Installation Instructions
Reflex Insulation™ MD Breather Wall Wrap should be installed in accordance with AS/NZS 4200.2 Pliable Building Membranes and Underlays, Part 2: Installation Requirements.
GENERAL
Reflex Insulation™ MD Breather Wall Wrap should be installed horizontally with the printed side facing outward. Fix the product to all framing members, as a continuous membrane, and ensuring any damage or tears to the membrane are repaired.
Fixings should be galvanised clouts or staples for timber frames, and button head or tek screws for steel frames. In high wind areas, it is recommended to install using flat punched multi-point fasteners or cap screws.
When installing Reflex Insulation™ MD Breather Wall Wrap, line up bottom of the roll covering the base of the timber bottom plate, ensure the product is level.
Horizontal, vertical and end overlaps must be 150 mm, with top layers of the membrane overlapping the outside of the lower layers to prevent water ingress.
Continue until the top of the wall frame is covered, and seal the membrane with tape to the top plate.
At windows or openings, Reflex Insulation™ MD Breather Wall Wrap must be neatly cut, sealed and flashed at all sides to achieve its desired function and facilitate proper drainage to the building flashing. Ensure the membrane diverts water away from the opening.
External cladding should be installed without delay so as not to prolong direct exposure to UV light and other elements.
