The invention relates to construction, in particular to a special tile, which provides thermal and heat insulation, not harmful to the environment, accumulates solar energy and generates electrical energy, and which can be used in the construction of roof coverings for roofs of industrial and public buildings and structures. A roof tile comprises an upper protective layer, under which a photovoltaic cell is mounted, wherein the upper protective layer is formed from polyethylene terephthalate, and the following are arranged consecutively under the photovoltaic cell: a heat-insulating and sound-insulating layer made from polyurethane foam, a cardboard layer, a technical layer formed from high-pressure polyethylene and a lower protective layer formed from polyethylene terephthalate with a metallized base. The metallized base is formed from aluminium. The upper protective layer is made transparent to allow solar energy to pass to the photovoltaic cell.

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.

A method of manufacturing a conductive roofing board may include pouring a polyisocyanurate foam on top of a facer. The method may include laminating the polyisocyanurate foam and the facer to cure the polyisocyanurate foam and adhere the polyisocyanurate foam to the facer to form a roofing board. The method may include applying a conductive coating to an exposed surface of the facer, wherein the conductive coating has a coating weight of between about 0.1 lb/100 sqft and 10 lb/100 sqft. The method may include exposing the roofing board and the conductive coating to a heating device to cure the conductive coating.

A formaldehyde-free binder composition for mineral fibers which comprises at least one phenol containing compound and at least one protein.

An aqueous binder composition for mineral fibers which comprises at least one polyelectrolytic hydrocolloid.

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.
