Key Takeaways
- Wooden venetian blinds in South Africa are available in two main materials: basswood (real timber) and aluwood (aluminium with a wood-grain finish).
- Basswood is a lightweight hardwood that offers genuine timber warmth and grain variation; it is moisture-sensitive and best suited to dry interior rooms.
- Aluwood uses an aluminium slat with a printed or laminated wood-grain surface — it handles humidity better and costs less, with a near-identical appearance at normal viewing distance.
- Both are available in 25mm and 50mm slat widths and a range of stained finishes.
- Custom sizing is available for both; made-to-measure is recommended for non-standard windows.
Basswood, Aluwood and Which One Is Right for Your Home
Wooden blinds sit in a different category to aluminium or fabric options — not because they function differently, but because they’re bought differently. The decision to go with timber usually starts with how a room looks and feels, not with a spec sheet. The warm grain, the horizontal lines across a window, the way natural light picks up the texture of the slats — that’s what drives the interest.
What people don’t always know upfront is that “wooden blinds” in the South African market means at least two different products: real basswood and aluwood. They look similar. They behave very differently. And the right choice depends less on aesthetics than on where in your home the blind is going and what the environment is like.
This guide breaks down both materials clearly so you can make the right call before you order.
Basswood Blinds: Real Timber, Real Considerations
Basswood is the timber species used in most real-wood venetian blinds sold in South Africa. It’s a lightweight hardwood — significantly lighter than oak or pine — which makes it practical for window blinds where the weight of the slats affects how smoothly the mechanism operates.
The grain is fine and consistent, which means it takes stain well. Most suppliers offer basswood blinds in a range of finishes from pale natural tones through to darker walnuts and mahoganies, and the result looks like what it is: real wood. There’s a warmth and variation to the grain that no printed finish fully replicates at close range.
Where basswood works
Basswood performs best in stable, dry interior environments. Living rooms, studies, formal dining rooms, main bedrooms — rooms where humidity stays relatively consistent and the blind isn’t exposed to cooking steam, bathroom condensation, or direct moisture.
In Johannesburg’s dry Highveld climate, basswood is well-suited to most rooms in the home. The low ambient humidity means moisture-related warping is less of a risk than in coastal cities, and the timber holds its shape and finish well over time with basic care.
In Cape Town and other coastal environments, the picture is more nuanced. Rooms that are well-sealed and climate-controlled handle basswood without problem. Rooms with poor ventilation, older windows with condensation issues, or any space that sees regular moisture exposure are a different matter. The Western Cape’s winter rainfall and humidity levels can affect timber blinds in rooms that aren’t well-managed.
Where basswood struggles
Kitchens, bathrooms, and laundry rooms are not the right environment for basswood. The moisture cycle — steam, condensation, drying — causes the wood to expand and contract repeatedly, which leads to warping slats and, over time, a blind that no longer hangs straight or operates cleanly.
This isn’t a quality issue — it’s a material issue. Even a well-made basswood blind will deteriorate in a high-humidity room faster than the mechanism wears out. For those rooms, plaswood or aluminium is the right call. The kitchen and bathroom blinds guide covers the alternatives in detail.
Aluwood Blinds: The Practical Argument
Aluwood starts with an aluminium slat — the same base material as a standard venetian blind — and applies a wood-grain finish to the surface. Depending on the manufacturer, this is either a printed film laminate or a painted grain effect. The result, from the distance at which you normally view a blind across a room, is convincingly timber.
The aluminium core changes the performance profile entirely. It doesn’t absorb moisture. It won’t warp in a humid kitchen or a bathroom with poor ventilation. It handles the coastal condensation that causes problems for basswood without any lasting effect. And it’s lighter than timber slats of the same width, which means the operating mechanism tends to stay smoother for longer.
Where aluwood makes sense
For anyone who wants the timber aesthetic but isn’t willing to restrict which rooms they use it in, aluwood is the honest answer. Kitchens with timber cabinetry, bathrooms with a natural design scheme, open-plan spaces that include a kitchen — these are all candidates for aluwood where basswood would be a risk.
It’s also the more budget-conscious option. Aluwood typically costs less than equivalent basswood blinds, which makes a difference when you’re fitting multiple windows across a home.

