Acoustic Sleeper Strips are 1/4-inch thick neoprene, 1-1/2-inch wide, and 44 inches long. They are stapled to the underside of span-rated plywood. The Acoustic Sleeper has been granted US Patent No. 10,041,245.
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.
Acoustic Sleeper Strips are always stocked. The minimum order is a box of 10 strips, 44 inches long.
*Please allow 2 weeks to fill and ship your order. There is no cost for shipping the Acoustic Sleeper Strips within US-48.
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 Sleeper 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 Acoustic Sleeper system disconnects this sound path since partitions are fastened to the underlayment panel, not the structural deck.
Acoustic Sleeper pads and strips are 1/8-inch thick neoprene, 1-1/2-inch wide, and are easily and quickly stapled to the underside of span-rated plywood. Patents are pending.
The Acoustic Sleeper is an integral part of fire-resistance rated floor/ceiling assembly UL Design L563, System 1. It is currently rated for 30 minutes, ideal for 5-story Type III-B construction and Type V-B of 3 stories. The 30-minute rating is all that is needed to protect dwelling units and sleeping rooms per IBC 7188.8.131.52. The system provides considerable cost savings over acoustical mats and gypsum cement and has a higher ΔIIC-18.
In addition to providing impact isolation, the Acoustic Sleeper system isolates structure-borne sound that enters a partition in a lower space from flanking into the space above. Typical fire-rated partitions extend to the structural deck; identical floor plan layouts place another partition directly above, also firmly attached to the deck, completing a very effective sound flanking path. With the Acoustic Sleeper system, partitions are fastened to the underlayment panel, not the structural deck, effectively disconnecting this sound path.
