## Description

Sound, draft, heat, cold, and dust blocking acoustic partition closure and joint filler for interior, non-moving joints and gaps. QuietJoint 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 and blocks sound transmission between rooms. It is colorized, 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 commercial-grade silicone. It is offered in 13 silicone colors, coated on either 2 sides (SHH) or 3 sides (SHG). SHH (two-sided silicone) is ideal for gaps between opaque or solid partitions or walls. SHG (three-sided silicone) 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 aesthetically covers the foam core so that the foam is not visible from the outside through the glass. QuietJoint is supplied in full-story, 10-foot (3-meter) lengths, uncompressed and slightly oversized. The material is compressed by hand and squeezed into the gap or opening. The silicone coating folds at its edges to absorb slight variations in substrates while maintaining a smooth appearance. The internal backpressure of the material mates it to the mullion or other joint faces.

## Features

- For vertical and horizontal-plane joint-gaps from 1/2" (12mm) to 6" (150mm). Made-to-order; typically shipped within ten business days. Supplied in full-story, 10-foot (3 meter) lengths. QuietJoint uses technology covered under U.S. Patent 8,739,495 and patents pending.
- QuietJoint has a minimum STC value of 53 when installed on one side of a partition and a minimum STC value of 72 when installed on both sides. Sound attenuation has been independent laboratory tested to ASTM E90-09, "Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements".
- QuietJoint has an R-value of 2.85 per inch of depth. Insulation value has been independent laboratory tested to ASTM C518-04 "Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus". Smoke and flame spread has been independent laboratory tested to ASTM E84-12: Class A, "Standard Method of Test for Surface Burning Characteristics of Building Materials".
- Clean handling; UV stable; non-staining; low-temperature flexible; high-temperature stable. Non-invasive anchoring allows for rapid installation. Easy to install, thermally insulating, acoustic dampening, all in an economical package.
- QuietJoint is not intended for use in moving joints, and it is not trafficable.
