What is the thermal glazing story?
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
The efficiency of thermal break systems in window and joinery is evidenced by the fact that their use is now written into building code.
H1 building code compliance in New Zealand ensures new buildings are energy-efficient, comfortable, and minimise power usage by requiring adequate thermal resistance and limited airflow in the building envelope.
What are the smart options?
Altus offers two kinds of thermal break solutions, each available in a range of window and door styles – these are Southern41 Thermal and Pacific52 Thermal.
Southern41™ Thermal
Southern41™ Thermal is a 41mm residential aluminium joinery system with a unique 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 our other systems, where required.
The unique Southern41™ thermal break not only builds on the impressive insulating properties of double glazing, it also delivers incomparable structural strength whilst combining traditional and modern aesthetic options.
All to provide you a comfier, healthier home, all year round.
Pacific52 Thermal
Pacific52 Thermal offers next generation thermally broken aluminium joinery designed to deliver improved insulation, noise reduction, strength and the virtual elimination of condensation.
This is Altus’ 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.
