Miofol® 170AG
Miofol® 170AG is a micro perforated waterproof breathable aluminium membrane. The back of the membrane is reinforced with a polypropylene fabric over which an LDPE coating is applied. The aluminium side is coated with a UV-stabilized LDPE making the aluminium resistant to alkaline influences. The aluminium surface reflects heat radiation which contributes to higher thermal resistance. The unique microperforation and density of the perforation provide the highest achievable water-repellent of its kind while maintaining high levels of breathability.

Applications
Miofol® 170AG is used in facades as a breathable layer on the outside (cold side). The Miofol® 170AG can be used behind masonry facades as well as behind closed facade cladding. The combination of the aluminium layer with the cavity in the facade increases the insulation value. The waterproofing membrane protects the structure and ensures optimal insulation and moisture management.
Installation
Miofol® 170AG is micro-perforated and should therefore be processed free of hard substrates. In facades with a soft substrate, for example mineral wool, the membrane may be applied directly to the soft substrate. The reflective side of the membrane should be applied toward the cavity. Maintain a cavity of 20 mm to 40 mm for optimal thermal resistance. Apply Miofol® 170AG in a shingle fashion. For overlaps, maintain a minimum of 150 mm and a maximum of 200 mm overlap. Apply Miofol® 170AG to the structure using staples. Tape off staples and overlaps with VASTR® Aluminium tape basic. Seal penetrations and connections wind and watertight with VASTR® Butyl tape and/or Tyvek® FlexWrap tape. For optimal water resistance and durability, VASTR® Butyl tape should be applied under the batten.
