Intelligent Airtightness System (INTELLO PLUS)
Description

The pro clima airtightness system prevents uncontrolled air infiltration or leakage through the building envelope, and assists the drying capacity of the building through its unique moisture control properties.

INTELLO PLUS is a high performance vapour check and airtightness membrane that provides optimum protection for all thermal insulation in roofs, walls and floors as well as protecting the internal structure of the building from moisture intrusion.

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 wall lining. The main advantage of a service cavity is to shift the plumbing and wiring out of the insulation layer. It also reduces the penetrations through the airtightness membrane allowing easy and fast installation of services. A service cavity also eliminates pressure points on inner lining (eg. plasterboard) from insulation expansion.

The INTELLO system includes the following components:

  • The INTELLO PLUS Connection Strip is designed to connect the internal airtightness membranes at the junctions between internal and external walls and ceilings.
  • ORCON Liquid Adhesive is a durable airtight sealing glue suitable for bonding all pro clima products to any building material (smooth or rough, masonry or timber).
  • ROFLEX sealing grommets are made of strong and flexible EPDM for rapid and permanent airtight sealing of cable and pipe penetrations through the airtightness layer.
  • TESCON VANA provides a secure and permanent airtight seal of overlaps between INTELLO membranes, joints between membranes and smooth, non-mineral surfaces. It is also suitable for sealing joints between wood-based panels.
  • Use TESCON PROFIL for junctions between windows or doors. Also for junctions between roof underlays, wall and roof membranes and smooth, non-mineral surfaces.

INTELLO PLUS rolls sizes: 1.5m wide and 20m (30sqm) or 50m (75sqm) long and 3.0m (150sqm) wide and 50m long

Key Features
  • Intelligent — an internal airtightness membrane that offers high diffusion tightness in winter and openness in summer, protecting the construction in all climate conditions
  • Protection for thermal insulation
  • Translucent
  • Flexible
  • Easy to install
  • Recyclable
Scope of Use
  • 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.
Limitations on Use

Should not be used in Green Roof construction (eg. construction where there is no back diffusion) without consultation with Pro Clima New Zealand Limited.

Statement of Building Code Compliance

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.
