The Box Seal is a wall plate gasket that serves as an acoustic wall plate seal and fire prevention measure, effectively plugging spaces around wall outlets.
The STC Hi-Sabin Panel controls reverberant noise due to exposed ceilings, and offers more savings than other types of sound absorption panels.
The STC Acoustic Sleeper helps to prevent impact noise from reaching floors below.
The STC Mullion Seal closes the gap between a window and wall partition to stop sound from traveling trough these spaces.
If you've ever stayed in a hotel or hospital, you've probably experienced noise traveling from the rooms on either side of you. Sound isolation measures help to control noise between adjacent rooms by preventing sound from flowing through openings like outlets and vents.

Many sound issues stem from a lack of sound control within one room or space. Reverberation control measures limit the amount of time that sound lingers in that space—eliminating issues like echoes. From the size of the room to the surfaces in it, we can tailor solutions to minimize reverberation.
When someone moves around above the ground floor of a building, noise can travel to the floor below. Known as impact noise or footfalls, this type of sound can be minimized with products that go between a floor and the ceiling below it to prevent sound from carrying.
Most of the time, we ignore sound until it becomes a problem. But once it does, it’s often a big one. From hospitals and dormitories to restaurants and office spaces, noise can affect productivity, customer satisfaction and overall success. Whether it’s sound that’s finding its way between rooms, lingering within one room or traveling between floors to the space below, we create noise reduction solutions to make complaints and inconvenience a thing of the past. Problems We Solve >>
STC’s unique noise control products are simple, cost-effective and high performing for developers and architects. And perhaps more importantly, they help customers’ and end-users’ acoustical comfort-fixing issues from complaining hotel guests to office workers desperate for a little privacy.

For recessed outlets
starting at $192.00
$3.50 per seal
Increased performance by seven decibels in a hotel with five outlets.
Wiring Devices as a Wall Plate Gasket.
Neoprene, a dense and resilient rubber selected for its ability to isolate vibrations through viscous damping. It is also specially compounded to be Class A fire-rated per ASTM E119.
Performance will always improve by at least 2-3 dB with the Box Seal and as much as 7 dB. The amount is affected by the STC rating of the partition, number of outlets, and the presence of sound attenuation blankets or putty pads.
Yes. The Box Seal spans the wall opening just like the wall plate so that it occupies no space inside the electrical box. Specifically, the requirements of Section 314.16 are unaffected by use of the Box Seal.
The Box Seals is certified by Underwriters Laboratories as a wall-opening protective material and listed in the UL Fire Resistance Directory.

Hi-Sabin Panel Spacing Comparison 2-inch Flat Panels
Sound Absorbing Ceiling Units
Basotect® by BASF, an open-cell low-density melamine-based foam that has extraordinary sound absorption characteristics. Basotect® has a Class A fire-rating per ASTM E84 with a flame spread index of 5 and smoke-developed index of 0.
Yes. Section 2603.3 requires foam plastic cores of manufactured assemblies to have a flame spread index of not more than 75 and a smoke-developed index of not more than 450. In addition, panels are tested per UL 94 for flammability of plastic material and demonstrate Class V-0, and for low density foam HF-1. Basotect® is so fire resistive it is used for fire protection.
Best acoustical results and economy are achieved with Furred and Spaced Type J mounting per ASTM E795 utilizing hot melt adhesive and foam standoff mounts. Panels can also be Direct Attached Type A, Suspended Type E or Furred and Butted Type F-50.

Sheathing as an Acoustic Underlayment System
Neoprene, a dense and resilient rubber selected for its ability to isolate vibrations.
A critical goal of isolating impact noise is to minimize contact between the finish floor surface and the supporting structure. More than 99.2% of the floor area actually floats on air with Acoustic Sleeper installations; continuous mat systems don’t do that.
Yes. The Acoustic Sleeper is made of solid neoprene rubber, not wood, and IBC Section 718.2.7 does not apply. Independent tests per ASTM E2179 of sleeper pads at 24-inches under plywood performed at ΔIIC-18 and is a major component of the Impact Insulation Classification of floor systems to comply with IBC Section 1207.3. When used over a concrete deck it achieves IIC-46 even before a finish floor or ceiling is added to the underlayment system.
Partition joints at window walls
The Mullion Seal prevents sound from passing through that troublesome juncture of a partition with a curtainwall mullion at a glazed exterior wall.

Mullion Seal Transmission Loss
Gypsum Board in the Auxiliary Material article as a performed seal at mullions
Neoprene, a dense and resilient rubber selected for its ability to isolate sound and vibrations. Neoprene also remains extremely flexible and does not deteriorate with exposure to ultraviolet light.
No. The interior partition that sits on the floor, and the mullion that is connected to the exterior wall, are allowed to move in relation to each other. Offset pressure sensitive adhesive strips (PSA) connect the Mullion Seal to both the partition and the mullion.
Prior to constructing the partition at the mullion cut the flat profile seals to length. Short leftover pieces may be butted together. Remove the protective cover on the mullion-side PSA strip (keep the cover on the wall-side PSA during this step), set in place and apply pressure. Prepare a small pre-finished section of partition, usually of the same depth as the spandrel shelf, complete with corner trim and compound, perhaps even sanded and painted. Remove the PSA cover strip from the partition side of the seal and immediately set the prepared section of partition in place, applying pressure to set the adhesive.
Custom cove profile will require trimming of the cove edge where it passes by horizontal mullions including top, bottom and any intermediates.
