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.

The insulating barrier of a panel including has a first stratum and a second stratum, each having a plurality of ridges that face each other, and run athwart of each other. Clearance between at least some adjacent pairs of the ridges provide a mechanical chase that reaches across at least most of the panel. A cladding overlaying at least one side of the insulating barrier is denser than the barrier. The mechanical chase is in the form of a groove through which a utility feed can be routed when the panel is to be mounted in a building.

A roofing board, such as a polyiso insulation board, includes first and second surfaces, where the first surface is lighter in color than the second surface. This allows the roofing installer to choose which of the surfaces to expose to the atmosphere, the lighter surface being cooler than the darker surface. The lighter surface may have a solar reflectance greater than the darker surface. A roofing membrane is then adhered or otherwise attached to the exposed surface.

The disclosure relates to a thermal and/or acoustic insulation system as waterproofing for a flat or flat inclined outside surface of a building, especially for a flat roof or a flat inclined roof, consisting of at least one insulation element made of mineral wool, preferably made of stone wool, and having a major surface, and a lining element consisting of at least a first layer made of lining material and a second layer made of a glue activatable by heat and oriented to the major surface of the insulation element, whereby the major surface of the insulation element is free of protrusions, especially flights, and cavities thereby being planar and whereby the area connection between the insulation element and the lining element is at least 70%, preferably at least 80% of the major surface area of the insulation element.

A panelized building system and method of construction utilizing a rigid framing combined with foam insulation is disclosed. The system may include a metal roof panel, at least one metal wall panel, a floor panel, at least one metal corner post and at least one foundational component. A single layer of foam insulation encapsulates partially fills a rigid framing and may be molded against a non-stick surface or bonded to an exterior building material. In either case, a single monolithic piece is formed. A utility cavity may be formed interior to the single layer of foam insulation. The exterior face may be textured, undulated, radiused, or shaped in myriad ways.

One subject of the present invention is a roofing device (1) comprising an area support (2) made up of panels of wood particles on which a vapor barrier first layer (3), an insulating second layer (4) and a third layer (5) that is impermeable to liquid water are laid. Said device (1) is one wherein the second layer (4) is a composite layer formed by the superposition of two distinct homogeneous elementary layers (6 and 6), namely a lower elementary layer (6) of wood fiber and an upper elementary layer (6) made up of a material that is at least partially bio-sourced, that has hygroscopic, antifungal and thermal-insulation properties and that has a low resistance to the diffusion of water vapor.
