£21.84 inc. vat (RRP)


Gerband 48/12 Split Release Tape is used indoors, for the airtight bonding and sealing of door and window reveals.

Gerband 48/12 Split Release Tape is an airtight, pliable, stretchable PE-film sealing tape with moisture-resistant polyacrylate adhesive of extremely high tack and permanent adhesion as well as outstanding ageing resistance. The 12mm strip facilitates the speedy and accurate fixing of the tape to window frame. Split release tape permits the installer to quickly apply it to the window frame and reveal in separate and manageable steps.


  • Due to its flexibility in crosswise direction it compensates for any building movements.
  • Provides a permanent air tight and vapour seal.
  • Offers significant savings due to time advantages.
  • Is compatible with acrylic glass, as well as polycarbonates.
  • Provides high adhesion of the sealing strip on all types of window frame.
  • Contains no solvents.

Gerband 88/12 & 48/12 tapes are used indoors for the air-tight bonding and sealing of door and window reveals.

Surfaces must be stable, dry, free of grease and dust, and must not contain adhesive-repellent coatings, some MDF and masonry surface may need a primer coating (such as Primer 6300) for best results.

The installer should firstly apply a sample of the tape and test adhesion.

Fitting Instruction

  • Cut the required length of tape; fold the tape along the split line.
  • The 12mm release liner strip is removed and the tape is applied to the window frame.
  • Removes the remaining liner and fit remaining tape the reveal detail.
  • Ensure there is sufficient stress relief on the tape, this prevent pulling on the tape and possible damage.
