A roof deck (20) has plurality of insulated panels (22) secured together by a first plurality of fasteners (54) along their longitudinal edges (28, 29). Additionally, the panels (22) are secured by a second plurality of fasteners (56), transverse to the longitudinal axis (26), to a framework (18). A plurality of washers (60) disperse the force of the second plurality of fasteners (56). The plurality of washers (60) are secured to each of the second plurality of fasteners (56). A membrane (24) covers the roof deck (20).

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.

Interlocking laminated structural roofing panels have a lightweight foamed core sandwiched between outer and inner layers of materials such as wood, polymer materials, fire resistant and/or waterproof membranes, and metal layers. At least one layer is a self-gripping metal sheet that grips and bonds mechanically to adjacent layers such as wood layers. A self-gripping metal sheet may be used on both sides of the roofing panels to form a panel that is strong, structurally robust, and able to span between relatively widely spaced roof rafters with little or no mid-span support. Interlocking features along the edges of the panels interlock adjacent panels together to form a strong monolithic roof covering for a roof.

In a roofing structure, two roof panels with different slopes and lengths are positioned back-to-back, the vertical back walls of the panels having a uniform height. The seam between the two differently-sloped panels are connected by a ridge cap set at a uniform height. The ridge cap covers the seam, extending on both sides to a distance from the back walls of the roof panels sufficient to create a capillary break therefrom (preventing moisture migration) and then downwards and slightly towards the back walls of the roof panels, thereby using gravity to direct the water into the downward sloping roof panels.

A method of constructing a roof assembly, the method comprising (i) mechanically affixing a construction board to a roof deck; (ii) providing a composite insulation board including (a) at least one vacuum-insulated capsule; (b) a foam body that encases said at least one vacuum-insulated capsule, said foam body having first and second opposed planar surfaces; (c) a layer of pressure-sensitive adhesive disposed, either directly or indirectly, on one of said first and second opposed planar surfaces; and (d) a release liner removably attached to the layer of pressure-sensitive adhesive; (iii) removing the release liner from the composite insulation board; (iv) mating the composite insulation board to the construction board that is mechanically affixed to the roof deck; and (v) installing a membrane system over the composite insulation board.

A covering system provides a structural insulated panel for covering a roof having standing seams. The insulation is a composite core made of EPS and other polymers such as polyurethane. At least one panel covers a mounting surface, like a roof, and at least one protruding seam on the roof. The panel utilize a deformation, or crimping to form connections with adjacent panels and attachments with the mounting surface. A bracket fastens to the mounting surface by crimping onto the protruding seam. An exterior portion includes a pair of stabilizers that extend outwardly. A pair of stabilizer ends crimp onto a support portion of the mounting bracket for fastening. The crimping mechanism minimizes the need for penetrating the mounting surface with fasteners and reduces space between seams.

The present invention relates to a method of producing a coherent growth substrate product formed of man-made vitreous fibres (MMVF), comprising the steps of (vi) providing MMVF; (vii) providing an uncured binder composition; (viii) providing a superabsorbent polymer; (ix) forming a mixture of the MMVF, the uncured binder composition and the superabsorbent polymer; (x) curing the uncured binder composition in the mixture to form the coherent growth substrate product; wherein the uncured binder composition comprises at least one hydrocolloid.

A construction board includes a foam body having first and second planar surfaces, said foam body including a polyisocyanurate foam matrix defining a plurality of closed cells, said closed cells being at least substantially devoid of hydrocarbon blowing agents, and said foam body being characterized by a density, pursuant to ASTM C303, of at least 2.5 lbs/ft.sup.3; and a facer disposed on a planar surface of said foam body, said facer including a glass substrate having an internal planar surface proximate to said foam body and an external planar surface opposite said foam body, a first coating disposed on said external surface, and a second coating disposed on or proximate to said internal surface, where said first coating disposed on said external surface includes an inert filler, and where said second coating disposed on or proximate to said internal surface includes intumescent material.
