Thermal excellence – because double glazing is only half the story

What is the story with thermally broken windows and doors?

Just as double glazing prevents warmth or coldness from escaping through glass, the thermal break in an aluminium frame does the same for your joinery by stopping any heat transfer via the metal.

Thermal systems can add up to 50% more thermal efficiency to what double glazing alone can provide.

H1 Building code compliance

Clause H1 in the New Zealand Building Code is  designed to ensure new buildings are energy-efficient in terms of their construction and built in such a way that they use less energy for heating, cooling and lighting.

Choosing thermally broken frames is one of the most effective ways to meet H1 requirements and enjoy the peace of mind that comes from knowing you’re creating a warmer, drier, healthier home for your family.

What are the smart options?

Altus® Window Systems is the only provider in New Zealand to offer two thermally broken solutions, each available in a range of window and door styles – these are the Southern41™ Thermal and Pacific52™ Thermal Systems.

Southern41 Thermal 

Southern41 Thermal is a 41mm residential aluminium joinery system with a unique pour’n’debridge thermal break built into the frame to improve the insulation of your home, making it ideal for use in any climate.

Modern and sleek flat-faced frame profiles are available across all frame types. 

Flat-faced frames seamlessly blend with all other Altus Window Systems, where required.

The unique Southern41 thermal break not only builds on the impressive insulating properties of double glazing, it delivers incomparable structural strength whilst combining traditional and modern aesthetic options. 

All to provide you with a warmer, drier, healthier home, all year round.

Pacific52 Thermal

The Pacific52 Thermal System offers next generation thermally broken aluminium joinery designed to deliver improved insulation, noise reduction, strength and the virtual elimination of condensation. 

This is Altus Window Systems' top performer.

Pacific52 Thermal uses a ‘Polyamide Strip’ to extend the benefits of double glazing to the frames of your windows and doors. 

A thermal break within the frame is created by joining two pieces of aluminium together using a 16mm polyamide strip crimped to each side of the frame. 

The thermal barrier formed by the polyamide strip stops the transference of heat from the front of the frame to the back of the frame, thus stopping heat from passing into (or leaving) your house. 

As a result, your home is more comfortable and requires less energy to heat.

Sleek, contemporary lines delineate the Pacific52 Thermal system, while innovative features like the use of flat sill technology add aesthetic practicality, allowing function and form to go hand in hand.
