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.

Abstract: A flashing system for weatherproofing the areas between adjoining structural surfaces which are continually exposed to ambient conditions. A longitudinally extending bracket member is adapted to be secured to a structural surface such as a building parapet or the like. The bracket includes a longitudinally extending opening. A sheet of flexible material (preferably elastomeric) material is supported by the bracket member and covers selected areas between the adjoining surfaces. The sheet of flexible material extends through the opening in the bracket, and a stiffening member in the form of a longitudinally extending planar member has a portion secured to the sheet of flexible material. Part of the bracket member defines a longitudinally extending track portion designed to slidably engage a longitudinal edge of the stiffening member.
