Can’t achieve H1 Compliance? Thinking of moving to R4 Cavity Insulation and 140 Framing – STOP !!! Now there is an internationally recognised superior solution: Continuous exterior insulation. ARIDON® SMART WALL eliminates thermal bridging and reduces the likelihood of interstitial condensation by wrapping the frame in a warm, weatherproof shell.
- ARIDON® SMART WALL keeps the timber frame and cavity warm and dry – reducing heat loss and increasing the effective R value of the wall system. Equivalent or superior insulation performance than R4 cavity insulation – and you don’t have to move to 140 framing.
- ARIDON® SMART WALL moves the dew point from inside the framing cavity to the exterior face of the wall, preventing mould and mildew accumulation in the wall.
- ARIDON® SMART WALL – ONE WALL DOES IT ALL: Combines continuous insulation with an in-built drainage plane (cavity battens), self-sealing joints and a rigid air barrier (NZ3604 – exceeding Extra High wind zones), which enables excellent protection against water penetration, reduces material degradation and extends the service life of the building.

Thermal bridging through framing members reduces cavity insulation performance by typically 20% – 30% in timber and steel framing on average. In addition, with modern homes having substantial open areas, there can be significant areas of solid exterior wall with no insulation whatsoever because of the framing requirements.
The ARIDON® SMART WALL System is the only all-in one solution on the market that provides an environmental separator—keeping the outside elements out and the inside temperatures in – enabling a healthier indoor environment, that performs for the life of the building. The ARIDON® SMART WALL system is fully BRANZ appraised and replaces the need for building wrap, rigid air barriers, cavity battens, and insulation. We offer the complete system – fully installed and warrantied by ARIDON Ltd, with a team of structural engineers and draughtsman on hand to answer any technical detailing or structural questions.
How much power does the SMART WALL actually save?
An independent BRANZ energy efficiency study we commissioned identified that in a typical group builder/volume built home the replacement of the ARIDON® SMART WALL system showed “Very good reductions” in space heating requirements. Excellent benefits were seen in the case of the passive solar house examined, with the space heating energy required for comfort provision dropping by over 40% with the 80mm flat panel and nearly 50% with the ARIDON® 80mm Ribbed Panel combined with ARIDON® offcuts installed in the cavities.
