Disclosed herein is a method of manufacturing an improved cover board product with a panel. In some embodiments, the method includes preparing fragments into an assembly; mixing the fragments and an adhesive into a blended core furnish; applying the adhesive to a top side of a bottom layer fabric in the assembly; forming a core mat of the blended core furnish on top of the adhesive; applying the adhesive to a top side of the core mat; applying a surface layer fabric on the top side of the adhesive; pressing the assembly; and cutting and trimming the assembly to form panels.

Support members for a roof system are provided to allow for positioning panels of a roof apart from building members so that building components, such as insulation may be placed between the roof panels and the building members. The support members may be utilized in new buildings or to retrofit existing buildings. Each of the support members may comprise a single support member that has a base portion operatively coupled to an offset portion that is operatively coupled to an upper portion. One or more channels may be provided in the base portion, offset portion, and/or the upper portion to provide structural support and to allow the support members to be operatively coupled to each other and other building members without the need for additional components.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

Composite roofing structures can include mineral fiber roof cover boards with high concentration of mineral wool or mineral wool and perlite. The roofing structure may include: a roof cover board including a dried base mat including: 8-25% mineral wool, 40-65% perlite, 9-15% binder, 9-15% cellulosic fiber, and 0.25-2% sizing agent, all % by weight; an insulation layer; and a roofing membrane. The roof cover board is over the insulation layer, the roofing membrane is over the roof cover board. The roof cover board is attached to the insulation layer. The roofing membrane is attached to the roof cover board. Alternatively dried base mat may include: 30-70% mineral wool, 10-50% perlite, 5-15% binder, 2-20% cellulosic fiber, and 0.25-2% sizing agent. Alternatively the dried base mat may include: 60-90% mineral wool, 0-10% fiber, 0-10% perlite, 4-10% binder, 0-5% gypsum, and 0.25-2% sizing agent.

An improved cover board product with a panel comprised of three discrete layers: a top surface layer comprised of either paper or a fiberglass web, a bottom surface layer comprised of either paper or a fiberglass web, and a core layer comprised of discrete paper fragments and polypropylene fragments, which are connected by use of a thermoplastic bonding resin, including polyethylene. The bonding resin is generally attached in a random pattern to less than 100% of the paper fragment and polypropylene fragment surface area. The paper fragments are generally shaped as irregular plates. The polypropylene fragments can have multiple shape types. The two different fragment types are randomly distributed in the core layer relative to each other. The core layer includes small voids in and around the particles, which improves flexibility. The core layer is attached to the top and bottom surface layers by use of a thermoplastic adhesive, including polyethylene.

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.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.
