Logicwall Intertenancy Walls are designed for use in multi-residential buildings such as:

• Apartments
• Terraced housing
• Retirement villages
• Motels
• Hotels

• Logicwall is not a cladding system — requires acrylic render or rainscreen to comply with E2.
• Thermal capabilities do not meet code so additional insulation will be required when the Logicwall is used as exterior walls.

If designed and installed in accordance with AFS technical literature, Logicwall complies with the following provisions of the NZBC:

• B1 Structure - B1.3.1, B1.3.2, B1.3.3 (b, c, f, i, j, m), B1.3.4
• B2 Durability — B2.3.1 (a), B2.3.2 (a, b)
• C3 Fire affecting areas beyond the fire source — C3.4 (a), C3.6
• C6 Structural stability — C6.2
• F2 Hazardous building materials — F2.3.1
• G6 Airborne and impact sound — G6.3.1

B1 — Logicwall is an engineered system, with specifications provided by a certified structural engineer. Please refer to the Logicwall Design Guide for further information including design tables and limitations. There are also test reports available from University of Canterbury and Holmes Solutions outlining Logicwall's compliance with B1.

B2 — Once constructed, Logicwall does not contribute to the structural capacity of the wall which acts as a normal concrete structure. When used and constructed in accordance with the design guide instructions, the Logicwall system complies with B2.

C3 — Once core filled with concrete, Logicwall achieves a fire rating of at least 240/240/180.

C6 — Once core filled with concrete, Logicwall achieves a fire rating of at least 240/240/180.

F2 – Raw materials used in Logicwall are galvanized steel stud, Cemintel fibre cement board and Bostik structural glue. All materials are inert substances.

G6 — Only the 162mm thick panels and above meet or exceed STC 55 acoustic ratings for intertenancy walls. Additional strapping and lining can be used to increase the acoustic ratings on all wall thicknesses.

AFS New Zealand has been manufacturing and installing Logicwall on numerous projects nationwide since 2007. The Logicwall system is owned by CSR in Australia, where they have been manufacturing Logicwall for over 30 years.

AFS New Zealand manufactures Logicwall in Nelson, with offices in Nelson, Auckland, Wellington and Christchurch.

There have been numerous projects throughout the country that have utilised Logicwall as their Intertenancy Walls. Some of these projects include:

• Rose Garden Apartments in Albany, Auckland — Built in 2018, Logicwall Intertenancy Walls were installed on these apartments as also part of the load-bearing structure. This project had 200 apartments over 7 levels and by using Logicwall, the builder was able to speed up the construction programme for this large development.
• Kainga Ora, 25 Banff Ave in Epsom, Auckland — Consisting of 25 units, on a small residential street, Logicwall Intertenancy Walls were able to provide the builder with a solution that reduced disruption to nearby residents and road users. Logicwall intertenancy walls created the vertical structure while also giving the client a durable and low-maintenance system.
• Summerset Regional Buildings — Logicwall Intertenancy Walls have been installed on over 20 projects of Summerset's Retirement Villages. Logicwall is used as the primary vertical structure for their 3-story buildings, providing Summerset with a cost-effective solution for their Regional Main Builds.

Logicwall Intertenancy Walls have been tested by Holmes Solutions to reduce the amount of reinforcing required in the panels. Download the design pathway for structural engineers.

• Acoustic ratings up to STC 69
• Fire ratings up to 240/240/240+
