Meet the Experts: Masons Building Products

Since 1999, Masons has built a strong reputation in New Zealand’s building industry for delivering dependable, high-quality products backed by expert technical support. With a focus on innovation and efficiency, Masons designs systems that help builders work smarter—not harder. From their well-known Flexible Air Barrier systems to Enviro AAC Panel Wall and Floor systems, Masons offers trusted solutions for a wide range of construction needs. 

Stay on Track with UNI PLUS & PRO Flexible Air Barrier Systems 

If you're looking to improve site efficiency and weather protection, Masons' UNI Flexible Air Barrier is a game-changer. This heavy-duty, multi-layer underlay provides up to 90 days (UNI PLUS) or 150 days (UNI PRO) of weather resistance when installed in accordance with its CodeMark certification.

 By allowing interior work to proceed before the cladding is installed, these systems help boost productivity on site. Compared to standard building wraps, UNI PLUS and PRO offer a serious upgrade, delivering increased durability and enhancing long-term cladding performance.

Small Yet Mighty

Masons has introduced a new 60mm-wide 40 Below Platinum Flashing Tape, specifically designed to help reduce construction costs while maintaining airtightness and durability. Ideal for sealing vertical and horizontal seams on UNI PLUS and PRO systems, as well as head flashings, this tape is a small addition with a big impact.

Thanks to its tough aluminium facer, it resists UV exposure for up to 180 days and is perfect for sealing hard-to-reach areas like butterfly seams above windows or small accidental tears in the air barrier. 

Breathe Easy with Masons Passive Roof Ventilation System

Modern homes are more airtight than ever, which is great for keeping warmth in, but not so great when it comes to roof space ventilation. Without proper airflow, moisture can build up in the attic, leading to condensation and eventually mould growth.

Masons addresses this hidden issue with their Passive Roof Ventilation System. Designed for use with long-run metal roofing, this system provides both intake and outlet points to ensure continuous airflow in the roof space.

The result? Regulated temperatures, reduced condensation, and a healthier, drier home environment. 

Whether you're tackling a small residential build or a large-scale development, Masons offers smart, proven systems to help you build better. With decades of industry knowledge and a dedication to quality, Masons is the expert you can trust.
