Refurbishment vapour check for sub-and-top installation from the outside

Advantages

  • Best possible reliability thanks to sub-and-top installation
  • Protects building components: humidity-variable sd value allows for installation in spaces between rafters and across rafters
  • Time-saving installation: no adhesion to rafters required
  • No insulation cover necessary
  • Easy to work with: particularly robust thanks to fleece reinforcement
  • Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme

Areas of application

Suitable as a sub-and-top vapour check and airtight membrane for all structures with permeable underlay and sarking membranes (e.g. pro clima SOLITEX) in accordance with DIN 4108-3. The sd value of the underlay membrane on the decking may be a maximum of 0.2 m (g value: 1 MN·s/g ; 16.4 US perms). Also suitable in combination with wood-fibre underlay panels and MDF panels, and with fleece-laminated foam insulation materials (PUR, PIR, EPS etc.) with a thickness of 50 mm (2") and greater.
