Installation Instructions

Spacer Biscuit Method

1. Fix AIR-CELL® loosely to the outside of frame leaving flexibility for AIR-CELL® to be dished onto the wall cavity.
2. Cut AIR-CELL® carefully around doors, windows and other openings, so that it neatly abuts to frames.
3. Butt join AIR-CELL® sheets and tape with a 48mm wide reinforced foil tape.
4. Provide for outer air space by adhering the AIR-CELL® Spacer Biscuits to the outer face of the AIR-CELL® (approximately three (3) Spacer Biscuits per square metre required).
5. Fix outer cladding.

Note: When flat sheet cladding is being installed over AIR-CELL® bubble products, burst the air bubbles with sharp knife or spiked roller so that the cladding can be fixed firmly against the frame.

 

 

 

 

 

 

 

 

 

 

Counter Batten Method

1. Roll out AIR-CELL® horizontally and fix to outside of frame.
2. Cut AIR-CELL® carefully around doors, windows and other openings, so that it neatly abuts to frames.
3. Butt join AIR-CELL® sheets and tape with a 48mm wide reinforced foil tape.
4. Fix counter battens and exterior cladding.

Segmental Method (Timber Frame)

1. Cut AIR-CELL® into panels which are over sized by 50mm to fit between the frame work in each direction.
2. Insert panels at mid depth in the frame and staple to sides, top and bottom of frame.
3. Overlap any joins by 50mm and tape with 48mm reinforced foil tape.

Note: This method will not provide a continuous vapour barrier.

Permishield® Installation Instructions

For use with fibre-cement claddings on steel-framed walls.

1. Fix Permishield® loosely to outside of frame leaving flexibility for it to be dished into the wall cavity.
2. Cut Permishield® carefully around doors, windows and other openings, so that it neatly abuts to frames.
3. Butt join Permishield® sheets and tape with a 48mm wide reinforced foil tape.
4. Provide for outer air space by adhering AIR-CELL® Spacer Biscuits to the outer face of the Permishield®.
5. Commence installing cladding in accordance with manufacturers' installation instructions.
6. Fix cladding by screwing through the Permishield® to the steel frame, and apply even pressure to ensure that the upper board overlap is in full contact with the lower board. If gaps occur, close using brad nails.

Note: Care must be taken that the screw gun torque and depth setting are appropriate to apply even pressure on the Permishield® without over-stressing the cladding material, particularly when installing cladding less than 10mm thick that does not fit flat to the frame. Permishield® 65 should be used when this is the case.

Note: For installations with fibro-cement claddings that are less than 10mm in thickness the Counter Batten method is the preferred method.
