An insulation panel is described that is adapted to be installed between framing members of a building, such as a stud, joist, or rafter. The insulation panel can be installed without the use of fasteners or adhesive. The panel is made of a rigid insulation material such as expanded polystyrene. Grooves are provided along a length of the panel to allow for compression and accommodation of variations in the spacing between framing members.

A heat collector device is provided. The heat collector includes an exterior surface exposed to an environment, and an interior surface. Side walls separate the exterior and interior surfaces. A heat insulation interposes the exterior and interior surfaces. Each hot air duct includes a first portion interfacing with the external surface and a second portion interfacing with the heat insulation. Each cold air duct is encompassed by the heat insulation. A first chamber formed by a first side wall provides fluidic communication between the air ducts at a first end portion of each respective duct. A second chamber formed by a second side wall provides fluidic communication between the air ducts at a second end portion of each respective duct. A heat exchange mechanism disposed in the second chamber removes heat from a first fluidic medium of the air ducts, the first chamber, and the second chamber.

The present disclosure relates to a prefabricated module for a pitched roof element comprising a frame made of at least two first beams being arranged in a distance and running parallel to each other and two second beams running rectangular to the first beams and being connected to the ends of the first beams forming a compartment into which a first layer of an insulation is inserted and a pitched roof element for a building roof made of at least two modules, each comprising a frame made of at least first beams being arranged in a distance and running parallel to each other and two second beams running rectangular to the first beams and being connected to the ends of the first beams forming a compartment into which a first layer of an insulation is inserted.

Structural ventilated radiant barrier roofing panels are disclosed. The radiant barrier roofing panels have panel with a first side formed with a plurality of channels and covered with a perforated radiant barrier to form a flow path. When installed on a structure, the radiant barrier roofing panels form a flow path from inside the attic, through the perforations, through the channels, and through abutment spaces between adjacent panels to allow for ventilation of the attic. Methods of ventilating an attic of a structure using radiant barrier roofing panels and of manufacturing radiant barrier roofing panels are also disclosed.

The present disclosure relates to a prefabricated module for a pitched roof element comprising a frame made of at least two first beams being arranged in a distance and running parallel to each other and two second beams running rectangular to the first beams and being connected to the ends of the first beams forming a compartment into which a first layer of an insulation is inserted and a pitched roof element for a building roof made of at least two modules, each comprising a frame made of at least first beams being arranged in a distance and running parallel to each other and two second beams running rectangular to the first beams and being connected to the ends of the first beams forming a compartment into which a first layer of an insulation is inserted.

A panelized building system utilizing structural framing combined with integrated insulation is disclosed. The system may include a roof system, at least one wall panel, a floor panel, at least one corner post and at least one foundational component. The roof system, the wall panel, the floor panel, the corner post and the foundational component are configured to mechanically lock to each to form a panelized building structure consisting of structural framing and composite foam insulation. The roof system, the floor panel, the corner post, and the foundational component of the panelized building system may be configured to mechanically lock to each other through a tongue-and-groove interlocking system.

A seamless sheet installation system preferably includes a seamless sheet and a plurality of sheet retention devices. The seamless sheet is retained on a tube. A pair of rotating retention devices may be inserted into ends of the roll. Each rolling retention device includes a tube plug and a rotating handle. An end of the seamless sheet is secured to the top eave flange. The seamless sheet is held against a bottom of the eave purlin web with one of the plurality of sheet retention devices. The sheet retention device may have any suitable design. The seamless sheet is rolled out to successive purlins, wrapped over the top flange and anchored to a bottom of the vertical web with one of the plurality of sheet retention devices. The seamless sheet wrapping process is terminated at an opposing eave purlin or a ridge purlin. Insulation is then inserted between adjacent purlins.

A method of installing a self-supporting radiant barrier or insulation between roof joists or wall studs secured to an exterior building surface. Flexible and resilient strips are positioned in an inwardly bowed condition between adjacent roof joists or wall studs. A radiant barrier or insulation is positioned between the adjacent roof joists or wall strips in a bowed condition in engagement with the bowed strips. Thereafter, flexible and resilient rods are positioned in a bowed condition in engagement with the roof joists or wall studs, the radiant barrier or insulation and over the bowed strips to secure the radiant barrier or insulation to the underlying bowed strips and the adjacent roof joists or wall studs. The bowed strips, radiant barrier or insulation and the bowed rods are all located within the interior surfaces of the roof joists or wall studs.
