Sound Absorption Panels

Description and Application

Kinetics Model S-4 is a highly efficient, tuned sound absorber designed for low and midfrequency sound absorption.

Model S-4 consists of a 3 PCF (48 kg per cu. M) glass fiber core completely protected with a eight mil (203.2 micron) thick neoprene-coated, fiberglass reinforced, aluminized polyester white or foil film (1.5 mil/38.1 mircon) facing.

The product is available in 1" (25 mm) and 2" (50 mm) thicknesses, and sizes up to 4' by 8' (1219 mm x 2438 mm), or in die-cut shapes to meet application requirements. When tested in #4 mounting (direct application), the 1" (25 mm) thick S-4 sound absorber is rated at NRC 0.75. The 2" (50 mm) thick S-4 is rated at NRC 0.94.

Kinetics Model S-4 Sound Absorbers are particularly suited for wall or ceiling installations in industrial facilities and machinery enclosures, engine shrouds, air compressor cabinets or other applications where a reduction of reverberated sound is desirable.

Kinetics Model S4 Sound Absorpers

The board-like absorbers have good structural integrity and damage resistance and can be used in temperatures from -65F to 265F (-54C to 129C).

The highly reflective surface and flame resistant properties of the facing material make it ideal for most applications where sound absorption is required. Fire Hazard Classification: flame spread 25, smoke developed 50.

Kinetics Model S-4 Sound Absorbers can be installed by impaling them on welded pins, by cementing, or by using edge clips or batten strips. S-4 Absorbers can be steam cleaned and are designed to resist most conditions which are found inside machinery enclosures.
