SikaMembran Universal window connection membrane EPDM, 25 m

Description

The SikaMembran Universal in 200 mm covers deeper connection joints without a second strip. The EPDM membrane is highly vapour-tight and is processed with adhesive, not laid on self-adhesively.

Benefits

  • 200 mm width for deeper joints without a second strip
  • EPDM synthetic rubber, resistant to UV, ozone and bitumen
  • Rot-proof and permanently elastic
  • Only 0.6 mm thin, weight per unit area about 0.8 kg/m²
  • Can still be corrected up to 30 minutes after bonding

Areas of application

  • Interior-side connection of the building connection joint
  • Curtain-wall, rear-ventilated facades
  • Sealing between building structure and built-in elements
  • New build and window replacement in existing buildings

Product details

Connection membrane made of synthetic rubber on an EPDM basis, colour black, width 200 mm, thickness 0.6 mm, roll length 25 m, basis weight about 0.8 kg/m². Fire behaviour class E, application temperature 5 to 40 °C, made in Switzerland.

The substrate must be firm, clean, dry and free of dust, grease and oil. It is applied at 5 to 40 °C with a suitable membrane adhesive — the membrane itself is not adhesive. On dry concrete and common building materials no primer is necessary. In the first 30 minutes the sheet can still be shifted; after that it is fixed.

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
    • Alternative Alternative to S730/membrane for the outer layer; choose the tape size according to joint width. Inside, continue with A710 or interior tape – K600 BG1 only seals outside
      €6.09 €0.47 / 1 Metre
    • Alternative Membrane route outside, instead of S730
      €22.95 €0.38 / 1 Metre
    • Only for non-self-adhesive membranes such as SikaMembran Universal/Outdoor
      €12.95 €0.02 / 1 Gram
