Sound Lock™ Gasket Seal Tape

Sound Lock Gasket Seal Tape is a self-adhesive neoprene gasket that sticks directly to a door frame. It is 3/16" thick and 3/8" wide, so it fits where a mounted jamb seal will not. It also works on exterior doors and across an existing astragal on a double door.

Use Sound Lock Gasket Seal Tape when there is not enough flat space on the door or frame for the aluminum channel of the Sound Lock Door Jamb Seals. It is also a good choice when you want a lower-profile, simpler seal. Gasket tape has no drop mechanism or hardware to clean, which makes it more practical for exterior doors.

Sound Lock Gasket Seal Tape starts at $99.99 for 25 linear feet, enough for 1 door. The 50 linear foot option is $179.99 and covers 2 doors.

Each roll is 25 ft long and double wide. The 25 linear feet option is half of the roll, split down the middle, and covers 1 door. The 50 linear feet option is the full roll, which is two 25 ft strips, and covers 2 doors.

Yes, Sound Lock Gasket Seal Tape works well on an exterior door. It has no drop mechanism or hardware around the perimeter to collect grime.

Apply Sound Lock Gasket Seal Tape when the temperature is between 50°F and 100°F, in this order:

1. Clean the frame and let it dry. The adhesive needs a clean surface.
2. Cut the tape to length for each side of the frame.
3. Peel back a section of the protective facing and press the tape firmly into place.
4. Keep working along the frame until the hinge side, strike side and top are done.

Yes, Sound Lock Gasket Seal Tape seals only the jambs, so we recommend pairing it with a Sound Lock Door Bottom Seal to seal the bottom of the door. Our Sound Lock Gasket Tape Door Seal Kit includes both.

Yes, apply Sound Lock Gasket Seal Tape directly across the existing astragal. Use two rows side by side for better coverage. The tape is 3/8" wide, so two rows cover about 3/4".

Yes, Sound Lock Gasket Seal Tape is UL fire rated for UL10B.
