Abstract
Abstract One-piece stud attachments support non-rigid insulation filling the cavities within a wall structure. Each attachment comprises two tongue portions perpendicular to each other. The first tongue portion is screwed or nailed on a wood stud, with the second tongue portion projecting into one of the cavities and penetrating the insulation to support it and prevent slippage thereof downwardly by gravity. The second tongue portion may have spikes, its free end twisted, or a forked free end to hook the insulation. The first tongue portion can also be formed with spikes penetrating the wood of the stud in order to increase the rigidity of fixation. Advantageously, the first tongue portion is made of a strip of metal sheet having its free end half folded over its other half to thereby form a U-shaped, first tongue portion which can be hooked into a hole of a metal stud.
