Norton CST™ Joist Tape for Steel Joists

NORTON CST™ (Comfort and Silence Tape) is a patented, uniform gasket that provides a unique noise control and thermal break solution to both residential and commercial construction. It has been successfully used for more than 15 years. NORTON CST™ is a specially formulated closed cell foam tape with pressure sensitive adhesive on one side and a protective durable surface on the other side.

Noise Control
NORTON CST™ virtually eliminates squeaks. It leaves a quieter and more comfortable floor preventing costly callbacks! Thanks to NORTON CST™’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).

Improved Thermal Performance
When used on either one or tw o sides of Steel framing, NORTON CST™ serves as a thermal break that will help lower energy costs.

Condensation
NORTON CST™ does not mold or mildew. By preventing condensation caused by temperature differentials, NORTON CST™ helps eliminate “ghosting” stains that outline metal studs in the wall. Its durability makes it a lifelong value-added to a residential or commercial building.
