Venetian Blinds in South Africa: Aluminium, Wood and Premium Options Compared
A tilt of the wrist and the whole room changes. Morning light lands where you want it. Glare disappears from your screen. The neighbour’s view stops at the slat. No other blind gives you that level of precise, quiet control over how a room feels.
What are the best venetian blinds in South Africa?
- Aluminium venetian blinds are the most practical choice for bathrooms, kitchens and coastal homes in South Africa — moisture-proof, UV-resistant and available in 25 mm or 50 mm slats.
- Aluwood venetian blinds combine an aluminium core with a timber-look finish, offering the warmth of wood without moisture risk. They suit living rooms and bedrooms across all climates.
- Real wood venetian blinds from suppliers like Hunter Douglas via Blindquip deliver the richest finish and finest engineering, but should be reserved for dry, interior rooms.
- Custom Blinds supplies venetian blinds in aluminium, aluwood, Plaswood, real wood and bamboo — all made to measure and delivered nationwide from the Garden Route.
- As Blindquip’s longest-standing Garden Route agent since 2010, Custom Blinds has direct access to Hunter Douglas and Luxaflex premium venetian ranges not available from general online retailers.
- Coastal homes need aluminium or Plaswood slats with stainless-steel or polymer components. Timber warps in salt-air conditions within two to four years without climate control.

TLDR
Aluminium venetians handle moisture, heat and salt — the go-to for bathrooms, kitchens and the coast. Aluwood gives you the timber look without the risk. Real wood is for dry rooms where finish matters most. Custom Blinds supplies all three tiers, with direct access to Hunter Douglas premium ranges through Blindquip — a supplier relationship that goes back to 2010. Shop venetian blinds online or call Duncan for guidance.
The Venetian Difference
Every other blind is binary — open or closed, light or dark. A venetian blind gives you everything in between. That is why architects still specify them, interior designers still reach for them, and homeowners who fit them rarely go back to anything else.
Directed Light
Tilt slats to bounce light onto the ceiling, across a wall, or away from your desk. You control where it lands.
Graded Privacy
Angled slats block the view in while still letting air and light through. Full privacy without a dark room.
Airflow
Open slats let a breeze move through the room even when the blind is down. Rollers and shutters cannot do this.
Clean Lines
Horizontal slats sit flush in the window frame. No fabric pooling, no swaying, no bulk. Just clean architecture.
“People always ask which blind is best. I ask them what annoys them most about their window right now. If they say glare on one side and no privacy on the other — that is a venetian. Nothing else gives you that kind of directional control.”Duncan, Custom Blinds — 15 years installing across the Garden Route
Venetian Blind Materials: A Quick Overview
Every venetian blind works the same way — horizontal slats on a ladder string, tilted by a wand or cord. The difference is what those slats are made from. That single decision determines where the blind can go, how long it lasts, and what it costs.
In South Africa, five materials cover the full range: aluminium, aluwood, Plaswood (synthetic), real wood and bamboo. Each has a job it does well and conditions it cannot handle. The comparison table below maps material to situation so you can narrow your choice before you measure.
| Feature | Aluminium | Aluwood | Plaswood | Real Wood | Bamboo |
|---|---|---|---|---|---|
| Moisture resistance | Excellent | Very good | Excellent | Poor | Moderate |
| Coastal suitability | Yes | Yes | Yes | No | No |
| Timber appearance | No | Yes — realistic grain | Basic | Yes — genuine | Yes — natural |
| Slat widths | 25 mm / 50 mm | 25 mm / 50 mm | 50 mm | 50 mm | 50 mm |
| Weight | Light | Medium | Medium | Heavy | Light-medium |
| Best for | Bathrooms, kitchens, offices, coast | Living rooms, bedrooms, any climate | Bathrooms, rentals, coast | Dry living rooms, studies | Living rooms, bedrooms (inland) |
| Price tier | Entry | Mid | Entry-mid | Premium | Mid |
Aluminium Venetian Blinds: The Workhorse
Aluminium venetians are the most widely installed venetian blind in South Africa, and for good reason. The slats do not absorb moisture, do not warp in heat, and do not corrode in standard coastal conditions. They wipe clean with a damp cloth. They cost less than any other venetian material.
Available in 25 mm slats for a streamlined look or 50 mm slats for wider windows and a bolder profile. The 25 mm option suits standard residential windows, home offices and compact bathrooms. The 50 mm suits larger openings where narrow slats would look fussy.
Colour range is broad — whites, creams, metallics, charcoals and timber-look finishes. The coating is baked on, not painted, so it resists chipping and fading under South African UV. For kitchens with a cooktop nearby, aluminium handles heat and steam that would damage fabric or wood. For privacy with airflow, no other material at this price point comes close.
