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, non-invasively anchored closure that mates mullions to partitions, windows, or stud walls and seals off sound transmission between rooms. 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 is designed to block the spread of sound to other rooms or areas by filling partition or wall openings and overlooked building element junctures. For vertical and horizontal-plane joint-gaps from 1/2" (12mm) to 6" (150mm). 26 Standard Silicone Colors, custom colors, non-invasive anchoring, thermally insulating, acoustic dampening, rapid installation, economical. Self-extinguishing, fire-retardant-acrylic-impregnated foam, factory pre-coated with high-quality silicone. Clean handling, UV stable, non-staining, low temperature flexible, high-temperature stable. Supplied in full-story, 10-foot lengths, uncompressed and slightly oversized, material is compressed by hand and squeezed into the gap or opening. The material 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. Sound Attenuation--Independent laboratory tested to control passage of air-borne sound.
Insulation Value--Control HVAC balance and energy loss between roomsThe R-value of QuietJoint foam is R-2.848/inch of depth. Depending on the joint size and related depth, the R-value of the material will be:
