SikaMembran® Outdoor plus

SikaMembran® Outdoor plus

Vapor/waterproofing membrane for facades - high vapor permeability

SikaMembran® Outdoor plus is an EPDM sheet membrane with a low vapor diffusion resistance (sd value 3 m) and is thus recommended on the cold side if there is an extremely high vapor pressure on the warm side. The SikaMembran® system is a high-performance vapor control system comprising of various EPDM sheet membranes providing vapor control layers and waterproof barriers for curtain walls. They are suitable for most climatic conditions in combination with the appropriate adhesive.  

  • Highly flexible waterproofing and vapor control system
  • Fast, easy and secure application even in corners
  • Provided with CE-mark according to EN 13984: 2011
  • Meet fire retardant requirements of EN 13501-1 Class E under free suspension
  • No additional mechanical fixing necessary
  • Membrane pre-treatment free
  • Suitable for uneven substrates (blowholes in concrete), leveling of substrate by adhesive
  • Suited to site conditions
  • Durable bond and barrier/seal
  • Ozone- and UV-resistant

Usage

The flexible SikaMembran® Outdoor plus sheets, installed between structure and incorporated units (e.g. facade elements, windows, etc.) using a suitable adhesive, for example SikaBond® TF plus N, provide a secure and durable vapor barrier, as well as a waterproof seal at transitions between building elements, in curtain wall facades, ventilated facades and window installations.
This product is suitable for experienced professional users only.
Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Application

Application Information

Surface preparation

Prior the bonding process ensure that substrates are sound, clean, dry, free from dust, grease, oil and loose particles.

Application

Apply SikaBond® TF plus N adhesive to the corresponding structure or components (nozzle diameter approx. 8 mm).
By using a clean spatula, spread the adhesive bead to approx. 4 - 5 cm width and 1 mm thickness.
Install the SikaMembran® Outdoor plus sheet tension-free and in a way that movement of the connected building parts can be accommodated without damaging the membrane. Press the membrane sheet on the adhesive by a plastic roller. The membrane must be fully bonded over a width of 4 cm. Where overlaps are required ensure at least an overlap of 5 cm.
The membrane might be re-adjusted during a period of 30 minutes after installation.

 

Application limits

SikaMembran® Outdoor plus is not resistant to mineral oils, petroleum, benzene, fuel and toluene etc.
The membrane is not suitable for permanent immersion or standing water.

SikaMembran® Outdoor plus is perforated and thus not resistant to driven rain at wind loads exceeding 0.8 kPa.
