Insulated roof construction
First Claim
1. A thermal insulated roof construction comprisinga. a roof support means,b. a water-impermeable layer overlying said roof support means,c. a layer of thermal insulation overlying said water-impermeable layer and being unattached thereto throughout essentially its entire extent, said layer of thermal insulation being comprised of a plurality of panels position in side-by-side abutting relationship and having upper and bottom faces grooves and ridges being formed in the upper faces facilitating water drainage from the ridges into the grooves, said panels being formed of a closed-cell cellular material and being essentially water-impermeable, andd. a water-permeable protective layer overlying in contacting relationship said layer of thermal insulation to shield said layer of thermal insulation from sunlight.

Abstract
A built-up insulated roof construction is provided that includes panels of closed-cell thermal insulation foam disposed over a water-impermeable barrier layer. A protective layer is applied over the panels of thermal insulation foam. The upper face of the insulation panels contains grooves or channels to aid in the evaporation of moisture through the insulation panels to the outside atmosphere.
