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.

SUSTAINABILITY: Floor decks composed of wood panels and the STC Acoustic Sleeper neoprene pads have a carbon emissions rate that is 350 times less than decks made of gypsum cement and acoustical mats, 50 times less than decks with rubber mats, and 20 times less than decks with recycled rubber mats. The main factors are the carbon emission rates of gypsum cement compared to wood panels, and the size of rubber mats compared to pads. Also, wood is renewable, which is much more sustainable than even recycled gypsum or recycled rubber.

COMFORT: Shin splints, known as “medial tibial stress,” are shins that ache, and result from footfalls on hard surfaces. Wooden floors are much more comfortable than concrete or gypsum cement because of their resilience, and are much less likely to cause shin splints.
