• Suitable for all construction and where there is risk of interstitial condensation
• The protection of insulation from air movement
• Preventing uncontrollable air flow though the building envelope
• An optional continuous cavity for electrical and plumbing services can be created on the inside face of the external wall by fixing battens horizontally over the INTELLO membrane before installing the wall lining
• The main advantage of a service cavity is to shift the plumbing and wiring out of the insulation layer
• A service cavity also reduces the penetrations through the airtightness  membrane allowing easy and fast installation of services
• This also eliminates pressure points on inner lining (eg. plasterboard) from insulation expansion

• Designed for use with fibrous insulation products such as fibre glass, polyester, wool, timber fibre, etc
• Not to be used with vapour tight insulation products such as polystyrene, PIR, EPs, etc

The NZBC requires only that airtightness be considered, not measured. INTELLO directly assists with meeting the following requirements:

• Clause E3.1 INTERNAL MOISTURE: Buildings must safeguard people against illness, injury, or loss of amenity that could result from the accumulation of internal moisture
• Clause E3.2 INTERNAL MOISTURE: Buildings must avoid the likelihood of fungal growth or the accumulation of contaminants on linings and other building elements
• Clause E2 EXTERNAL MOISTURE: Concealed spaces and cavities in buildings must be constructed in a way that prevents external moisture being accumulated or transferred and causing condensation, fungal growth, or degradation of building elements
• Clause E2 EXTERNAL MOISTURE: Building elements must make due allowance for the following: (a) the consequences of failure, (c) variation in the properties of materials and in the characteristics of the site
• Clause E2 EXTERNAL MOISTURE: Interior linings with all joints stopped require barriers to airflow
• Clause H1 : ENERGY EFFICIENCY: The building must be constructed to limit uncontrollable airflow
• Clause H1 : ENERGY EFFICIENCY: Account must be taken of physical conditions likely to affect energy performance of buildings; (c) Airtightness of the building envelope.
• Clause B2 : DURABILITY: Performance B2.3.1(a), not less than 50 years, B2.3.1(b), 15 years and B2.3.2
