QuietJoint is a 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. It also provides a fire resistant acoustic barrier in joints and gaps, where it blocks sound transmission between rooms.

Features and benefits:

Surface coloured.
Features a mass-loaded fire-resistant foam core coated with commercial-grade silicone. The foam core is a custom-density open-cell foam infused with a fire-resistant, acrylic-based mass-loading agent.
Mass-loaded acoustic seal (STC-53, OITC-38, ASTM E-90).
Fire-resistant (Smoke and Flame Spread Class A, ASTM E-84-12).
Insulates (R-value 2.85/in depth, ASTM C-518-04).
Sound attenuating.
Non-mechanical.
Non-metallic.
Rapid installation-new or retrofit.
Non-invasive anchoring.
Practical and versatile.
Easily handles curves.
Helps control HVAC balance between rooms.
Available in many industry standard colours and custom colours (3-sided SHG is manufactured with the same colour on all three sides).
Also available in a paintable STPE sealant coating in a single neutral “limestone” colour ideal for accepting latex and acrylic paints and coatings on the exposed face.
Comes coated on either 2 sides (SHH) or 3 sides (SHG).

Configuration:

SHH (two-sided silicone or paintable STPE) is suitable for gaps between opaque or solid partitions, walls or mullions.
SHG (three-sided silicone or paintable 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 aesthetically covers the foam core so that the foam is not visible from the outside through the glass
