Acoustic Sleepers

The STC Acoustic Sleeper helps to prevent impact noise from reaching floors below.

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). Acoustic sleeper strips are recommended at terminal edges and butt-edges of panels. Use acoustic sleeper pads in the field of panels and at tongue-in-groove edges.
