SEAL THE LAYER.
BEFORE YOU HIDE IT.

Behind plasterboard. Around windows. Across the membrane joints.

01BEHIND THE PLASTERBOARD

  • Insulation
  • Membrane
  • Green sealing tape
  • Plasterboard

Join the membrane before the lining covers the detail.

Illustrative external-wall assembly.

02AROUND THE WINDOW FRAME

  • Window frame
  • Foam inside gap
  • Membrane
  • Sealing tape
Trim fitted
later

Connect frame to compatible membrane before the trim goes on.

Foam fills the gap. The sealing layer connects across it.

03MEMBRANE OVERLAPS

  • Continuous tape
  • Sheet overlap

Connect one sheet to the next.

Centre the tape on the supported sheet overlap.

04CORNERS & LAYER CONNECTIONS

  • Wall membrane
  • Sealing connection

Keep the connection continuous through the corner.

Check the detail before the next layer goes on.

CHECK THE DETAIL BEFORE YOU CLOSE THE WALL.

FAQ

Can it be applied in any weather?

Check application conditions separately from service resistance. Apply to clean, dry, compatible surfaces.

Can it be bonded directly to window foam?

The illustration shows foam inside the gap, not as the tape’s sole bonding surface. Confirm the proposed frame-to-membrane connection, contact surfaces and window system with FasVix before use.

What should I confirm before ordering?

Share the membrane, substrate, joint detail and exposure conditions. Confirm the suitable format and installation requirements for your project.
