Description

Stria™ Cladding Vertical is a cavity-based fibre cement wall cladding. It is designed to be used as an external wall cladding for residential and light commercial type buildings where domestic construction techniques are used.

Scope

1. Stria™ Cladding Vertical installed over 40mm structural cavity battens has been appraised as an external wall cladding for buildings between 0 and 10 m high within the following scope:

• the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
• with a risk score of 0-20, calculated in accordance with NZBC Acceptable Solution E2/AS1, Table 2; and,
• situated in NZS 3604 Wind Zones up to, and including, Extra High.

2. Stria™ Cladding Vertical installed over 20mm timber cavity battens has been appraised for weathertightness and structural wind loading when used as an external vertically fixed wall cladding for buildings between 0 and 25 m high within the following scope:

• buildings with a building height not exceeding 25 m; and,
• constructed with timber framing complying with the NZBC; and,
• situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 3.2 kPa where studs are at maximum 400 mm centres; and,
• with inter-storey deflections designed for and up to height/180 of horizontal in-plane movement during seismic serviceable limit state (SLS) events (based on a 3 m inter-storey height); and,
• constructed with timber framing subject to specific engineering design; and,
• when fixed over James Hardie RAB™ Board rigid air barrier.

3. Stria™Cladding Vertical must only be installed vertically on vertical, flat surfaces.

4. Stria™ Cladding Vertical is appraised for use with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills

(Note: The Appraisal of Stria™Cladding Vertical relies on the joinery meeting the requirements of NZS 4211 for the relevant Wind Zone or design wind pressure.)
