Bosig Inside Duo window sealing tape, 75 mm, 2 × 10 m

Description

The Bosig Inside Duo in 75 mm has, in addition to the full-surface butyl layer on the back, a 20 mm wide adhesive strip on the front. This allows the tape to be connected on both sides without additional adhesive.

Benefits

  • 75 mm width for connection joints of shallow depth
  • Full-surface butyl rubber on the back
  • Additional 20 mm adhesive strip on the front
  • Non-woven backing, can be plastered and filled over
  • Two rolls of 10 m each in one pack

Areas of application

  • Room-side sealing of narrow construction joints
  • RAL-compliant window and door installation
  • Connections that are to stick on both sides
  • New build and window replacement in existing buildings

Product details

Window connection tape with non-woven backing, full-surface butyl rubber and 20 mm adhesive strip with paper cover on the front. Colour grey, width 75 mm, roll length 10 m, two rolls per pack.

The substrate must be dry, load-bearing and dust-free. Peel off only half of the split release paper first, align the tape and press it on – this way the position can still be corrected before the butyl finally grips.

For your project

These products go with it

Project: Seal windows and doors to RAL guidelines

Execute the connection joint in three layers: airtight inside (acrylic A710 or interior tape), insulated in the middle (assembly foam or multifunctional tape), driving-rain-tight and vapour-permeable outside (S730 or exterior membrane). Inside must always be tighter than outside.

  1. Prepare the surface

  2. Apply

    • Part of the system Insulates the middle layer; can only be applied with a foam gun
      €11.95 €15.93 / 1 Litre
    • Alternative One tape for all three layers – then without A710 and S730
      €23.29 €2.91 / 1 Metre
    • Alternative One tape for all three layers – then without A710 and S730. Choose the tape dimension according to window installation depth and joint width
      €23.99 €6.00 / 1 Metre
    • Alternative Narrow version (joint 4–30 mm) only for the lower connection – instead of the wide tape, not in addition. Choose the dimension according to the measured joint width
      €13.49 €3.37 / 1 Metre
  3. Seal & join

    • Part of the system Use on the outside (weather side) only
      €10.79 €34.81 / 1 Litre
