A panel useful as a roof deck material (and optional insulating material, and optional moisture barrier) for a roof of a building or as a wall material for a wall of a building comprises a plurality of side members comprising at least a first side member, a second side member, and a third side member. A void capable of receiving an insulating material exists between at least the first side member, the second side member, and the third side member. The panel also comprises a plurality of stiffeners comprising at least a first stiffener spanning a first distance between at least two side members of the plurality of side members.

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.

A method and system for adhering roofing products to a supporting roof substrate, wherein ballast rock from a pre-existing roof insulation system is removed thereby exposing one or more layers of pre-existing insulation products supported by the roof substrate. In the case of new construction, the method contemplates installation of one or more layers of insulation products supported by the roof substrate. Core holes are formed through the one or more layers of insulation products thereby exposing the roof substrate. An anchor is attached to the roof substrate in each core hole void, and a binding agent is applied to each core hole void until the binding agent fills the core hole void, whereby the one or more layers of insulation products and roof substrate are locked together, preventing shifting of the insulation products without the need for adding ballast rocks thereon

The present invention relates to a cladding or covering sheet for roofs or walls including a plurality of first fold lines or ribs spaced apart from each other and a plurality of second fold lines or ribs spaced apart.

A roofing system including a plurality of roofing panels that can be releasably secured to rafters or other supports of the roof by connectors. In embodiments, the connectors can include first and second connectors, each of which can include a plate with a projection extending therefrom, and with the plates defining flanges on each side of the projection. The plates of the first and second connectors are configured to seat on and at least partially extend along one of the rafters of the roof structure and along exterior facing surfaces of adjacent ones of the roofing panels to releasibly secure the roofing panels to the rafters.

A metal roofing system contains, in order a roof deck, a fire resistant (FR) fleece, and a metal sheeting system. The second side of the FR fleece faces the roof deck. The FR fleece contains a plurality of FR staple fibers and a plurality of first char scaffold fibers. The FR fleece has a fleece thickness defined as the distance between the first side and the second side. The metal sheeting system contains a plurality of metal sheets having an upper and lower side, where the lower side of the metal sheeting system faces the first side of the FR fleece. The metal sheets have an average metal sheet thickness defined as the distance between the upper and lower sides, where the thickness of the FR fleece is at least about 3 times the average metal sheet thickness. The FR fleece has a density of less 0.5 g/cm.sup.3.

A hook and loop system for attaching a roofing membrane into the top of a building insulation board including a roofing membrane with a fleece backing having a release sheet on the fleece backing. The release sheet is manually removed in the field to attach the fleece backing directly onto a layer of hooks that have been pre-attached onto the top of the insulation board. The release layer may be somewhat sticky, yet not adhere too tightly to the fleece layer such that its removal does not damage the fleece backing. The release layer may also be pre-rolled together with the fleece backed roofing membrane and shipped together as a unit into the field.

The present invention provides a multi-layer roof system, and an installation method. The multi-layer roof system comprises a roof truss; and a multi-layer panel comprising a base layer, a plurality of intermediate layers, and at least one coating layer placed over the plurality of intermediate layers. The base layer comprises at least one membrane of waterproof or water resistant material configured to provide an under-laminate capable of being affixed to a building structure with no screws. The plurality of intermediate layers comprises a first intermediate layer, a second intermediate layer and a third intermediate layer. The first intermediate layer comprises a cooling layer. The second intermediate layer comprises a mesh layer. The third intermediate layer comprises a reflecting layer. The at least one coating layer may comprise a plurality of coating layers. The multi-layer roof system provides a multi-layer building roof structure configured to be both structurally sound and energy efficient.
