QuietJoint -- Partition Closure & Sound Blocking, Flanking Path Filler

 

STC-53, OITC-38, R-Value 2.85/in


QuietJoint SHG, two-sided, sound attenuating joint filler from EMSEAL.

QuietJoint-SHH is coated on two faces and is ideal for gaps between opaque or solid partitions or walls. The coating can be the same color on both faces or different on each face to coordinate with wall coverings.

QuietJoint SHG, three-sided acoustic seal for glass from EMSEAL

QuietJoint-SHG is coated on a third face and 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 through the glass. The coating can be the same color on all three faces or different on each face to coordinate with wall coverings. (Note: color transitions between different faces may blur).

ABOVE: QuietJoint SHG installed between window glass and end of wall partition. The third silicone side faces the glass. The silicone color of this sample is Dow 790 Sandstone and was chosen deliberately to contrast with the surrounding colors. The image above was shot with a short piece of QuietJoint for illustration purposes. In reality the 10-LF supply lengths (seen below) allow installation in the entire run without any joins.

Color-switching can be used with QuietJoint to coordinate with bands of color in a wall's color scheme. In the example above, the Dow 790 Bronze silicone was chosen to best blend with the metal window mullion. 26 sealant face colors are available

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. C
lean 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.

Insulation Value--Control HVAC balance and energy loss between rooms

The 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:

Material R-Value
(installed one side of joint)
R-Value
(installed both sides of joint)
1/2" to 4.75" with 2" depth
(12mm to 120mm with 50mm depth)
5.696 11.39+*
5" to 6" wide with 3-inch depth
(125mm to 150mm with 75mm depth)
8.544 17.088+*

*Assumes installation from both sides of the wall thereby doubling the R-value. The inclusion of an air gap between the two pieces of QuietJoint will add additional insulation, effectively more than doubling the R-value.

Independent laboratory tested to ASTM C518-04 "Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus".

Material Sizing:

QuietJoint is available in 1/4-inch (6mm) increments for field-measured joint openings in widths from 1/2" (12mm) up to 6-inches (150mm) with depths according to the following chart:

Joint Sizes Depth of Seal Length
1/2 - 4.75"
(12 - 120mm)
2"
(50mm)
10-ft
(3 meters)
5 - 6"
(125 - 150mm)
3"
(75mm)
10-ft
(3 meters)

Material Configurations--Double and triple-sided options

QuietJoint-SHH is coated on two faces and is ideal for gaps between opaque or solid partitions or walls. The coating can be the same color on both faces or different on each face to coordinate with wall coverings.

QuietJoint-SHG is coated on a third face and 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 through the glass. The coating can be the same color on all three faces or different on each face to coordinate with wall coverings. (Note: color transitions between different faces may blur).


Limitations:

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.

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