Green Glue Joist Tape is applied directly to the top of the floor joists with the adhesive side down. The Joist Tape can be applied by hand for medium to small jobs. For large and recurring jobs, a joist tape applicator is available for purchase from many of our distributors.
The Joist Tape is sold in widths to fit standard joist sizes: 1-7/16”, 2-1/4”, and 3”, and are 1/8” thick and 100 feet in length ( 3.6, 5.7 and 7.6cm and 30m in length).
Joist Tape is only used to address the noise from squeaks when the subfloor rubs onto the joists. If you need additional sound reduction, consider the compound or clip solutions.
