Aluminium blinds in Cape Town cost about R400 to R700 per square metre supplied and installed. They are aluminium venetian blinds: rolled metal slats, 16 mm or 25 mm wide, that tilt on a ladder cord. The metal copes with steam and cooking grease better than timber, so it goes into kitchens, bathrooms and laundries. Free measure and quote: call 081 411 8471.
Why aluminium rather than timber
Metal slats do not swell, warp or rot in steam, and a damp cloth lifts grease off them. Basswood takes on moisture and can bow, so real-timber wooden blinds belong in dry living rooms and bedrooms. In a bathroom or a west-facing kitchen, the light, durable metal slat is usually the better choice.
| Aluminium | Real basswood | Faux-wood | |
|---|---|---|---|
| Slat widths | 16 & 25 mm | 50 & 63 mm | 50 & 63 mm |
| Moisture tolerance | Excellent | Poor | Good |
| Weight per m² | Lightest | Light | Heaviest |
| Heat behaviour | Reflects | Absorbs | Absorbs |
| Max practical width | ~2,400 mm | ~2,700 mm | ~2,100 mm |
| Typical life | 10–15 years | 8–12 years | 10–15 years |
Aluminium venetian blinds: 16 mm or 25 mm slats
Most aluminium blinds are aluminium venetian blinds, and 25 mm is the standard slat for an ordinary window. 16 mm is the narrow option for small openings, shallow reveals and bathroom windows, where a 25 mm stack would hide more of the glass when the blind is raised. Every venetian width is compared in the slat widths guide.
Coastal homes: the hardware matters most
Near the sea the slats are rarely what fails. Brackets, tilt rods and chain parts in untreated steel can corrode within a few years in Bloubergstrand, Table View or Sea Point, long before the aluminium wears out. On a coastal window, ask about rust-resistant brackets and mechanisms at the quote.
Finishes
- Matt: hides fingerprints and dust, with no glare off the slat.
- Gloss: brighter, good in a darker room, shows marks sooner.
- Perforated: micro-punched slats that keep some daylight and view when closed.
- Wood-effect: printed grain, for a timber look where timber would not last.

Aluminium, roller or vertical blinds?
An aluminium venetian suits a window you want to tilt for light and air. Roller blinds give a plain fabric face with no slats to dust, and roller blinds cost R450 to R900 per m². Vertical blinds draw to the side on a track, which suits a sliding door better than a venetian. Vertical blinds cost R400 to R750 per m². On a 2.4 m stacking door a vertical is the simpler fit; on a 600 mm bathroom window, a 16 mm aluminium venetian blind is.
Kitchens, bathrooms and offices
See kitchen blinds and bathroom blinds for wet rooms. For office blinds, a 25 mm slat tilted upward cuts screen glare without darkening the room. Window Blinds Cape Town measures, supplies and fits custom aluminium blinds from the Northern Suburbs and the West Coast to the Helderberg and the South Peninsula.
Looking after the slats
Dust the closed slats with a microfibre cloth. Warm water with a drop of dishwashing liquid lifts kitchen grease, and abrasive products dull the coating. More in how to clean blinds.
Frequently asked questions
Are aluminium blinds the same as venetian blinds?
Not quite. Venetian describes the mechanism: horizontal slats that tilt on a ladder cord. Aluminium describes the material, and timber and faux-wood venetians exist too. The mechanism is covered under venetian blinds.
Does aluminium rust near the sea?
Aluminium does not rust the way steel does, though salt air can dull or pit an unprotected surface over time. The weak point is steel hardware: brackets, tilt rods and chain parts. Ask about rust-resistant hardware for a coastal window.
Do the slats bend easily?
A single slat can be bent by force, and that is the material’s one real weakness. A bent slat can usually be replaced on its own without a new blind. See blind repairs.
Can I get custom aluminium sizes?
Yes. Each blind is made to measure to the width and drop of your window, in a matt, gloss, perforated or wood-effect finish.
