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.

Acoustic Sleeper Strips are 1/4-inch thick neoprene, 1-1/2-inch wide and 8 feet long. They are stapled to the underside of span-rated plywood. Patents are pending.
Strips are recommended at terminal edges and butt-edges of panels where floor finishes are brittle or stiff, such as tile or concrete. Strips can also be used anywhere pads are normally used.
Stock and Shipping: Acoustic Sleeper Strips are always stocked. Minimum order is a box of 10 strips, 8 feet long. Please allow 2 weeks to fill and ship. There is no cost for shipping the Acoustic Sleeper.
The Acoustic Sleeper system has a ΔIIC-23, a higher impact insulation classification than acoustical mats and gypsum cement, rubber mats, cellulose panels, and cork. The Acoustic Sleeper pads or strips are paired with a construction panel that has a structural span rating and forms the subfloor such as oriented-strand board (OSB), plywood, cement-bonded particle board, structural cement or magnesia board.
The Acoustic Sleeper allows installation of any type of finish flooring, including hardwood strips, engineered wood, tile (stone, porcelain, ceramic, glass), LVT, vinyl sheet, vinyl plank, vinyl tile, rubber flooring, carpet tile, broadloom carpet or even thin lightweight concrete.
Wood frame construction typically has a single subfloor/sheathing panel. The Acoustic Sleeper system separates the functions with two panels. The sheathing panel is fastened to the structural members to provide diaphragmatic shear resistance. The subfloor panel is supported on top of the sheathing by the Acoustic Sleeper pads or strips, and in line with the structural members. This isolates the transmission of impact vibration while transferring the live loads to the structure. In event of fire, the lower sheathing layer chars and protects the upper subfloor layer so it can continue to carry the structural loads for the required fire resistance. Current UL Designs include:
Non-combustible construction also has a subfloor panel supported on top of the deck by the Acoustic Sleeper pads or strips. It not only provides an exceptional Impact Insulation Classification for footfalls; it also provides isolation from other structure-borne sounds between floors.
Building codes require that fire partitions extend from the top of a fire-rated floor/ceiling assembly (IBC 708.4). The Acoustic Sleeper system is an integral part of 2-hour fire-rated UL Design D902, so instead of extending from the concrete deck, partitions can by placed on top of the panels – they are part of the assembly. This provides a break in the sound flanking path that normally sends noise from televisions or speakers mounted on the partition or floor through the studs and concrete to apartments above and below.
The Acoustic Sleeper has a number of benefits over competitive products
The Acoustic Sleeper is ultimately effective because it creates structural discontinuity. The goal of noise isolation is to keep the material that receives the impact from contacting the actual building structure.
The profile (patent pending) and spacing of the sleepers creates a huge difference between the amount of finish floor area and the amount actually in contact with the structure. For sleeper pads spaced at 24 inches, this means 99.7% of the finish floor area actually floats above the structure, making them superior to options like mats that make continuous contact with the structure.

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.
Acoustic Sleepers are 1-1/2″ wide, 1/4″ high, and are available as pads (1-1/2″ square) and strips (8′ long). They can be easily cut with a knife to any length.
The standard color is black.
Conceptually, the ΔIIC values for the components of the floor/ceiling system should add together to provide the IIC for the system. However, the actual sound transmission values at different frequencies will affect the results. Better estimates can be analyzed if tests from all components are available.
