At Nova, we manufacture a high-quality range of aluminium secondary glazing systems designed to enhance thermal efficiency, acoustic performance, and security, without altering the appearance of the primary windows. Ideal for heritage buildings, listed properties, and retrofit projects, our secondary glazing is a trusted solution where full window replacement isn’t possible or practical.

Available in a variety of styles including horizontal and vertical sliders, hinged units, fixed panels, and lift-outs, our systems are precision-built for durability, ease of installation, and long-term performance. Slimline aluminium frames ensure a discreet finish, while customisable configurations provide flexibility for both residential and commercial applications. Whether you’re working on conservation work or energy upgrades, Nova’s secondary glazing gives trade professionals a reliable, compliant, and installer-friendly solution.
