A sealing strip is for sealing drywall connecting joints. The sealing strip has a centre web with two longitudinal edges, wherein along each longitudinal edge, a sealing profile is arranged having a first profile section, which is arranged along the allocated longitudinal edge and has a first thickness in the transverse direction of the centre web. A second profile section adjoins the first profile section, and the second profile section forms the end of the sealing profile that is remote from the centre web and has a second thickness in the transverse direction of the centre web, the second thickness being smaller than the first thickness.

A system for sealing a space defined between a modular wall and a permanent structure includes a sealing material connected to the permanent structure and the modular wall and spanning the space defined therebetween. The sealing material is configured to transform from an expanded state to a recovered state in response to a stimulus to form a seal. The stimulus can be, for example, heat, whereby heating the sealing material at or above the transition temperature for the sealing material causes the sealing material to transition from the expanded state to the recovered state.

A joint tape to be applied to wallboard is provided and includes a base substrate having opposing sides. In certain embodiments, a first adhesive layer is applied to one of the sides of the base substrate and a second adhesive layer is applied to the first adhesive layer, where the first adhesive layer is different than the second adhesive layer. In certain other embodiments, two different adhesives are used in a single adhesive layer. In use, the joint tape is positioned over and removably secured to a joint or corner between adjacent wallboard panels using the first adhesive layer. After the joint tape is in position, joint compound is applied to the joint tape, and the water in the joint tape activates it to form a secure bond with the wallboard panels.

In one embodiment, a system comprises a first baseboard element, a second baseboard element, and a spline configured to couple with the first baseboard element and the second baseboard element. In another embodiment, a system comprises a first crown element, a second crown element, and a spline configured to couple with the first crown element and the second crown element. In another embodiment, a system comprises a crown spline, a baseboard spline, and a wall element configured to be coupled with the crown spline and the baseboard spline. Other embodiments are disclosed herein.

Embodiments of the invention provide a corner guard and a wall guard, and a method of installing the corner guard and a wall guard that reduces the installation time and provides an improved aesthetic appearance. A corner guard and a wall guard each includes an elongated cover member that is terminated at one end, or both ends, by an end cap. The end cap is sonically welded or otherwise adhered directly to the cover member rather than being attached separately to an underlying base member. The cover member with end cap can then be slid on or snapped onto the underlying base member together.

A non-swelling joint tape for use with drywall applications includes a tapered trim strip body extending along a central body axis and a non-swelling backing paper. The tapered trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a first dimensionally stable material. The non-swelling backing paper is at least partially secured to the second surface of the tapered trim strip body and is at least partially constructed from a second dimensionally stable material. The tapered trim strip body is dimensioned such that a first thickness between the first surface and the second surface at the central body axis is greater than a second thickness between the first surface and the second surface at the first side and the second side.

A composite structural board having a structural board and a water-resistant barrier (WRB) sheet, and a wall system comprising same, wherein a face of the structural board is discontinuously attached to the inner face of the WRB sheet solely by a first adhesive, the WRB sheet fully covering the face of the structural board; wherein the unattached areas between the face of the structural board and the inner face of the WRB sheet define paths by which a liquid can move between the face of the structural board and the inner face of the WRB sheet; in some instances the WRB sheet material extends beyond at least one edge of the structural board forming a WRB sheet flap.

A process for covering, protecting and providing access to mate lines during building construction comprising the steps of preparing a vertical and horizontal mate line closure flap, carrying out a vertical and horizontal mate line access process, carrying out a vertical and horizontal mate line closing process, repeating the vertical and horizontal mate line access and closing processes as required, and carrying out a vertical and horizontal mate line sealing process to complete the building weatherization.

A construction element is provided for forming a corner of a surface of a building, the surface including wall panels attached to framing studs. The construction element includes: a corner-forming surface that that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels; and a fastener strip that, in a state in which the corner-forming surface is in its installed position with respect to the framing studs, is substantially parallel to one or more of the framing studs, such that a fastener can attach the fastener strip to one or more of the studs without passing through the wall panel.

A wall surfacing system for providing a secondary ceiling or wall covering structure adjacent a primary structure. The system provides a plurality of elongated structural support rails, each of these support rails have a coupling web with a bearing surface for attachment to the primary structure, a coupling mechanism, and a portion integrally formed with and connecting the coupling web to the coupling mechanism. A plurality of generally planar surface panels are provided. Each panel has an integral interlocking member configured to mate with the coupling mechanism on the support rail. The elongated support rails are secured to primary structures, thereby extending the surface panels to form an aesthetically pleasing covered surface.
