Weathertight Wall and Roofing Systems

Pro Clima supplies advanced roofing underlay membrane systems and wall Weather Resistive Barriers (WRBs) designed to protect NZ buildings’ roofs and walls from wind-driven rain while supporting long-term roof durability. The SOLITEX weathertightness system makes building structures particularly energy-efficient and provides effective protection against damage to structures.

These high-performance functional membranes are extremely open to diffusion, provide maximum watertightness against driving rain, and actively transport moisture to the outside.

For ultimate structure protection, SOLITEX wall barriers and roof underlayment should be combined with humidity-variable airtightness building paper systems on the interior side of the insulation.

Our exterior underlay membranes for roofing and walls are manufactured in Germany and used across projects throughout New Zealand. These WRBs are engineered to deliver reliable weathertightness, vapour management, and installation performance. Builders, architects, and façade engineers rely on Pro Clima roofing underlay and wall membrane solutions to provide dependable protection behind cladding and roofing systems.

High-Performance Roofing Underlay Systems for NZ Conditions

Pro Clima roof underlay and roofing membrane systems are designed to perform in the demanding weather conditions found across New Zealand. Our roofing underlay membranes, roof lining paper, and roofing separation mesh solutions provide a durable secondary weather barrier beneath roof cladding. These roof membranes help manage wind-driven rain, improve windtightness, and support proper moisture control within roof assemblies. With high vapour permeability and robust durability, our roof underlay membranes help create roof systems that stay dry and perform consistently over time.


Wall Underlay and Weather Resistive Barrier Systems

Pro Clima also supplies high-performance exterior wall underlay and wall wrap systems designed to protect wall assemblies from external moisture while supporting effective drying. These Weather Resistive Barriers (WRB) act as a secondary line of defence behind cladding, helping manage wind-driven rain and air movement through the wall. Our underlay membranes are vapour open, allowing moisture within the structure to escape while maintaining a durable and reliable barrier suited to New Zealand’s variable climate conditions.

In real-world applications, a quality exterior underlay plays a key role in maintaining the integrity of the façade. When paired with correct cavity systems and cladding, these membranes help reduce the risk of trapped moisture, improve overall building performance, and support long-term durability. Pro Clima wall systems are designed to integrate with tapes, seals, and connection details, making it easier for builders and façade engineers to achieve consistent weathertightness across the entire building envelope.


Reliable Protection Beneath the Roof Cladding

Roof cladding systems are exposed to significant wind pressure, temperature variation, and moisture throughout their lifespan. A high-quality roof underlay membrane acts as a critical secondary weather barrier beneath the roofing material. Pro Clima roofing underlay systems help prevent water ingress caused by wind-driven rain while allowing trapped moisture vapour within the roof structure to escape. This balance helps protect insulation, framing, and internal linings from moisture accumulation that can lead to long-term structural damage.

For builders and designers across NZ, the practical benefits are clear. Reliable roof underlayment and membrane systems help improve the durability of the roofing assembly while supporting better building performance overall. When used alongside appropriate roof ventilation, separation mesh and netting, these systems contribute to improved drying potential within the roof space. This helps maintain stable internal conditions while reducing moisture risk and extending the lifespan of the roofing system.


Designed for Builders and Roofing Professionals

Pro Clima’s roofing underlay membranes and roofing paper systems are designed with ease of installation in mind. The roof membranes are durable, lightweight, and easy to handle on site, helping NZ builders install a consistent weather barrier across the roof structure. Our roof underlay systems are compatible with a wide range of roofing materials and support both traditional and modern construction methods used throughout New Zealand. Alongside manufacturing and supplying products, Pro Clima also provides technical guidance, training, and on-site support to help teams achieve reliable weathertight roof assemblies.
