Aluminium blinds are rolled metal slats in a tilting headrail, at 16 mm or 25 mm width. They are the material of choice wherever moisture, heat or salt air would destroy timber — kitchens, bathrooms, laundries and every coastal suburb on the Cape Peninsula.

Why Aluminium Rather Than Timber
Aluminium does not swell, warp, rot or grow mould. It shrugs off steam and cooking grease, wipes clean with a damp cloth, and reflects rather than absorbs solar heat. Timber does none of those things. In a bathroom or a west-facing kitchen the material decision is made for you.
| 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: 16mm or 25mm Slats
Most aluminium blinds are aluminium venetian blinds, and 25 mm is the standard slat, suiting almost every window. 16 mm is the narrow option for small openings, shallow reveals and bathroom windows where a 25 mm stack would eat too much glass. The full comparison across every width sits in the slat widths guide.
Coastal Cape Town: Specify the Hardware
The slats are the easy part. What fails first near the sea is the hardware — brackets, tilt rods and chain mechanisms in untreated steel corrode within a few seasons in Bloubergstrand, Table View or Sea Point. We fit rust-resistant fittings as standard on coastal installations, which is the difference between a blind that lasts a decade and one that seizes in three years.
Finishes
- Matt — the default. Hides fingerprints and dust, no glare off the slat face.
- Gloss — brighter and more reflective, better in dark rooms, shows marks sooner.
- Perforated — micro-punched slats that keep some daylight and outward view when closed.
- Wood-effect — printed grain on aluminium, for a timber look in a room timber cannot survive.
Aluminium Blind Prices in Cape Town
Aluminium is generally the most affordable made-to-measure option, typically running well below a timber venetian of the same size. Indicative figures for every type are on the blinds prices page, and a free on-site measure gives you an exact per-window quote.
Aluminium Venetian Blinds Prices by Window Size
Every figure below is the R400–R700 per m² rate on this page applied to that window area, supplied and installed. A minimum order value applies to very small blinds, and a whole-house order works out lower per window — both are confirmed on the quote.
| Window size | Typical room | Area | Supplied & installed |
|---|---|---|---|
| 600 × 900 mm | Bathroom, scullery, passage | 0.54 m² | R220 – R380 |
| 900 × 1200 mm | Small bedroom or study | 1.08 m² | R430 – R760 |
| 1200 × 1500 mm | Standard bedroom or living room | 1.80 m² | R720 – R1,260 |
| 1800 × 2100 mm | Stacking door or picture window | 3.78 m² | R1,510 – R2,650 |
| 2400 × 2100 mm | Wide slider (usually split into two blinds) | 5.04 m² | R2,020 – R3,530 |

Frequently Asked Questions
Are aluminium blinds the same as venetian blinds?
No, not quite. Venetian describes the mechanism — tilting horizontal slats on a cord ladder. Aluminium describes the material. Most aluminium blinds are venetians, but you can also get timber and faux-wood venetians, which is why we treat them as two separate choices. See venetian blinds for the mechanism.
Do aluminium blinds rust near the sea?
No, the slats do not — aluminium does not rust. The risk is the steel hardware, which is why coastal installations get rust-resistant brackets and mechanisms as standard.
Do aluminium blinds bend easily?
Yes, an individual 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.
