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. The beams and posts also retain rods inserted through the batts to anchor the edge portions thereof.
