Southern41® Thermal System

The Southern41® system is a residential aluminium joinery range that has a thermal break built into the design. In essence the thermal break reduces the thermal transference of cold or heat through the frame. This in turn reduces the energy required to heat or cool a home.

Southern41® differs from other thermally broken products available in New Zealand in that it is made using the 'Pour & Debridge' manufacturing method. This method involves the filling of a channel designed into the extrusion with a resin, then the milling out of the back of the channel to create a 5mm break in the aluminium.

As the go to residential thermal system, Southern41® offers a wide range of window and door product types including:

• Ranch Slider® with Levelstep® upgrade option for a seamless indoors to outdoors transition
• Eurosldier® for the ultimate in water performance and reduced maintenence
• Hinged, French and Bifold doors
• Fixed, awning, casement and sliding windows
