Elemental Resistance For Up to Six Months

With a wet and wild first half to 2023, the New Zealand construction industry is hungry for smart and innovative products that help mitigate the weather-induced challenges we constantly face.

The Cemintel Rigid Air Barrier is a 6mm, square edged fibre cement panel ready to disrupt the market with its pressure equalised façade system that forms an effective method of weatherproofing buildings.

Sealed using Ceminseal embedded micro waterblock technology, the Cemintel Rigid Air Barrier protects against wind and rain, allowing work inside the building prior to cladding installation for up to six months from installation.

Pressure equalised systems consist of a cladding or rain screen installed with a ventilated cavity and form an effective method of weatherproofing buildings. For ventilated cavity system installations where wind loads exceed 1.5kPa, Cemintel recommends that a rigid air barrier be used instead of wall wrap.

Cemintel stands for ‘Cement Intelligence’ and is the CSR brand that is responsible for some of the most progressive and innovative cladding materials in Australia and New Zealand. With design and innovation as central drivers, Cemintel is focused on a fresh, intuitive approach to cement-based cladding.

Cemintel responds to the preference for high performance, lightweight materials and the desire for buildings to enhance the environment where we live. These ranges are a reinterpretation of cladding as we know it.

Cemintel Rigid Air Barrier is BRANZ appraised for use as a rigid wall underlay and a temporary weather protecting sheathing on timber and steel framed buildings. It can be made to order; minimum order quantities and lead times apply.

For more information on this and a guide to installation, as well as a list of components and accessories, visit the Cemintel website.

Cemintel is the future of building — and it starts now.

Cemintel Rigid Air Barrier is a 6mm fibre cement panel consisting primarily of Portland Cement, cellulose fibres, sand and water.

Cemintel Rigid Air Barrier is suitable for use in a pressure equalised façade system such as cladding or rainscreen installed with a ventilated cavity as described in E2/AS1.

Cemintel Rigid Air Barrier is suitable for applications subject to relatively higher wind loads and for projects that are left unclad for extended periods that may require resistance to prevent degradation/damage during construction.

Cemintel Rigid Air Barrier is designed for use on timber or steel framed buildings with the following scope:

- Within the scope of NZS3604:2011 Timber framed buildings or NASH Standard Part 2 Light steel framed buildings and within the limitations of Acceptable Solution E2/AS1 External Moisture, Paragraph 1.1 with respect to building size and height.

- Be located 1m or greater from a relevant boundary.

- In any exposure zone (except adverse microclimatic conditions) as defined in NZS3604:2011 (para 4.2.4).

- Wind zones up to and including Extra High.

- Buildings specifically engineered up to and including ULS design wind pressure of 2.5kPa.

Cemintel Rigid Air Barrier and fixings may be exposed to the weather for up to six months before being enclosed with the façade system. Tape used to seal joints or corners of openings should not be exposed to UV for more than 2 months.

Cemintel Rigid Air Barrier may also be incorporated into external wall constructions where the building is located within 1m of the relevant boundary.

Air barriers must be effectively sealed at all perimeters, openings and joints.

Conditions: Cemintel Rigid Air Barrier must be installed in accordance with the Cemintel Rigid Air Barrier Design and Installation Guide.

Clause B1 Structure: Performance Clauses B1.3.1, B1.3.2, B1.3.3 (a, h), B1.3.4
