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.
