Product Criteria

Design requirements

Year-round comfort ·        

• In winter, it helps to prevent the coldness coming inside – or the warmth escaping - via your windows and doors. It works the same way in summer, by keeping the air cooler inside. So, whatever the weather is doing outside, you’ll find it easier to set just the right temperature indoors.

H1 Compliance ·        

• Suitable for use in Climate Zones 1,2,3,4,5,6

Reduce condensation

• Even with double-glazing, condensation can still form on joinery and edges of the glass if there’s no thermal break. With Southern41™ Thermal, you’ll have maximum protection against condensation, for a drier and healthier home.

Energy savings ·        

• The R value is the measure of how well a product insulates. By combining your standard clear double glazing with Southern41™ Thermal aluminium framing, you’ll increase your windows R value by 35%. (This increases to 108% if your double-glazing has Low-E and Argon gas).

Larger frames ·        

• Our framing is built to suit larger windows and doors, making it the ideal product for creating superb indoor-outdoor flow.

• Southern41™ Thermal can be used for windows and doors of larger configurations (e.g doors of up to 2.6m).

Stylish square profile ·        

• Southern41™ Thermal framing has a sleek square profile, not rounded, to suit modern architectural aesthetics.

Up to 30mm IGUs ·        

• Our frames can accommodate widths of IGU (Insulated Glazing Unit) up to 30mm.

Maintenance requirements

Instructions on how to use, install and maintain Altus Window Systems joinery are available from Altus or any of its distributors. These instructions must be followed if aluminium joinery is to meet any quality or performance assurance. Regular cleaning is essential if the finish of anodised aluminium is to be preserved over a long period. Cleaning the anodised aluminium should be washed down with warm water and a suitable wetting agent or mild soap solution, in a similar manner to washing a car. View Care and Maintenance Instructions
