Is there a Grading Standard Used for Aluminium Materials in Windows and Doors?

Blog | June 8th, 2018

Aluminium materials, those used in windows and doors, technically adhere to a set of material rules, which is why some aluminium systems sport premium price tags. We get what we pay for, as they say. First of all, the BCA codes (Building Codes of Australia) covers windows and doors, as documented in the AS2047 specs. Before getting into the red tape, though, isn’t aluminium available in different grades?

Buying in Alloy Variations 

Quite so, this lightweight metal is available in different forms. Each form is equipped with contrasting physical properties. If the wrong alloy is selected for a casement or door frame, then that inferior metal won’t perform as intended. It’ll warp under the sun, corrode in the sea air, and leak like a sieve when the weather turns chilly. Good quality aluminium resists all forms of corrosion, plus it won’t surrender its perfectly extruded shape when warm spells turn to cold snaps.

The Standards Protect Homeowners 

Poorly manufactured, the inferior casement leaks and sends a condensate stream into the window sash. Mould grows and spreads, the walls are cold and damp all the time, and the glass seems to vibrate every time a light breeze brushes up against an outside wall. Aluminium window and door standards guarantee a high-quality build. The casement metal is thicker than average and durable. To put it another way, high-quality products are sold by reputable suppliers, while inferior doors and windows made from cheap aluminium are sold by shady manufacturers. At the end of the day, then, the standards mentioned here exist to protect homeowners. They make sure the best alloys and finest manufacturing procedures are sourced at all times.

All-Weather Aluminium Solutions 

Protective coatings and special pigmented finishes grace top-tier aluminium casements and door framings. They’re dense, solid, loaded with high-quality touches, and built to fit a chosen application. The premium products also employ elegant nesting handles and multipoint locking catches. All in all, the graded standards are performance tested and compliance-certified assets. Windows that adhere to these standards will absolutely perform as intended, so a customer knows quality resides inside their adeptly coated outlines.

Why is this question so important? All around the world, different architectural authorities feel the same way, which just highlights the issue and supports it as an essential structural feature. Well, doors and windows seal interiors and stop exterior conditions from invading. If the vital structural interfaces are framed by an inferior alloy, then they’ll leak and rust. The quality-assured standards covered here act as a grading mechanism, one that determines mechanical and physical resilience.
