A modular composite panel comprised of a solar photovoltaic panel, a solar thermal collector panel, and an engineered torsion box containing a layer of insulation. Multiple composite panels can form a roof when installed in an array, with panels abutting and situated side-by-side on a structural frame or other suitable support system. A composite panel may span between structural members without requiring intermediate support. A composite panel array can provide weather protection, electricity, and hot water to an enclosed or unenclosed space below. Together with insulated walls, the array of composite panels can provide thermal insulation to an enclosed space below.

A sandwich panel including a first planar structural outer layer; a second planar structural outer layer orientated substantially parallel to the first planar structural outer layer; a core layer sandwiched between the first planar structural outer layer and the second planar structural outer layer; and a plurality of openings extending through the core layer in a longitudinal direction substantially parallel to the plane of the first and second planar structural outer layers, wherein the plurality of openings are surrounded on all lateral sides by the core layer.

A self supporting panel system used to fabricate ceilings, floors, walls, or roofs. The panel system is assembled from a plurality of panels, each having a core that is sandwiched between opposing plate members. In a preferred embodiment, the core of each panel includes a unifying material to enhance the load bearing capacity of the panel.

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.

In a method of repairing a blistered portion of a thermosoftening membrane, a heated air dispensing device is provided, having an elongated nozzle including at least one outlet aperture. The blistered portion of the thermosoftening membrane is pierced to form an opening sized to receive the elongated nozzle. The elongated nozzle is inserted through the opening and into an interior cavity of the blistered portion, with the interior cavity being at least partially defined by a thermosoftening material. The heated air dispensing device is operated to dispense heated air through the at least one outlet aperture into the interior cavity of the blistered portion to at least partially melt the thermosoftening material. A force is applied to an exterior surface of the blistered portion to flatten the blistered portion, thereby substantially eliminating the interior cavity.

The subject of the present application is an arrangement of sandwich panels already used in buildings in a way that makes them capable of collecting solar radiation and ambient heat and transferring the energy out of the roof. The structural elements of the present invention consist of a heat insulating core sandwiched between external and internal sheets with load-bearing capacity, similar to the make-up of the known load-bearing sandwich panels. Whether the sheet profiles are placed in the direction of the ridge beam or of the rafters, with the appropriate set of them, hollow structure is created on the surface and in the core of the panel in the direction of the rafters, in the entire length of the roof, functioning as pathways for gaseous materials (air ducts (1, 4)). If these air ducts, both external and in the core, are connected at the end facing each other, i.e. at the upper air turn chamber (8), the substance in them will start to flow on its own using solely gravitational forces in reaction to heat reaching the panel's external surface, i.e. the external profiled metal sheet (2). If a given point of the panel is cooled by heat exchanger (6), the spontaneous flow will remain continuous. Cooling transports the heat collected in the air ducts (hot air duct (1) and cold air duct (4)) out of the system, and this heat is utilized to provide for our energy needs. The subject of the application is, therefore a sandwich panel which functions as a thermal collector, hereinafter heat collector sandwich panel (3), which serves as the roof structure of a building, or is an integral part of the roof structure and meets without fail all protection requirements set for roof constructions. Due to its special design it is capable of collecting ambient heat, and transferring this heat to heat storage by the use of compatible, known auxiliary appliances.

The invention relates to a roof forming element for a roof, comprising a roof plate, a beam integral with the roof plate, such that the integral combination of the roof plate and the beam has an L-shaped cross-section, a cover, and coupling means for coupling the roof forming element to a further, neighbouring element. The roof forming element, at least in a mounted condition of a plurality of such elements, is configured such that the second longitudinal side of the element is arranged to be supported by the first longitudinal side of a further, neighbouring one of said elements, so that the beam of the further roof forming element also supports the roof plate of the roof forming element, and so that the respective roof plate elements of said roof forming element and further roof forming element are flush with respect to each other.

A multi-functional tray that can be used in various applications to form different products, such as planter board for green roof plantation, thermal insulation structure for roof deck insulation, solid concrete panel for building construction, etc. The tray comprises an upper portion, a lower portion, and a backing layer connected between the upper portion and the lower portion. The lower portion comprises a plurality of reservoirs with through holes. The upper portion has a plurality of partitions and securing units to secure the material in the upper portion.

Solar PV devices are disclosed, wherein these devices are produced as an integral part of a structural panel. The structural panel may subsequently be used in any number of ways, including being made an integral part of a building structure such as a wall or a roof or another type of barrier structure, or simply a stand-alone array or even a retrofit addition to an existing structure. In embodiments, the panel comprises a semi-monocoque structure, which can provide strength and stiffness. The core of this semi-monocoque can provide an enclosure that functions to confine the solar PV's electrical system within an electrically insulating structure that provides dual insulation and may enables a dual-insulated rating. Embodiments of the panels disclosed herein also can provide cooling air flow to provide cooling to the panel.
