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. The construction element may be provided in multiple sections that are placed end to end and connected together.

A ventilation member includes a base panel for mounting onto a substrate, an upper panel extending transversely from the base panel, a lower panel spaced apart from the upper panel, and an inner panel extending transversely from the lower panel. A passageway is defined having a first portion defined between the base panel and the inner panel and a second portion extending transversely from the first portion and being defined between the upper and the lower panel. When used as part of a system, the ventilation member may be an upper ventilation member and the system may include a second lower ventilation member including a base panel and a leg extending transversely thereof.

The A joint and covering assembly for panels covering floors and having a covering profile having at least one extension with a hidden face arranged facing the floor and an exposed face arranged visible; a base profile with a resting face to make contact with the floor and a supporting face arranged facing the hidden face; and coupling elements between the profiles, having two coupling portions according to different angles with respect to the resting face, and an attachable element coupled in the portions, the attachable element B) projecting from the hidden face. The coupled arrangement is established such that the exposed face has a different inclination with respect to the resting face according to the portion.

A wallboard-fastening device for securing first and second wallboards to a framing member in an outside-corner configuration includes: first and second framing panels that connect to each other to form an inner corner seam that fits against the framing member; first and second corner panels that connect to each other to form an outer corner seam; a first bridge panel that connects to (i) the first corner panel to form a first outer seam and (ii) the inner corner seam; a second bridge panel that connects to (i) the second corner panel to form a second outer seam and (ii) the inner corner seam; a first flat-spring flange that connects to the first outer seam to form a first channel sized to accept the first wallboard; and a second flat-spring flange that connects to the second outer seam to form a second channel sized to accept the second wallboard.

Modular Construction elements are characterized by a variety of profiles and associated interchangeable components and/or inserts. Together, these structures and components allow the end user to incorporate dissimilar or similar materials having a wide range of thicknesses and geometries into a flanged associated with the construction elements and tailored to its particular profile. Through the use of a unique set of interconnection methods and systems, a relatively small set of elements can be arranged to protect the surfaces of a wide array of interior surface treatments and the intersections of those surfaces. Dimensional material can be configured to provide the desired form of intersection and transition type—e.g., horizontally to horizontally, horizontal to vertically, vertical to vertical, vertically to horizontally, and the like—while at the same time creating and maintaining a sealed, sanitary and watertight condition within a specified area.

A ventilation screed comprising: an attachment flange having a top portion and a bottom portion; a drip edge protruding from the attachment flange and a return leg that protrudes back from the drip edge, wherein the drip edge is angled downward in a first direction and the return leg is angled downward in a second direction; a drainage cavity protrusion protruding from the attachment flange above the drip edge, wherein the drainage cavity protrusion has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion and a substantially vertical portion with a top end and a bottom end in communication with the bottom portion, an upper ground portion in communication with the top end of the substantially vertical portion of the L-shaped drainage trough portion extending outward from the substantially vertical portion and a drainage cavity shroud extending substantially downward from the upper ground portion.

An installation kit for the production of a niche includes a recess element including a rear wall, four side walls and a projecting frame adjoining outward edges of the side walls and extending away from a niche. At least one of the side walls includes a passage opening formed therein. An insert can be insertable into the passage opening of the side wall on the niche side, the insert defining a recessed receiving space accessible on the niche side of the side wall, the insert including an opening opposing the receiving space. At least one cover can be receivable within the insert to at least partially cover the receiving space, the cover being positionable substantially flush with the side wall.

There is disclosed an improved wall panel trim reveal system and method which utilizes a set of vertical, horizontal and corner trim pieces designed to be fitted together. In an embodiment, the system includes horizontal trim pieces having at least one slope, vertical trim pieces having at least one tab forming a slot for receiving one or more horizontal trim pieces therein, wherein the horizontal and vertical trim pieces when installed together with wall panels forming a moisture drainage channel to direct moisture away from the wall.

A precast cladding panel has upper and lower edges that, as viewed in transverse vertical cross-section through the panel, are profiled for overlapping engagement with complementarily-profiled edges of vertically-adjacent cladding panels in a coplanar cladding panel assembly mounted to a supporting structure. The upper edge of the panel defines a convex horizontal ridge, and the lower edge of the panel defines a concave horizontal recess, such that the convex horizontal ridge on the upper edge of one panel will project into the concave recess of the lower edge of a similar panel mounted immediately above it. The convex configuration of the upper edge of the panel promotes drainage of water out of horizontal joints between panels in the mounted assembly of cladding panels, and the overlapping engagement of vertically-adjacent panels impedes or prevents the entry of wind-driven rain into the cladding structure via the horizontal joints between panels.
