Integra Light Weight Concrete Façade System

Description

The Integra Light Weight Concrete Façade System is a pressure-moderated, cavity-based external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system consists of autoclaved aerated concrete (AAC) panels (Integra panels) fixed over high-density polystyrene or timber battens to form a 20 or 40 mm cavity. The coating system consists of a minimum 5 mm thickness of fibreglass mesh reinforced polymer-modified plasters and high-build, tintable finishing plasters. The plaster is finished with a tintable protective finishing coat. The plaster can be applied to give different texture appearances. 

The system incorporates Resene Construction Systems EdgeSeal joinery flashings. It also incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20 or 40 mm drained cavity.

Scope

The Integra Light Weight Concrete Façade System has been appraised as an external wall cladding system for buildings within the following scope:

  • The scope limitations of NZBC Acceptable Solution E2/AS1 paragraph 1.1.
  • With a risk score of 0-20 calculated in accordance with NZBC Acceptable Solution E2/AS1 Table 2.
  • Situated in NZS 3604 wind zones up to and including extra high.

The Integra Light Weight Concrete Façade System has also been appraised for weathertightness and structural wind loading when used as an external wall cladding system for buildings within the following scope:

  • The scope limitations of NZBC Acceptable Solution E2/AS1 paragraph 1.1.
  • Constructed with timber or steel framing subject to specific engineering design.
  • Situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 2.5 kPa.

The Integra Light Weight Concrete Façade System must only be installed on vertical surfaces (except for tops of parapets, sills and balustrades, which must have a minimum 10° slope and be waterproofed in accordance with the technical literature).

The system is appraised for use with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills. (The Appraisal of the Integra Light Weight Concrete Façade System relies on the joinery meeting the requirements of NZS 4211 for the relevant wind zone or design wind pressure.)