Aluwood Venetian Blinds: The Practical Middle Ground
Aluwood solves a common dilemma: you want the warmth of timber but the room gets humid, or the house is on the coast, or the budget does not stretch to real wood. An aluwood slat is aluminium at its core with a PVC timber-grain wrap bonded to the surface. It looks like wood. It feels more substantial than plain aluminium. It handles moisture without flinching.
Available in 25 mm and 50 mm slat widths, with finishes ranging from whitewash and blonde oak through to walnut and mahogany. The grain pattern is printed, but from normal viewing distance the effect is convincing — guests rarely notice the difference until you tell them.
Aluwood is the most versatile venetian option in the Custom Blinds range. It works in every room, every climate, every budget bracket between entry aluminium and premium timber. For bedrooms where you want warmth without worry, or living rooms on the Garden Route coast, aluwood is the recommendation Duncan makes most often.
Real Wood Venetian Blinds: Premium Finish for Dry Rooms
Nothing replicates the weight, grain and warmth of genuine timber slats. Real wood venetian blinds sit in the premium tier for a reason — the material is heavier, the finish is richer, and the engineering tolerances are tighter. When they catch the light, you see actual wood grain rather than a printed pattern.
The trade-off is moisture. Timber expands and contracts with humidity. In a bathroom, a kitchen with regular steam, or a coastal room without climate control, real wood slats will eventually bow, crack or delaminate. This is not a defect. It is the nature of the material. Specify real wood for studies, formal lounges, dry bedrooms and interior rooms where humidity stays below 60 percent.
This is where the Blindquip and Hunter Douglas relationship matters most. Premium timber venetians from Hunter Douglas use kiln-dried hardwood, precision-routed slat profiles and multi-coat lacquer finishes that resist UV yellowing. The ladder strings are engineered to distribute weight evenly so wide blinds hang straight over years of use. These are not details you see on a spec sheet from a general online retailer. They are details you notice after five years of daily use, when the blind still operates smoothly and the finish still looks right.
Which Venetian Blind for Which Room
Bathroom. Aluminium or Plaswood, full stop. Steam, splashing water and high humidity rule out timber and bamboo. Aluminium 25 mm slats in white or silver suit most bathroom windows. Plaswood offers a thicker, woodgrain look if the bathroom has a more designed finish. Both wipe clean and resist mould.
Kitchen. Aluminium handles cooking steam, grease splatter and the temperature swings near a cooktop. The 50 mm aluminium in a metallic or charcoal finish pairs well with modern kitchen joinery. Aluwood works in kitchens that sit further from the stove — an open-plan dining area with a kitchen behind it, for example.
Bedroom. Aluwood or real wood, depending on climate and budget. The wider 50 mm slat creates a calmer, less busy visual than 25 mm. For full blockout, pair a venetian with a roller blind behind it — the venetian handles daytime light control and privacy, the roller handles sleep.
Home office. Venetians are the natural choice for offices because they redirect glare off screens without darkening the room. Aluminium 25 mm in a neutral finish keeps the look professional. Aluwood adds warmth to a dedicated study. Tilt the slats upward to bounce light onto the ceiling — even illumination with no glare on the monitor.
Your Moat
Venetian Blinds for Coastal Homes in South Africa
Salt air is the single biggest factor in blind failure on the South African coast. It penetrates joinery, corrodes steel components, accelerates UV damage and creates the kind of persistent humidity that warps timber. If you live within five kilometres of the ocean — George, Knysna, Plettenberg Bay, Mossel Bay, Sedgefield, anywhere on the Garden Route — your venetian blind specification needs to account for this from day one.
The rules are simple. Aluminium slats with powder-coated finish resist salt corrosion. Stainless-steel or polymer headrail brackets will not rust. Synthetic or aluminium-core ladder strings outlast cotton. Avoid painted steel components, untreated timber and any blind sold without a coastal-specific material note.
Custom Blinds specifies coastal-grade materials as standard for every Garden Route installation. This is not an upgrade or an add-on. It is how we build. After 8,000+ installations since 2010, we have seen what fails at the coast and what lasts. That firsthand knowledge goes into every venetian blind we supply — whether you order online for delivery anywhere in South Africa or book a home consultation with Duncan locally.
Every Custom Blinds venetian for the Garden Route uses coastal-grade components as standard — aluminium or Plaswood slats, polymer brackets, UV-stable coatings. No upgrades needed.
