The Phonestar SBx Board Sealing Tape is an essential accessory for use with SBx Soundproof Boards, ensuring optimal performance and longevity. Designed specifically to seal the cut edges of SBx boards, this 50m roll of tape prevents silica leakage, which helps to maintain the board's integrity and soundproofing capabilities.

What is the Phonestar SBx Board Sealing Tape?

The Phonestar SBx Board Sealing Tape is a specialised tape that works alongside SBx acoustic boards to secure cut edges and prevent silica leakage. Whenever an SBx board is cut to fit a particular area, the exposed edges should be covered with the sealing tape to ensure no leakage occurs, maintaining the board’s high-density structure and soundproofing properties. This tape provides a simple yet effective way to enhance the lifespan and effectiveness of SBx boards.

How Do You Use the Phonestar SBx Board Sealing Tape?

Using the Phonestar SBx Board Sealing Tape is straightforward:

  1. Measure and Cut: After cutting an SBx board to fit your installation area, measure the length of the exposed edge and cut an appropriate length of tape.
  2. Apply the Tape: Place the tape over the exposed edge, pressing it firmly to ensure a secure fit that completely covers the cut surface.
  3. Ensure Full Coverage: Smooth down the tape to avoid any gaps or air pockets that could allow silica leakage, ensuring a continuous seal along the edge.

The SBx Sealing Tape is provided with orders of SBx boards, making it easy to achieve a sealed, effective soundproofing installation.

Whenever the cut edge of the board is exposed the SBX sealing tape should be used to prevent silica leakage:

Cut the tape to the required length and neatly cover the cut edge of the SBx board
