Abstract
Abstract A laminated roof construction and a method of forming the same wherein the roof comprises a supporting deck having a water-proof intermediate membrane upon which is superimposed a heat resistant sandwich-type foam panel. The foam panel consists of a cellular foam-like material such as polyurethane and similar substances, and this foam material has a top and bottom skin or film adhered to the foam. At least the top skin is weatherproof and is resistant to actinic rays.

Claim 12
Independent Claim
58 words
A method of making an insulated laminated roof which comprises positioning a roof deck in place, adhering a water-impermeable membrane in superimposed position on said roof deck, and adhering a heat and actinic ray-resistant panel in superimposed position on said membrane, said panel being of foam interior construction and having adherent skins on its upper and lower surfaces.
Claim 13
Dependent Claim
30 words
The method of claim 13 wherein said membrane is formed by applying an elastomeric precursor to the upper surface of the roof deck, and then polymerizing said precursor in situ.
Claim 14
Dependent Claim
34 words
