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.
All products within the Southern41™ Thermal range can accommodate double glazed units up to 30mm in width.
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. The result is an increased R-value enabling Southern41™
Thermal to provide maximum protection against condensation making it easier for you to maintain your home at an optimal ‘healthy home’ minimum temperature of 18º Celsius, not to mention the significant energy savings on offer.
The R-value* is a measure of how well a product insulates – the greater the value the greater the insulation properties.
But what is it exactly that makes Southern41™ Thermal different from other thermally broken products available in New Zealand?
As they say, the devil is in the detail. Southern41™ thermally broken joinery is made using the ‘Pour and Debridge’ manufacturing method. This involves filling (the ‘Pour’) a channel designed into the aluminium frame with a resin. The back of the channel is then milled out (the ‘Debridge’) to sever the link between the front and the back of the aluminium and create a 5mm thermal break in the frame.
The resin is incredibly strong so the Southern41™ Thermal System can withstand virtually any climatic conditions, including Extra High wind zones. In fact, Southern41™ Thermal is so strong it exhibits the same performance characteristics of a regular aluminium section. This great strength also makes Southern41™ Thermal suitable for larger windows and doors, with door units up to 2.4m* high for hinged and bifold doors, weighing up to 60kgs and up to 2.6m* high for sliding panels, these weighing up to 220kg, both offer wide glass openings for impressive uninterrupted views and access.
*2.4m high is recommended. Larger sizes may be possible, please contact your local fabricator for advice.
The Southern41™ Thermal System can accommodate almost any combination of window and door configuration, while the framing itself has a sleek square profile, not rounded, to suit modern architectural aesthetics. Innovative products such as the iconic Ranchslider™, functional Levelstep™, and the premium Euroslider™ are all available within the system.
The system is suitable across multiple market segments; Standard Residential-Mid Level Architectural homes, Multi-residential, Light Commercial Applications and A&A (Additions and Alterations)
Ability to use Southern41™ Thermal and other systems on the same build project, whilst
maintaining a consistent appearance and thermal performance.
Wide range of offerings across the residential ranges such as:
Structural integrity allows a product to maintain its original performance throughout its life. This is particularly important in extreme climatic conditions, such as very high or extra high winds.
Shear resistance measures the product’s ability to maintain its composite structure when force is applied. Southern41™ Thermal has three times the shear strength of other thermal products. It also has a high elongation (65%), which reflects structural strength through its ability to bend without breaking.
As this table shows, Southern41™ Thermal has strength implications in its ability to maintain the composite structure.
