Managing moisture effectively in high humidity environments, such as bathrooms, is crucial for maintaining structural integrity, indoor air quality, and energy efficiency. Pro Clima’s INTELLO vapour control membrane is an innovative product designed to tackle these challenges, by controlling moisture and air infiltration within the building envelope. INTELLO is BRANZ Appraised and assists in compliance with NZBC Clauses B2, E3, F2 and H1.

The challenge of high humidity environments

Bathrooms are among the most moisture-laden spaces in a building, with frequent exposure to water and steam. Poor moisture management can lead to condensation within the thermal envelope, mould growth, and damage to building materials. This compromises the structural integrity of the building and poses health risks to occupants. Traditional vapour barriers lack the adaptive qualities needed to handle fluctuating humidity levels effectively, leading to moisture being trapped, causing more damage than if they weren’t used.

Why is Intello so effective in managing airflow and moisture buildup?

Pro Clima INTELLO is a smart vapour control membrane that adapts to changing environmental conditions. It features a humidity variable diffusion resistance, meaning its permeability adjusts based on the humidity of the surrounding environment.

During cooler less humid winter months, INTELLO acts as a vapour barrier, preventing moisture from penetrating the building envelope from the interior. And in hot, humid summer months, when moisture is being driven through the envelope from outside, the membrane becomes more vapour permeable, allowing trapped moisture to escape and be removed through ventilation. This dynamic functionality reduces the risk of condensation and ensures that building materials remain dry and functional over time.

Key benefits of INTELLO in bathrooms

1. Dynamic moisture management
   INTELLO’s ability to adapt permeability ensures optimal moisture control, even in high-humidity environments.
   
   
2. Improved durability
   The membrane protects underlying structural components, such as timber and insulation, from prolonged exposure to moisture.
   
   
3. Enhanced indoor air quality
   By preventing mould and mildew growth, INTELLO contributes to a cleaner, healthier environment, which is particularly important in spaces like bathrooms where moisture issues are prevalent.
   
   
4. Energy efficiency
   Effective airtightness and moisture control contribute to improved thermal performance. By reducing unwanted air infiltration, INTELLO improves the effectiveness of bathroom ventilation, heating and cooling.

INTELLO is installed with other Pro Clima products such as VANA tape, ORCON sealant and ROFLEX penetration seals, to create an airtight and moisture-controlled protective layer. By incorporating INTELLO into bathroom construction or renovation projects alongside insulation and mechanical ventilation, builders and designers can ensure long-lasting performance, sustainability, and occupant comfort, addressing moisture management challenges with confidence and ease.
