GENERAL
Trade Select™ Wall Wrap Medium Duty is not designed to withstand prolonged direct exposure to the elements. Accordingly, the outer construction envelope should be installed without delay. Aluminium foil should not come into contact with wet concrete or mortar, as the aluminium is susceptible to alkali corrosion. If installed within 500 metres of the sea, or in a non-residential building where foil surfaces may be exposed to a corrosive atmosphere (including agricultural sheds), foil surfaces should face an enclosed, un-vented air space. To ensure optimum thermal insulation performance, as well as satisfactory durability, a 25 mm air space adjacent to the foil side of the product is recommended.
TIMBER & STEEL FRAMED CONSTRUCTION:
- BRICK VENEER
- REVERSE BRICK VENEER
- LIGHT WEIGHT CLADDING DIRECT TO STUD
- LIGHT WEIGHT CLADDING ON BATTENS
Trade Select™ Wall Wrap Medium Duty should be installed horizontally as a continuous membrane by fixing to all framing members with the blue side facing out. Trade Select™ Wall Wrap Medium Duty should extend from the top plate to the bottom plate on concrete slabs or bearers in timber construction. Fixings are to be no more than 450 mm apart and should be galvanised clouts or staples for fastening to timber construction and use tech screws for fastening to steel constructions. In high wind areas, it is recommended to install using at punched multi-point fasteners or cap screws. Horizontal, vertical and end overlaps must be 150 mm if not taped or 50 mm taped with Ametalin Insulation/Ducting Tape, with all top layers overlapping the outside of lower layers to prevent water ingress. Stagger any vertical overlaps. Any damage made to Trade Select™ Wall Wrap Medium Duty during installation including holes and tears must be repaired. Where Trade Select™ Wall Wrap Medium Duty is intended to act as a vapour barrier, tape and seal all overlapped joins, penetrations and discontinuities with Ametalin Insulation/Ducting Tape to prevent air movement. When Trade Select™ Wall Wrap Medium Duty is installed as a sarking membrane, all penetrations shall be sealed or turned up to facilitate drainage around penetration. Ensure window and door openings are cut neatly and carefully and are properly fitted at ashing points. Trade Select™ Wall Wrap Medium Duty shall be cut back from any hot flue to avoid being a fire hazard. This can be achieved by a clear space of at least 50 mm, or as recommended by the manufacturer of the flue and approved by the local authority.
