The standard 52mm system supports triple glazing, while the 60mm fixed window system takes performance even further, allowing for larger, higher-performing glazing options.

Designed for versatility, Pacific52™ Thermal seamlessly adapts to a range of projects – from mid-level residential and high-end architectural homes to multi-residential developments, light commercial applications, school builds, exposed architectural designs, and renovations (A&A).

Whatever the setting, Pacific52™ Thermal delivers exceptional performance and design flexibility.

Thermal Break – what is it?

A thermal break prevents heat transfer between the interior and exterior sections of the frame providing enhanced insulation and energy efficiency. The Pacific52™ Thermal system achieves this using polyamide strip technology, where a 16mm polyamide strip is crimped between two aluminium sections, effectively separating the internal and external aluminium. This thermal barrier reduces heat loss, minimizes condensation, and improves comfort levels – all while maintaining the strength and durability of the aluminium.

With Pacific52™ Thermal, you get the best of both worlds: the sleek, architectural appeal of aluminium with cutting-edge thermal performance designed for high-end homes and challenging climates.
