An acoustic joint filler, QuietJoint is a mass-loaded sound, draft, heat, cold, and dust blocking acoustic partition closure and joint filler for interior, non-moving joints and gaps.It is a non-mechanical, high-STC (Sound Transmission Class), non-invasively anchored closure that quickly and easily mates partitions to windows, mullions, or stud walls.
QuietJoint blocks sound transmission between rooms. It comes in colors, is versatile, and ideally suited as a closure for gaps between the ends of permanent, semi-permanent, or movable partitions, window-wall, curtain-wall, head-of-wall and other conditions.
QuietJoint features a mass-loaded fire-resistant foam core coated with a high-grade silicone. The foam core is a custom-density open-cell foam infused with a fire-resistant, acrylic-based mass-loading agent.
Supplied just larger than the field-measured joint gap, QuietJoint is hand compressed and squeezed into the opening. The edges of the outer coating are tucked tight to the substrate to complete a clean finish.
SHH (two-sided silicone or STPE) is ideal for gaps between opaque or solid partitions, walls or mullions.
