One of the biggest noise complaints is the sound of footsteps and squeaky floors. The squeaking that’s driving you crazy occurs naturally when floors settle, and joists rub together with subflooring. There’s an easy solution: Joist Gasket Tape. The tape creates an airtight seal and dampens foot traffic, so that annoying squeaking becomes a thing of the past.

About Joist Gasketing Tape:

Our Gasket Tape installs on walls, ceilings and floor joists to enhance overall sound isolation. Floor squeaks develop when floor boards rub against floor joists, the tape installed on the joists will insure that these squeaks never develop in the first place. It is also a formulated gasket that provides a uniform layer between the framing members and surface materials to reduce impact sound transmission through floors and walls and to reduce floor vibration.

How it Works:

Gasket Tape is composed of a closed-cell PVC material with a strong adhesive on the bottom and a smooth, durable Mylar Top. Gasket Tape offers the latest technology in construction to increase IIC Value and reduce vibrations and squeaks.

Reduce Vibrations: The low density of the Gasket Tape effectively reduces impact transmissions and helps isolate vibration through floors and walls. Even when the cavity between the floor and ceiling is insulated, one of the transmission spots is over the floor joist. Applying Gasket Tape will sever the direct path between the floor and the ceiling. This increases IIC value and provides a quieter, more comfortable environment.

Control Thermal Conductivity: Ghosting lines, or tracking on the interior walls of your home, are unsightly and, more importantly, point to a temperature difference in your wall that can be costing you money. Small particles — from cooking, heating systems, candles and everyday living — float around in our air. At higher temperatures they tend to stay more in motion. But when the particles encounter a colder surface, say, where a 2x4 stud is behind your gypsum drywall, the particles tend to stick and collect. This, over time, leads to lines and unsightly stains on your wall at the studs and ceiling joists. The low thermal conductivity of our Gasket Tape ensures that heat and AC are not lost through the studs, resolving this problem and providing for greater energy efficiency.

Installation Guide


  • The Joist Gasket Tape is 100 linear feet long and available in widths of 1-7/16”, 2-1/4”, and 3”. Select the width appropriate for your joists.
  • Make sure all surfaces are free from dirt, ice, and water before applying the Joist Gasket Tape.


  • Apply the Joist Gasket Tape – adhesive side down – evenly to the top of each joist. This can easily be done by hand.
  • Once placement of the Joist Gasket Tape is complete, apply the sub-floor / drywall as normal to joists.
  • Please note: the use of construction adhesive is NOT recommended when securing the subfloor and will compromise the effectiveness of the Joist Gasket Tape.

Customers Questions and Answers

1) Robert: Hi, is your joist tape product the same as Green Glue ISO tape? Thanks

Trademark Soundproofing Reply: Hi Robert, Yes it is (we both source it from the same place). Thank You.

2) Peter Bogdon: Is this product available in Canada?

Trademark Soundproofing Reply: Hi Peter, We ship to Canada. We do not have a distributor there at this moment.

3) surag: Hello- I need to order a bulk amount of the 3" joint gasket tape. Probably at least 20-25 100' rolls. Are there any discounts for bulk orders? Thanks

Trademark Soundproofing Reply: Please give us a call or email

4) Rey: Joist gasket tape is want to use it on my ceiling my bean is 2/1/2 inch wide how wide should the tape be

Trademark Soundproofing Reply: Hi Rey. Use the 3 inch. Most 2 inch wide joists are 2 and a quarter which would be the exact size of our 2 inch joist gasket tape however if yours is truly 2 and a half inches wide than go with the 3 inch wide tape.

5) Ronn F: How quickly can I receive this product?

Trademark Soundproofing Reply: Ships same day for orders placed by 1 pm ET.

6) Mike: What is the actual width of the 3 inch tape? I have a situation where I am putting in a portion of subfloor over horizontally oriented 2 x 4s and I'm not sure if this will be wide enough. In your installation video it looked like the joists were not completely covered to the edges? recovering all out to the edges and even over the edges a bit? Thank you

Trademark Soundproofing Reply: It is exactly 3 inches wide.

7) Connor N: The joist gasket tape says to "install subfloor normally". Does this include nailing/screwing through the plywood (and tape) into the joists?

Trademark Soundproofing Reply: Yes it does.

8) arne: Is your product available in Canada? Plus, what is the thickness of the joist tape & can it be used on the underneath of joists? We're redoing our basement & I'd like to upgrade my sound system. I'm trying to reduce sound transfer from basement to main floor. Thanks for any info.

Trademark Soundproofing Reply: We ship to Canada. Thickness is 1/8 of an inch.

9) Lynn: Do you have test reports that show the STC improvement when using joint gasket tape on walls?

Trademark Soundproofing Reply: We do not, only for the floors. I can only tell you that we have many large construction companies that use it on all their wall joists claiming that they hear a difference when it is used on the walls too.

10) richard F: I am building a home theater in an unfinished basement. I have ceramic tile on the floor above. Could I used this tape on the underside of the joist before installing the ceiling drywall?

Trademark Soundproofing Reply: Yes you can use it this way. Will help slightly, however it is not proper decoupling.
