Smart Vapour Control Systems for NZ Conditions
Pro Clima airtightness systems use advanced vapour control membrane technology to manage moisture and air movement within the building envelope. Unlike traditional vapour barriers, INTELLO & INTELLO PLUS act as a smart, humidity-variable vapour control layer, adjusting its permeability based on humidity levels. This allows structures to be protected during colder months while enabling drying when conditions change. Designed for NZ construction projects, these systems combine a high-performance air barrier with intelligent vapour control to improve airtightness, reduce condensation risk, and support long-term durability. INTELLO PLUS is not a vapour barrier, but a reinforced, high-performance vapour control layer that supports moisture-safe construction.
Why Standard Vapour Barriers Fall Short in NZ Conditions
Many traditional vapour barrier membranes are static, meaning they perform the same regardless of seasonal conditions. In New Zealand’s mixed climate, this can create performance risks. In winter, moisture from inside the building can migrate into the wall cavity and condense within the structure. In summer, that same moisture can become trapped with limited ability to dry out. In these conditions, a standard wall vapour barrier can contribute to long-term damage, including mould growth and degradation of insulation and framing.
The INTELLO PLUS takes a different approach. As a smart, humidity-variable vapour control layer, it becomes more resistant to moisture diffusion during colder conditions, helping prevent condensation within the structure. When humidity levels increase around the membrane in summer conditions, it becomes more vapour open, allowing moisture to dry toward the interior. For architects and builders across NZ, this means more resilient assemblies, improved moisture safety, and greater confidence in long-term building performance without hidden risks.
Designed for Real Installation and Long-Term Performance
Pro Clima airtightness systems are built to perform on real sites, not just in theory. The membrane is flexible, easy to install, and designed to integrate with tapes, sealants, and connection systems to form a continuous airtight layer. When used as an internal air barrier and vapour control layer in walls and ceilings, it helps ensure consistent performance across the entire building envelope. Backed by robust testing and supported by local technical guidance, the INTELLO PLUS intelligent airtightness system helps ensure an airtight building envelope is achieved successfully.
