+44 (0)1347 825200 Website

Application

Safe One® A2 is suitable for all vertical wall applications including partially open cladding with joints up to a maximum 50mm and an overall UV exposure of 50%. Safe One® A2 can also be used in roof applications.

Storage & handling:

  • Handle the membrane with care.
  • Ensure that the membrane is not folded or creased.
  • Store the membrane horizontally away from sunlight in a cool, dry sheltered store.
  • Store Glue cartridges upright.

Installation:

  • A continuous, solid supporting structure or framework must be provided for all applications.
  • The supporting structure can be wood, aluminium, steel or concrete.
  • Safe One® A2 achieves a fire rating Euroclass A2-s1,d0 when free hanging or when directly installed on a supporting structure with a flame-retardant classification of A1 or A2.
  • The black coated side faces to the outside.
  • Do not glue the whole membrane surface. Create glue lines /gird lines maximum 600 mm vertical or 600 mm horizontal centres.
  • Patch any damaged areas using membrane cut into a circle shape so that the corners do not peel back. The circular patch should be 25 mm larger than the damaged area.

Overlaps:

  • It is possible to fix the membrane mechanically with staples.
  • Seal overlaps using Stamcoll® Safe Glue Cartridge 310 mls.
  • Vertical laps should be 50 mm minimum.
  • Horizontal laps should be 50 mm minimum. Each cartridge covers approx 8 LM with a 8 mm bead.
  • Stamcoll® Safe Glue Cartridge is tested as a system with Safe One® A2 to EN 13501-1.
  • Store glue in a warm environment. Do not use below 5℃ or over 40℃.

See installation instructions for full details.
