Gauteng weather and your windows
Almost all of Gauteng’s rain comes in summer afternoon storms, often with hail, and the winters are dry and dusty. Two habits keep any aluminium window working: clear the drainage slots at the bottom of the frame before the storm season, and wash the seals. See aluminium windows leaking and how to clean aluminium windows. Laminated glass helps in hail: if a pane cracks, the interlayer holds it in place.
Ordering in four steps
- Measure each opening; our units are made 10 mm smaller than the catalogue size (see how to measure aluminium windows).
- Choose the type, configuration and colour, and check the drawing, which shows the window as viewed from inside.
- Order online or through the estimator. Windows are made in 1–2 days.
- Collect or receive delivery, and have your builder or installer fit them (see how to install aluminium windows).
Glass and warranty
Every window has 6.38 mm clear laminated safety glass, which meets SANS 10400-N, published by the South African Bureau of Standards. We don’t supply tinted or double-glazed aluminium windows. Frames, glass and powder coating are covered for 5 years and hardware and seals for 2 years against manufacturing defects (see our warranty).

Ordering Aluminium windows Gauteng: a five-point checklist
Most delays on aluminium windows Gauteng orders come from one of five details. Check them before you order:
- Size: measure each opening at three points across and three points down, use the smallest figure and choose the next standard size below it.
- Style per room: top hung windows stay open in light rain, side hung windows give the most airflow, and sliding windows suit openings where a sash must not project.
- Bathrooms: on aluminium windows Gauteng orders, add obscure glass to bathroom windows in the online estimator at R248 per m².
- Opening side: every product drawing is shown from inside, so check which sash opens before you order.
- Colour: White, Bronze and Charcoal cost the same; Black is about 10% more and Natural Anodised about 20% more.
Once those are settled, aluminium windows Gauteng orders are made in 1–2 days at our Laser Park workshop, then delivered from R650 excluding VAT in the Johannesburg zone or R950 elsewhere in Gauteng (checkout works it out from your postcode), or collected free. Coetz™ supplies only, so book your builder or installer for the delivery week.
