Affixit Joist Tape is Quick & Easy to Apply and Delivers Instant Acoustic Improvement.

It is applied to the floor joist as an acoustic batten strip. The sound proof joist tape reduces both impact and airborne sound transmission. It can also stop squeaky floors as these squeaks are usually the side effect of there being a gap between the floor joist and sub-floor.

Joist Tape - Stop Squeaky Floors

Do you need to put a Stop to Squeaky Floors? Norton CST™ offers an easy-to-use solution to subfloor squeaks. The squeak is often caused by gaps between the subfloor and the joist. Norton CST™ virtually eliminates squeaks; it leaves a quieter & more comfortable floor.

Impact Sound Transmission (IIC Rating- Impact Insulation Classification) through floors is reduced up to 10 Times!

Airborne Sound Transmission (STC Rating – Sound Transmission Class) through wall is reduced up to 20 Times!
