A roof system and related methods for installing the roof system. The roof system includes a roof diaphragm including a nail board and an insulating panel connected to the nail board, wherein the insulating panel is adapted to be positioned between the nail board and a roof frame so that the insulating panel engages the roof frame. In several exemplary embodiments, the nail board comprises one or both of: oriented strand board (OSB) and plywood. In several exemplary embodiments, the insulating panel comprises one or both of: a closed-cell rigid polyisocyanurate (polyiso) foam core and a polystyrene foam core. In several exemplary embodiments, the roof system further includes a plurality of nail board fasteners connecting the roof diaphragm to the roof frame, the nail board fasteners each extending through the nail board, through the insulating panel, and into the roof frame to a depth.

A wall panel system includes a first wall panel, a second wall panel, and a joint member that couples the first wall panel to the second wall panel. The wall panel system also includes an upper mounting assembly that couples to the first wall panel and the second wall panel such that the upper mounting assembly pivots with the first wall panel and the second wall panel.

Implementations of the present invention provide systems, methods, and apparatus for securing trim to interior and/or exterior walls and wall portions. In particular, at least one implementation includes a system for connecting and securing trim elements without additional adjustments and/or fitting thereof. Moreover, the system for connecting and securing trim elements can improve accuracy and increase the speed of assembly, thereby reducing time and expense associated with installing trim to a building.

A building panel may be installed below a slab in the construction of buildings. The building panel supports the slab and also provides a ventilation layer that may be depressurized to eliminate or reduce infiltration of radon gas into the building. The ventilation layer may comprise channels which provide a two-dimensionally interconnected void. Ventilation panels which include collars for connecting to ventilation systems may be provided. The panels may be installed directly on compacted soil. The building panels may additionally provide sub-slab insulation and/or a capillary break for water drainage. In some embodiments the building panels are formed substantially entirely of thermal insulating material such as rigid polystyrene foam. In an example embodiment the panels are approximately 4 inches thick and have a grid of intersecting channels formed on an underside of the panels.

The invention is related to a masonry reinforcement and to a dispenser therefore. The masonry reinforcement comprises a reinforcement strip that defines a strip plane and that is at least in one direction bendable. In the reinforcement strip multiple strip apertures are arranged along the longitudinal direction of the strip, each strip aperture comprising an aperture rim at the aperture rim or in the range of the aperture rim of some or all of the strip apertures rim serration members are arranged. The rim serration members are orientated inwardly. They can protrude out of the strip plane of the reinforcement strip in at least one direction.

The present disclosure concerns a flexible thermal insulation assembly to thermally insulate matter from an external environment, the flexible thermal insulation assembly comprising a plurality of thermal insulation covering sections comprising an outer layer and an insulated matter-facing layer, the plurality of thermal insulation covering sections being configurable in an adjacent configuration wherein the plurality of thermal insulation covering sections are articulately connected to one another to substantially conform to an outer surface of the insulated matter; and an insulated matter-mounting assembly securing the plurality of thermal insulation covering sections onto the insulated matter with the insulated matter-facing layers of the plurality of thermal insulation covering sections at least partially covering the insulated matter and substantially conforming thereto. The present disclosure also concerns a method for thermally insulating matter, such as a snow heap, from an external environment.

Building structures can be fabricated at an offsite, and then assembled at the construction site. The building structures can include beams and wall panels having metal attachments. The beams and wall panels can be assembled by coupling the metal attachments, for example, by welding.

A building-construction panel includes a tongue on one edge and a groove on an opposite edge that receives the tongue of an adjacent panel. A shoulder on the tongue-side edge defines an abutted surface that is contacted by an abutting surface on the groove-side edge to limit panel travel during installation and maintain a gap between upper edge portions of the adjacent panels. A bottom transition is formed on the groove-side edge so that the groove-side abutting surface is smaller than the tongue-side shoulder abutted surface. In this way, the relatively smaller groove-side abutting surface structurally maintains the gap but also minimizes frictional interpanel contact area to minimize squeaking. And the relatively larger tongue-side shoulder abutted surface helps keep the shoulder from being collapsed into the groove from overdriving the panels together during installation. In typical embodiments, the panel is a high-performance structural wood subflooring panel.

Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.