The honest limitation
Up close, aluwood doesn’t replicate basswood. The grain is printed rather than natural, which means it repeats at regular intervals and lacks the variation of real timber. On a wide slat — 50mm — this is more noticeable than on a 25mm slat. In rooms where you’re regularly at arm’s length from the blind, the difference registers. In most rooms, viewed from a normal distance, it doesn’t.
If authenticity of material matters to you — if you’re specifying natural materials deliberately and the difference between real grain and printed grain is part of the decision — basswood is the right product for the right rooms. If the look is the goal and the environment is mixed, aluwood covers the full house more reliably.
Slat Widths: 25mm vs 50mm
Both basswood and aluwood are available in 25mm and 50mm slat widths, and the same guidance applies to both.
25mm is the standard residential width. Finer, more traditional, better proportioned for most window sizes in South African homes. When the slats are closed, the tighter overlap gives better light control.
50mm is bolder and suits larger windows or interiors where a more graphic, contemporary look is the goal. Fewer slats across the same window height means less visual complexity — which works well in rooms with a strong, clean design language.
As a rule: if the window is under 1,200mm wide, 25mm. If the room is large, the windows are wide, or the interior aesthetic is modern-minimalist, 50mm is worth considering. The aluminium venetian blinds guide covers slat width decisions in more detail if you’re working through this for the first time.
Wooden Blind Finishes in South Africa
The stain range for wooden blinds — both basswood and aluwood — typically runs from light natural and honey tones through mid-range oaks and chestnuts to darker walnuts, mahogany, and near-black finishes.
Light naturals — unbleached honey, natural oak, pale ash — suit interiors with light walls, white cabinetry, or Scandinavian-influenced design. They keep rooms feeling bright and open.
Mid-range stains — golden oak, chestnut, medium walnut — are the most versatile and the most commonly ordered. They work with a broad range of wall colours and furniture finishes without demanding too much from the room around them.
Dark stains — dark walnut, mahogany, dark espresso — suit rooms with deeper colour schemes, darker furniture, or statement interiors where the blind is meant to be noticed. On a 50mm slat, a dark stain creates a strong horizontal graphic across the window.

Wooden Blind Prices in South Africa
Basswood blinds sit above aluminium venetians and below specialist or motorised systems in terms of price. Aluwood is typically priced slightly below equivalent basswood.
The main price drivers are:
- Slat width — 50mm blinds use more material per slat than 25mm, which affects cost on wider windows
- Window size — larger windows require wider, taller blinds with more slats and longer ladder tape
- Stain finish — most standard finishes are priced equally; specialist or darker stains may carry a small premium
- Standard vs custom — made-to-measure is recommended for non-standard windows and adds a modest premium
For Johannesburg and Cape Town buyers fitting multiple windows, getting accurate quotes per window rather than estimating from a single price point is worthwhile — window sizes often vary more across a home than people expect.
FAQ
What is the difference between basswood and aluwood blinds? Basswood is real timber — a lightweight hardwood with natural grain variation. Aluwood is an aluminium slat with a printed wood-grain finish. Basswood looks more authentic up close; aluwood handles moisture better and costs less.
Can wooden blinds be used in a bathroom or kitchen? Basswood is not recommended for bathrooms or kitchens — moisture causes warping over time. Aluwood handles humidity better but is still not ideal for direct steam exposure. Plaswood venetian blinds are the more reliable option for wet rooms.
Are wooden blinds available in custom sizes in South Africa? Yes. Both basswood and aluwood blinds are available made to measure through Blinds Online. Submit your width and drop in millimetres when ordering.
What is aluwood? Aluwood (sometimes written as alu-wood) is an aluminium venetian blind slat with a wood-grain surface finish. It replicates the appearance of timber while retaining the moisture resistance and durability of aluminium.
How do I care for wooden blinds? Dust regularly with a soft cloth or brush. For basswood, avoid damp cleaning — a dry or barely damp cloth is sufficient. Condition the timber annually in very dry environments (air-conditioned rooms particularly) to prevent the slats from drying out and cracking at the edges.
Pick the Right Wood for the Right Room
Basswood and aluwood are both good products. The decision between them isn’t about which is better — it’s about where the blind is going and what the environment demands. Dry, stable room with a natural material brief: basswood. Mixed-use home, humid climate, or rooms where moisture is any part of the picture: aluwood covers the ground without the risk.
