Black aluminium windows give a house a sharp, modern outline: thin dark frames that make the glass look bigger and tie in with black gutters, gates and light fittings. Coetz™ makes every window in its range in Black powder coat, from small top hung bathroom windows to wide sliding windows. This guide covers where black aluminium windows work best, what they cost compared with White, and what to check before you order.

Why choose black aluminium windows
- A crisp outline. A black frame reads as a thin line, so the window looks lighter and the view looks wider.
- It suits modern finishes. Black works with off-white plaster, grey roofs, face brick, timber cladding and concrete.
- It hides dust. A dark frame shows less of the fine Highveld dust than White does between washes.
- It matches everything else. Black doors, garage doors and gates in the same finish make the whole front look planned.
Where black windows work best
A black frame looks best where it is meant to be seen: a modern farmhouse with white walls, a contemporary home with large glass, or a renovation that wants a clean, updated look. On a traditional cottage with small panes, a softer Bronze or Charcoal can look more at home. See charcoal aluminium windows and bronze aluminium windows for the alternatives.
Black window prices
Black aluminium windows cost about 10% more than White. Bronze and Charcoal cost the same as White. The table shows real shop prices on the 30.5 mm standard frame, excluding VAT, at the time of writing (October 2026).

Across a typical house fitted with eight to ten black aluminium windows, the Black premium usually adds a few thousand rand to the total. Open any product page, choose Black in the colour options and the price updates.
Black windows and heat
On black aluminium windows, the dark frame absorbs more sun than a white one, so it gets warmer to the touch on a north or west wall in summer. The frame is a small part of the window, so the effect on the room is minor next to the glass and the shading. Every Coetz™ window uses 6.38 mm clear laminated safety glass, and good shading such as an overhang does more for a hot room than the frame colour. See window energy efficiency for the bigger picture.
Black frames inside the house
Inside, a black frame works like a picture frame around the view. It suits white walls, pale floors and timber, and it draws the eye outwards. In a room with dark walls, the frame almost disappears, which is a strong look in a study or lounge. Think about curtain tracks and blinds too: black or dark grey fittings keep the look consistent.
Matching black windows to doors
If you want black aluminium windows and doors to match, order them together. Sliding doors, hinged doors and folding doors are all available in the same finish, so the whole elevation lines up. Read our guide to aluminium window colours for how powder coat and anodising differ.
Caring for black windows
Powder coat needs no repainting, and the colour goes right round the profile, so the frame is black inside and out. Wash the frames with mild soap and water a few times a year, rinse with clean water and dry with a soft cloth to avoid water marks, which show more on a dark finish. Avoid abrasive pads and harsh solvents. Full steps are in how to clean aluminium windows.
Before you order black windows
- Measure each opening in three places and use the smallest reading. See how to measure aluminium windows.
- Choose the window type: top hung, side hung, sliding or fixed.
- Select Black on every window and door, so the colour matches across the order.
- Plan delivery: we deliver across South Africa, or you can collect free from our Laser Park workshop.
Coetz™ supplies only, so your builder or installer fits the windows. Glazing must meet SANS 10400-N, published by the South African Bureau of Standards.
Black aluminium windows: frequently asked questions

Do black windows fade?
Powder coat is baked on and holds its colour well. Regular washing keeps the finish looking good for longer.
Are black frames hotter?
The frame warms up more in direct sun, but the frame is a small part of the window, so the effect on the room is minor.

What glass comes in black windows?
6.38 mm clear laminated safety glass, the same as every Coetz™ window.
