, but it 

certainly did not catch fire.



Also this Koolmat seems to be the only stuff I've seen intended to be put on 

the engine side of the firewall.   I think this makes great sense, as 

keeping the heat from passing thru the firewall in the first place is the 

best way to keep the cabin cool.

Question? Is this material fuel resistant? Question? What"s to become of the fuel you spill when you change your fuel filter? I know its not a lot but.....

  Thanks

  Just wondering
