Airtightness Systems for High-Performance Building Envelopes

Pro Clima airtightness building paper systems are designed to prevent uncontrolled air movement through the building envelope. Our range of building wrap, wall underlay, and house wrap products help builders create reliable airtight layers within modern wall and roof assemblies. Manufactured in Germany and tested to rigorous international standards, these systems support better thermal performance, moisture management, and durability for projects across New Zealand. With nationwide technical support and installer training, we help teams deliver airtight buildings that perform as designed.

Vapour control and airtightness membranes with humidity-variable diffusion resistance provide optimal protection against moisture and subsequent mould growth. When combined with weathertightness membranes on the exterior, they significantly improve the protection of building components and support a healthier, mould-free indoor environment.

High-Performance Building Wrap and Wall Underlay Systems

Pro Clima supplies advanced building wrap and wall underlay systems in NZ designed to improve airtightness across the building envelope. These building underlay products form a critical airtight layer behind linings and within framing systems, helping reduce uncontrolled air leakage. The result is improved insulation performance, greater energy efficiency, and better protection from moisture risks. Designed for modern construction methods in New Zealand, our building paper membranes integrate easily with connection tapes and seals to form a complete airtight system.


Designed for Real World Construction in New Zealand

On site, uncontrolled air leakage can reduce insulation performance, increase heating costs, and introduce moisture into wall systems. Using a high-quality building wrap or wall underlay as part of an airtightness strategy helps prevent these issues. Pro Clima’s airtight building paper solutions are engineered to manage air movement while allowing assemblies to remain vapour open where required. This helps reduce the risk of condensation within framing and improves the long-term durability of the building structure.

For builders and designers across New Zealand, using high-quality building paper means buildings that are easier to heat, more comfortable to live in, and less prone to moisture damage. Our house building underlay systems are designed to integrate with window tapes, penetration seals, and connection membranes to create a continuous airtight layer. Backed by extensive international testing and certification, Pro Clima’s building paper systems provide confidence that the materials installed on site will perform over the lifetime of the building.


Airtightness Systems Built for Builders and Designers

Pro Clima airtightness building paper systems are developed with both design performance and practical installation in mind. Our wide range of building house wrap products is flexible, durable, and easy to work with on site. Architects and façade engineers can confidently specify systems that support high-performance building design, while builders benefit from materials that install cleanly and reliably. Alongside the manufacture and supply of building paper and other wall underlay products, our team provides training, design guidance, and on-site support across NZ to help teams get airtightness details right.
