Watertight Expansion Joints and Construction Sealants by EMSEAL

QuietJoint®

Acoustic Joint Filler and Partition Closure

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.

U.S. Patents

Patent Pending

QuietJoint comes coated on either 2 sides (SHH) or 3 sides (SHG).

SHH (two-sided silicone or STPE) is ideal for gaps between opaque or solid partitions, walls or mullions.

SHG (three-sided silicone or STPE) is typically used to fill gaps between the glass of curtainwall or windows on one side and solid substrates on the other. The third coating covers the foam core so that the foam is not visible from the outside through the glass.

QuietJoint is supplied as either 6.56-foot (2M) or 10-ft (3M) length.

 

 

Over compressing QuietJoint can result in backpressure that could exceed the ability of certain substrates to resist this pressure. User is assumed to have tested all applications to ensure suitability for use.

To preserve a smooth coated-face appearance, the material should not be compressed into joints that are smaller than the nominal size of the product and the installer should be sure to tuck the edges of the coating at the substrate interface.

With SHG the coating is the same color on all three faces.

Not intended for use in moving joints. Not trafficable. For watertight, moving structural joint gaps see EMSEAL Product and Application Index.