“I have pulled out venetians from a Knysna home that were three years old and the headrail brackets had rusted through. Cheap steel in a salt environment. We stopped using those components in 2012 and have not looked back.”Duncan, Custom Blinds — 8,000+ installations since 2010
The Premium Tier
Hunter Douglas Venetian Blinds via Blindquip
Hunter Douglas is the world’s largest manufacturer of window coverings. Their venetian blinds are engineered to tolerances that mass-market producers do not attempt — precision-profiled slats that close flush without light gaps, spring-return tilt mechanisms that hold position without drift, and lacquer finishes tested to resist UV degradation for a decade of South African sun.
You cannot buy Hunter Douglas direct. Distribution runs through authorised agents, and in South Africa, that means Blindquip. Custom Blinds has been a Blindquip agent since 2010 — the longest-standing partnership on the Garden Route. That relationship gives us direct access to the full Hunter Douglas and Luxaflex venetian range, including premium timber blinds, specialist finishes and wide-span engineering that general online retailers simply cannot source.
Does a Hunter Douglas venetian cost more than an entry-level aluminium? Yes. The difference is in the engineering. A standard aluminium venetian works well for five to eight years. A Hunter Douglas timber or aluminium venetian, properly specified and installed, works well for fifteen. The tilt mechanism stays smooth. The finish does not yellow. The slats do not bow. That is what premium means in practice — not a label, but a measurable difference in how long the blind performs before it needs replacing.
If you are furnishing a high-end home, a guesthouse, a boutique lodge or any property where the finish needs to hold up to scrutiny and daily use, the Hunter Douglas range through Blindquip is where you should start. Visit our Blindquip Knysna or Blindquip George pages for local consultation, or browse the Blindquip range online.

Frequently Asked Questions
What is the difference between aluminium and aluwood venetian blinds?
Aluminium venetian blinds are solid aluminium slats with a baked-on colour finish. Aluwood venetians have an aluminium core wrapped in a PVC timber-grain layer. Aluminium is lighter and cheaper. Aluwood looks like wood but handles moisture and humidity the same way aluminium does. Both are available in 25 mm and 50 mm slat widths.
Are venetian blinds suitable for bathrooms in South Africa?
Yes — provided you choose aluminium or Plaswood. Both materials are fully moisture-resistant and will not warp, swell or grow mould in humid bathroom conditions. Avoid real wood and bamboo venetians in any room with regular steam or water exposure.
Which venetian blinds are best for coastal homes on the Garden Route?
Aluminium, aluwood or Plaswood venetian blinds handle salt air and coastal humidity. Custom Blinds specifies coastal-grade components as standard for all Garden Route installations — polymer brackets, stainless-steel headrails and UV-stable coatings. Real wood should only be used at the coast in fully climate-controlled rooms.
Can I buy Hunter Douglas venetian blinds online in South Africa?
Hunter Douglas products are sold through authorised agents, not direct to the public. Custom Blinds is a Blindquip agent with access to the full Hunter Douglas and Luxaflex venetian range. Contact Duncan on 079 523 5407 for pricing on premium venetian options or visit the Blindquip online page.
How do I clean venetian blinds?
For aluminium and aluwood, wipe each slat with a damp microfibre cloth or run a venetian blind duster between them. For real wood, use a dry cloth only — moisture damages the lacquer. For a full step-by-step guide, read how to clean blinds in South Africa.
What size venetian blind slats should I choose — 25 mm or 50 mm?
The 25 mm slat suits smaller windows, bathrooms and home offices where a streamlined look works best. The 50 mm slat suits larger windows, living rooms and bedrooms where wider slats create a calmer visual. Both sizes provide the same light and privacy control — the choice is aesthetic.
How much do venetian blinds cost in South Africa?
Venetian blind pricing depends on material, size and mechanism. Aluminium is the most affordable, followed by Plaswood and aluwood in the mid range, with real wood and Hunter Douglas products at the premium end. For an exact price, measure your window and enter dimensions on the Custom Blinds online shop — pricing calculates instantly.
Do venetian blinds provide good privacy?
Venetian blinds offer more privacy control than any other blind type. Tilting slats upward blocks the view from outside while still allowing light and air into the room. For a detailed guide on venetian privacy settings, read our venetian blinds privacy guide.
Can Custom Blinds deliver venetian blinds anywhere in South Africa?
Yes. All venetian blinds from the Custom Blinds online shop are made to your measurements and delivered nationwide with tracking. For Garden Route clients in Knysna, George, Plettenberg Bay, Sedgefield and Mossel Bay, Duncan offers on-site measurement and professional installation.
What is Plaswood and is it better than aluminium for venetian blinds?
Plaswood is a synthetic material that mimics the look of painted timber. It handles moisture as well as aluminium and offers a thicker, more substantial slat profile. Plaswood suits bathrooms and coastal homes where you want a wood-like look with complete moisture resistance. Aluminium is lighter and offers a wider colour range. Neither is objectively better — the right choice depends on the look you want and the room conditions.
