A through-wall flashing support system for supporting a through-wall flashing membrane installed in a cavity wall. The system includes multiple support parts, multiple spline parts and a through-wall flashing membrane. Each support part has a flange, configured to abut and be attached to an inner wall of the cavity wall, and a base, extending with a downward slope from the lower portion of the flange such that the outer portion of the base penetrates an outer wall of cavity wall. Spline parts are configured to connect adjacent support parts. The through-wall flashing membrane extends across the cavity and covers the bases of the support parts and the spline parts. Weep holes are installed to enable water to flow through the outer wall along through-wall flashing membrane. Methods for installing this system in a new cavity wall and retrofitting an existing cavity wall are also provided.

Self-standing, thermally-insulating, noise-insulating, seismically-insulating, water-insulating, electromagnetic-insulating superstructure, whose overall internal volume is filled with rigid and lightweight granules, in which the dwelling rooms are immersed. The lightweight granules are spherical, porous or hollow, they have no binder and are scattered. A gas-tight skin clads all the outer surface of the superstructure's shell and the walls of the dwelling quarters. Gas-tight bay-frames of conical outer shape are embedded in the openings and bays. The entire volume, made up of the scattered granules, the plates, the bay-frames and the gas-tight skin, is under gas-vacuum. This gas-vacuum is lifetime-controlled by a vacuum pump which is installed in situ. The outer casing and the inner walls are braced by the volume of granules stiffened by atmospheric pressure. A plurality of ion-polarized layers, vaporized on overlay metallized polymer vacuum sheets, are inserted between the rigid plates and the gasproof skin.

Aspects of the disclosure relate to building envelope assemblies including a structural wall frame, a water separation plane on an exterior side of the structural wall frame, an opening in the building envelope assembly and an envelope penetrating component positioned within the opening and secured to the structural wall frame. Additional aspects relate to a drain assembly that can be provided as part of the building envelope assembly or provided separately. The drain assembly incudes first and second plates, moisture inlet and outlet, a flexible sheet disposed between the first and second plates and extending between the moisture inlet and outlet and at least one seal formed between the moisture inlet and outlet, each seal adjacent the flexible sheet. The drain assembly is configured to transport moisture from the moisture inlet to the moisture outlet.

A system for a basement concrete form and drainage are disclosed. The system may include a lineal that is a horizontal concrete form for a footer for a wall and a basement floor. The lineal may include a rectilinear tubular structure having a cavity, an outer wall, and drain perforations in the outer wall to permit fluid transmission from the cavity to an exterior of the lineal. In addition, a retainer may be mounted to a stake for the basement concrete form when the stake is embedded in a formation underlying the lineal. The retainer may be selectively vertically positioned along the stake to adjust a height of the lineal relative to the underlying formation.

A moisture barrier system, comprising a barrier sheet adapted to be installed on a building having an interior wall structure and an exterior wall structure spaced apart from the interior wall structure to define a cavity there between.

A damp proof course article (20) for forming a damp proof course in a substrate (10) is disclosed. The damp proof course article comprises an absorbent member (22) and a damp proof course material absorbed into the absorbent member. The damp proof course material comprises an active agent, wherein the active agent comprises an alkoxysilane.

There is disclosed a system and method for wall panel trim installation. In an embodiment, the system comprises a plurality of horizontal and vertical trim profiles having a back plate adapted to receive a top cap within a bracket, the bracket including a mounting base and walls extending up from either side of the base; and at least one flange formed on the walls and extending outwardly, the at least one flange including a shallow channel; wherein, upon receiving the top cap within the bracket, the at least one flange forming the shallow channel and a portion of the top cap secure an edge of a wall panel therebetween. In an embodiment, the shallow channel formed within the at least one flange is adapted to receive an adhesive or sealant. The top cap is partially received within the bracket such that a clearance is formed between a bottom of the mounting base and a bottom of the top cap. Back plate and top cap pairs allow installation of wall panels placed into position without fasteners.

A ventilating sill for elevating a wall partition from a floor surface in order to isolate the wall partition from moisture and humidity that can emanate from the floor surface or be present thereon. The ventilating sill includes a block having a support surface, a base surface, two opposed side surfaces and a plurality of spaced channels extending between the side surfaces forming channeled surfaces. The ventilating sill further includes a pair of slats, each slat extending from each side surface upwardly towards the wall partition at a right angle to the support surface, the slats defining a support area, and being adapted to guide the wall partition onto the support surface and at least one aperture communicating between the support area and an ambient environment for ventilating the support area and draining moisture and humidity therefrom.

A device for insulating the slab foundation of a building, said device comprising: a generally horizontal insulating section disposed between the slab foundation and a footer of a building, said horizontally disposed insulating section comprising a generally elongated cuboid shape having at least one cutout through which a concrete column is disposed; said prefabricated device further comprising a generally vertical insulating section disposed adjacent to said horizontal insulating section and attached to said building.

A building sub-floor construction comprising a plurality of elongated beams formed of rigid polymer foam material, wherein the elongated beams comprise similar cross-sectional shapes, and wherein the elongated beams are configured to snuggly engage one another along their lengths to produce a continuous slab.
