STC Acoustic Pad™

STC Acoustic Pads™ are 1/4-inch thick neoprene, 1-1/2-inches square. They are easily and quickly adhered to the underside of span-rated plywood. The STC Acoustic Pad™ has been issued US Patent No. 10,041,245.

Pads are generally used to directly support panels. Spacing is determined by deflection.

Pads can also be used in the field of panels and along tongue-and-groove edges at a spacing determined by panel span rating to limit deflection. Pads may be used along terminal edges and at butt edges of panels at a closer spacing; strips are recommended at these locations to eliminate any deflection.

STC Acoustic Pads™ are generally stocked. Please allow 2 weeks to fill and ship your order.

Noise from floors above can travel through the floor structure and radiate into the space below. This is known as impact noise or footfalls, which is measured by a standard called the Impact Insulation Classification (IIC). Different elements of the floor and ceiling construction contribute to isolating this noise in various amounts, and are called the ΔIIC, or Delta IIC (for difference). All dwelling units and sleeping rooms in apartments, condominiums, hotels, and other multiple-unit housing are required by the International Building Code to maintain a IIC-50 (IBC 1207.3).

The STC Acoustic Pad™ helps to prevent impact noise from reaching floors below, and also isolates structure-borne sound as with partitions that extend upward to the structural deck. With identical floor plan layouts there is a very effective sound flanking path into the partition directly above. The STC Acoustic Pad™ system disconnects this sound path since partitions are fastened to the underlayment panel, not the structural deck.

STC Acoustic Pads™ are 1/4-inch thick neoprene, 1-1/2-inch square, and are easily and quickly adhered to the underside of panels. The STC Acoustic Pad™ has been issued US Patent No. 10,041,245.

The STC Acoustic Pad™ system is installed as an acoustic floor covering system over any fire-rated or non-rated floor/ceiling assembly.

The system provides considerable cost savings over acoustical mats and gypsum cement and has a higher ΔIIC-23.
