Definition
Aluminium windows have frames of powder-coated or anodised aluminium sections, sliding, hinged or tilt-turn. Thermally broken sections separate the outer and inner faces with an insulating strip.
Why it matters on a project
They are a large part of the doors and windows package and affect cooling, dust and noise. Section quality, hardware and installation matter more than looks.
Measurement and pricing
Per square metre or per unit for each size from the door and window schedule, stating section, glazing and hardware.
Common mistake
Installing windows before plaster without protection, or without sealing the gap between frame and wall with foam and silicone, so dust and water get in.
Frequently asked questions
What does a thermally broken section do?
It cuts heat flow through the frame and stops condensation on the inside, lowering the cooling load.
Do windows need shop drawings?
Yes, showing sections, fixing and wall details, approved before fabrication.
