Q: How is this Koolmat Insulation attached? Does it have an adhesive back or does it require some special glue?

This material is not adhesive backed. It does not have a special adhesive for attaching it but a common adhesive used is our part number 05-00949.

Q: What color is the front of the Koolmat Insulation Heat Barrier? Does it come in other colors?

The color in the front would be gray. This can be special ordered in beige but the minimum purchase qty would be 150ft.

Q: Assuming this Koolmat insulation material will not absorb oil (as in use in the bottom cowling), how will it fit curved surfaces-is it stretchable?

It will not stretch well around complex curves or shapes.

Q: Is this to be used in front of the firewall (between firewall and engine) or on the cabin side of the firewall?

Most customers use the Koolmat material on the firewall engine side with the gray side facing the engine because it won't absorb any liquids. It can be used on the inside to keep heat out of the cockpit area also.

Q: Is this Koolmat insulation FAA approved?

No, there is no FAA Approval tied to this product.

Q: Can this product be sewn as a layer in a firewall blanket? I read it is effective with heat. How about noise?

The material is flexible, so if you can sew thru the silicone and fiberglass, it should work for you. We do not have any documents of its soundproofing capabilities, so we can not say how much sound damping it would provide.
