External Walls

Exterior solutions that deliver comfort and durability

As New Zealand’s building standards continue to evolve, selecting the right external wall insulation is essential for achieving H1 compliance and creating buildings that are comfortable, durable and fit for purpose.

Our range of external wall insulation solutions are designed for both timber and steel frame construction, helping builders, architects and specifiers meet the thermal performance requirements of the New Zealand Building Code while also improving acoustic comfort. Our external wall insulation helps reduce heat loss through the building envelope and minimise unwanted noise from traffic, neighbours and other urban sound sources.

Manufactured from non-combustible glasswool and silicone-treated for improved moisture resistance, Knauf insulation also supports safer, more durable wall assemblies built for New Zealand conditions. From specification through to installation, our Technical Services team is here to help you select compliant, high-performing insulation solutions for your project.
