Description

Miofol® 170AG is a micro-perforated, water-repellent and permeable aluminium membrane. The back of the membrane has been reinforced with a polypropylene webbing, which has been overlaid with an LDPE coating. The aluminium side is coated with UV-stabilised LDPE, which means the aluminium can resist the negative effects of alkaline. The aluminium surface reflects heat radiation, which helps to ensure higher heat resistance. The unique micro-perforations, and the density of these perforations, ensure the best possible water-resistance in this category, while retaining high permeability.

Applications

Miofol® 170AG is used on the outside of facades (cold side) as water-repellent and permeable layer. Miofol® 170AG can be used behind brick facades as well as closed facade panels. The aluminium layer, in combination with the cavity in the facade, helps to improve insulation. The water-repellent membrane protects the construction and ensures effective insulation and moisture control.

Processing

Miofol® 170AG is micro-perforated and must thus be placed away from hard surfaces. For example, in facades with a soft surface, like mineral wool, the membrane can be placed directly against the soft surface. The reflective side of the membrane must be placed so it faces the cavity; thus the logo facing inwards. This means the logo should NOT be visible from the outside. Maintain a cavity of 20 mm to 40 mm for the best possible heat resistance. Miofol® 170AG must be placed in the same way as roof tiles. Keep an overlap of minimum 150 mm and maximum 200 mm. Use staples to attach Miofol® 170AG to the construction. Use VAST-R® Aluminium tape basic to tape over staples and overlaps. Use VAST-R® Butyl tape and/or Tyvek® FlexWrap tape to make openings and joints wind- and watertight. VAST-R® Butyl tape must be placed under the battens to create an effective water barrier, and to extend the lifespan.
