A Practical Double Glazing Solution for Apartments and Multilevel Buildings

Many New Zealand apartments and multilevel buildings still have single-glazed windows that let in noise and allow heat to escape. For these properties, replacing entire window units can be costly, disruptive, and often requires scaffolding or external access.

Magnetite provides an innovative solution for double glazing in multilevel buildings or apartments - without the need to replace your existing windows or install scaffolding. Our retrofit system is installed from the inside, making it ideal for hard-to-reach windows and high-rise dwellings.

With over 25 years of experience, Magnetite delivers proven results with up to 70% improvement in insulation and noise reduction. Our team assesses your windows, designs a tailored solution, and installs it with precision - all while keeping the building's exterior untouched.

We work with a trusted network of licensed estimators, fabricators, and installers across Aotearoa, primarily throughout the North Island.
