Abstract: Studs and plates used to retain compressible insulating panels against sagging in a hollow wall. Also, bars for securing rigid insulating panels in a wall. All of these elements are made of sheet metal and include struck-out prongs defining a similarly-shaped opening in the sheet metal. These prongs are elongated, with a pointed face end and teeth laterally projecting from one side. The inner end of each prong is integrally retained to the sheet metal and the prong can be bent into an operative position, normal to the sheet metal from an inoperative position nearly parallel to the sheet metal. A stop protrudes from the prong at the bending line to abut the sheet metal and maintain the prong in its operative position. The prong, in its inoperative position, protruding from one side of the sheet metal and offset with respect to the opening in the sheet metal, such as that it can be bent through said opening. Therefore, the user cannot bend the prong in the wrong direction.

Abstract: A metal stud for building walls, of substantially cross-sectionally U-shape, defining a channel, and that has integral jagged finger-shaped portions or prongs punched out of the web of the stud and which can be bent transversely to the web immediately prior to use, to enable impaling and anchoring of glassfiber-insulating batts, so as to support and retain the latter in place between the studs. The studs may be posts, ceiling joists, or transverse beams. The prongs preferably include a few barbs along a longitudinal edge, so as to contribute in the anchoring of the insulating batts to the studs. The prongs of the posts, when bent, are inclined relative to the web, so as to extend at an angle through the batt and, thus, across several of the easily-separable layers of fibers constituting said batts. Similar prongs are provided in horizontal beams interconnecting the posts. The barbs are also transversely upwardly inclined for easier and better anchoring.

Abstract: A combination fascia and G-trim moulding is disclosed comprising, firstly, a J-trim moulding in two pieces each having a generally L-shaped profile singly and a U-shaped profile when secured together; and, secondly, a fascia moulding having a vertical portion and a horizontal portion, the latter having a downwardly extending flange at its free edge; the flange engaging a longitudinally extending deep slot formed in the attaching branch of the upper piece of the J-trim.

Abstract: An attaching device to secure soffits under the eaves of a roof and to cover their ends. The attaching device is made of two separate pieces with snap action interlocking means. A top piece is first secured to the eaves and, once the soffit is fitted and retained to the eaves, the bottom piece is interlocked with the top piece. The bottom piece has a plate part extending under the soffit. The same attaching device may be used to secure sidings on the outside walls of buildings.
