Eliminate Sub Floor Squeaks & Reduce Sound Transmission with CST Green Glue Joist Tape
Norton CST (Comfort and Silence Tape) is a uniform gasket joist tape that provides a unique noise control and thermal break solution to both residential and commercial construction.
It is a specially formulated closed cell foam adhesive tape with pressure sensitive adhesive on one side and a protective durable surface on the other side.
Noise Control NORTON CST™ Joist Tape virtually eliminates squeaks. It leaves a quieter and more comfortable floor due to it’s ability to dampen vibrations:
Impact sound transmission (IIC rating - Impact Insulation Classification) through floors is reduced up to 10 times! (ASTM E-989).
Airborne sound transmission (STC rating - Sound Transmission Class) through walls is reduced up to 20 times! (ASTM E-90).
