3. EXECUTION
Conditions
3.1 DELIVERY/STORAGE AND HANDLING
Take delivery of materials and goods and store on site and protect from damage. Store
Stria® Cladding flat on a smooth level surface, keep dry prior to fixing. Protect surfaces,
edges and corners from damage.
Move/handle goods in accordance with manufacturer's requirements; carry panels in a
vertical position to avoid excessive bending.
Reject and replace goods that are damaged or will not provide the required finish.
3.2 PRE-INSTALLATION REQUIREMENTS
Check work previously carried out and confirm it is of the required standard for this part of
the work.
游东湖Moisture content of framing must not exceed the requirements specified by NZS 3602 to
minimize shrinkage and movement after panels are fixed.
3.3 PRE-CLADDING REQUIREMENTS
Check work previously carried out and confirm it is of the required standard for specified
finish. Do not commence work until the substrate is of the standard required by James
3.4 TIMBER FRAMING REQUIREMENTS

蒙古兔complies with NZS 3602. For projects with specific engineering design check compliance
with AS/NZS 1170 and NZS 3603.
Where 600mm spacing of studs apply provide an intermediate means of support for
building underlay and insulation using either 75mm galvanid mesh or polypropylene
tape. Not required where studs spaced at 400mm centres or where rigid air barriers are
provided in place of building underlay.
