An insulated panel assembly having improved insulative R-value. The insulated panel assembly comprises a cover panel, a first insulation layer, and at least one additional insulation layer, wherein the at least one additional insulation layer has a higher R-value than the first insulation layer. The first insulation layer is secured to the cover panel. The first insulation layer further forms at least one recessed portion. The at least one additional insulation layer is positioned in the at least one recessed portion of the first insulation layer. Examples of the at least one additional insulation layer may include vacuum insulated panels and modified atmosphere insulation panels.

This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).

A non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.

A plurality of ventilation elements, vents, slots, or gap elements or similar features that are applied to, or machined into, one or more sides or faces of exterior siding products. When the exterior siding product is installed, the ventilation elements, vents, slots, or gap elements or similar features provide a built-in air and water gap to facilitate and increase water drainage and air circulation behind the siding or panel, thereby minimizing water storage in the space behind the product and lowering the equilibrium moisture content of the siding itself. The ventilation features are incorporated into the corresponding product in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site (e.g., furring strips or other similar drainage mechanisms are not needed).

A siding material for a building configured to hold one or more solar panels is disclosed including a siding shell including a first section and/or a second section, wherein each first and/or second section includes an essentially flat face disposed at an angle ranging from about 30 degrees to about 90 degrees relative to the ground or a perpendicular plane extending from a side of the building. In addition, one or more surfaces of the first section and/or the second section are perforated, and the first section and/or the second section each include a channel configured to hold an electrical cable.

A panel configured for attachment to a mounting surface includes a plurality of raised faces that are formed between an upper edge and a lower edge of the panel. A shoulder is defined on the raised faces adjacent the upper edge and is spaced from the mounting surface, when assembled or attached thereto, by a shoulder offset. A plurality of keyways are recessed between each of the raised faces and are spaced from the mounting surface by a bottom keyway offset adjacent to the butt edge. The bottom keyway offset is substantially aligned with the shoulder offset.

A ceiling panel according to the present invention has opposed translucent membranes secured in a tensioned state across a perimeter frame. The frame includes frame members that are designed to oppose inward bowing of the perimeter frame caused by the tensioned membranes. The frame members have a side profile shaped to conceal a grid support network with the lower translucent member extending across and about a lower edge of the perimeter frame. The invention also includes a modified structure for supporting of translucent panels below a grid network.

A building siding panel is provided with an internal channel for weeping away water and the ability to hide the securing flange when the siding panel is installed on a building wall. The siding panel can be customized to have the look of a wooden panel, while retaining the benefits and durability of a non-wooden material, such as metal.

An insulated building structure, in particular an insulated roof structure or a wall structure of a building, comprises at least one thermal insulation layer. At least one moisture-variable protective layer for the thermal insulation layer is provided on an outer side of the thermal insulation layer and on an inner side of the thermal insulation layer facing a building interior of the building. The protective layers each have a water vapor diffusion equivalent air layer thickness S.sub.d. The water vapor diffusion equivalent air layer thicknesses S.sub.d of the two protective layers deviate from each other by less than 20%, preferably less than 10%, in the range of a relative humidity from 0% to 25% and/or in the range of a relative humidity from 80% to 100%.

An insulating siding panel comprises a backing member, and a siding member. The backing member comprises a front face, a rear face, a top face, and a bottom face. The siding member has an upper end, a lower end, and a nailing divot. An upper end of the backing member combines with the upper end of the siding member to form a tongue. A groove is defined in the bottom face of the backing member that is complementary in shape to the tongue. the nailing divot of the lower panel may be concealed by a front section of the backing member of the upper panel.
