Key takeaways
- Faux (PVC or composite) venetian blinds resist moisture and salt air, making them the safest pick for Cape Peninsula bathrooms, kitchens and coastal rooms.
- Aluminium venetian blinds are the lightest and cheapest to buy, but standard finishes can pit within a few kilometres of the surf unless they are anodised or marine grade.
- Real wood venetian blinds look warmest in lounges and studies, yet they warp in humid rooms and sit at the top of the price range.
- The US CPSC links roughly 200 child strangulation deaths since 1991 to window covering cords, so choose cordless or motorised slats in any home with children.
The right venetian blind material depends on the room: pick aluminium for budget-friendly offices and dry spaces, faux PVC for bathrooms, kitchens and coastal windows, and real wood for lounges and studies where warmth matters more than moisture. This guide compares the three venetian blinds materials on looks, durability, weight, maintenance and price so you can order the correct slat the first time.
Each material behaves differently once it faces Cape Peninsula weather, from morning sun on a Sea Point balcony to steam in a Constantia bathroom. Below we work through the wood vs aluminium blinds question, then fold faux into every comparison so the decision is clear by the time you measure your windows.
How Do the Venetian Blinds Materials Look and Feel?
Venetian blinds materials split into three distinct looks: warm natural grain from real wood, crisp slim slats from aluminium, and a timber-effect finish from faux PVC that sits between the two on both appearance and cost. The feel in the hand tells you a lot. Wood is solid and slightly textured, aluminium is cool and thin, and faux is smooth with a moulded grain.
Real wood slats carry a depth of colour that paint and print struggle to copy. Oak, basswood and poplar take stains that suit heritage homes and panelled studies. Aluminium reads modern and minimal, especially in 16mm or 25mm slats, and it comes in a wide colour range including metallics. Faux slats imitate painted timber convincingly from a normal viewing distance, which is why they are popular in rentals and family homes.
If your priority is a high-end, natural statement, wood wins on looks. If you want the thinnest possible profile and a contemporary edge, aluminium is hard to beat. Faux is the pragmatic middle, giving you the timber aesthetic without the premium.
Which Material Survives Humid and Sunny Rooms?
Faux PVC and composite slats survive humid rooms best because they do not absorb water, swell or feed mould, while real wood is the most vulnerable to moisture. In sunny rooms the picture shifts slightly: aluminium reflects heat well, but dark finishes can get hot to the touch and cheaper wood stains may fade over years of direct Cape sun.
Solid timber reacts to moisture in the air. In a bathroom, kitchen or a coastal home catching sea mist, wood slats can warp, cup or discolour over time. That is the core reason faux wood exists. A PVC or composite slat shrugs off steam and spray, so it holds its shape in the rooms that punish timber.
Aluminium brings its own coastal caveat. The metal forms a natural oxide layer that resists everyday corrosion, yet chloride from salt air can cause pitting within a few kilometres of the surf. Near the Atlantic Seaboard or False Bay, specify an anodised or marine-grade finish, or choose faux slats for the most exposed windows. For a deeper look at this trade-off, see our guide to choosing blinds for coastal Cape homes.
Do Weight, Operation and Maintenance Differ Much?
Yes, and the differences matter day to day. Aluminium is the lightest of the three venetian blinds materials, so it tilts and lifts with the least effort, which suits wide office windows. Wood is the heaviest, giving a reassuring feel on smaller windows but a heavier pull on large spans. Faux sits in the middle, closer to wood in weight.
Weight affects more than muscle. Heavy wood blinds on a very wide window can strain cords and brackets, so wider openings sometimes split into two blinds. Aluminium handles width gracefully but can rattle in a breeze and bend if a slat is caught. Faux resists bending better than aluminium and tolerates knocks without denting.
Maintenance follows the material. Aluminium and faux wipe clean with a damp cloth, and faux can even be taken down and rinsed. Real wood needs dry dusting and the occasional wood-safe polish, never a soaking, so the cleaning routine differs across all three finishes.
Cord safety across every material
Operation also means safety. The US Consumer Product Safety Commission links roughly 200 child strangulation deaths to window covering cords since 1991, including incidents involving the inner cords on horizontal blinds (US CPSC, 2006). Whichever material you choose, pick cordless or motorised slats in any home where children live or visit. The material changes the look; the cord mechanism changes the risk.
How Do the Price Ranges Compare?
Aluminium venetian blinds are usually the cheapest to buy, faux wood sits in the middle, and real hardwood occupies the top of the price range. Across wood vs aluminium blinds, the gap widens as the window gets larger, because timber uses more raw material and heavier hardware per metre.
Price is not only the sticker. Factor in lifespan and replacement in the room you are fitting. Cheap aluminium in a coastal bathroom may corrode and need replacing sooner, which erodes the saving. Faux wood in that same room often outlasts both wood and untreated aluminium, so the mid-range price can be the lowest true cost over time.
Installation and sizing also move the number. Very wide windows that need splitting, specialist stains, or motorisation all add to the total. For current local figures and what drives them, our 2026 blinds price guide breaks the costs down by type and size so you can budget before you order.
What Is the Best Material for Each Room?
Match the material to how the room behaves, not just how it looks. Bathrooms, kitchens, laundries and coastal-facing rooms reward faux PVC because moisture is the deciding factor. Lounges, bedrooms, studies and dining rooms suit real wood where warmth and a premium finish carry the space. Offices and high-traffic areas often favour aluminium for its light operation and lower cost.
Here is a simple way to decide:
- Bathroom, kitchen, laundry, coastal window: faux PVC or composite, for full moisture and salt resistance.
- Lounge, bedroom, study, dining room: real wood, for warmth, colour depth and a high-end feel.
- Home office, boardroom, wide windows, rentals: aluminium, for the thinnest profile and the friendliest price.
- Child or pet spaces: any material, but always cordless or motorised slats.
Mixing materials across a home is normal and sensible. Timber in the living areas and faux in the wet rooms gives you the best of both without compromise. If your project spans several room types, Jacobs Blinds and Shutters measures each window and recommends the material room by room, then handles the installation across the Cape Peninsula so the finish is consistent throughout.
Your next step is to measure the windows you are fitting and note which rooms carry moisture, strong sun or young children. With that short list in hand, request a quote from Jacobs Blinds and Shutters and we will match each window to the material that will still look right in ten years.
Frequently asked questions
Which venetian blind material lasts longest in a humid room?
Faux PVC or composite slats last longest in humid rooms because they do not absorb water, swell or grow mould. Aluminium is a close second if the finish is corrosion resistant. Solid wood is the weakest choice for steamy bathrooms and coastal homes.
Are aluminium venetian blinds good for coastal Cape homes?
Aluminium works near the coast only if it is anodised or marine grade. Standard aluminium can pit from salt spray within a few kilometres of the surf, so either specify a protective finish or choose faux slats for the most exposed windows.
Are faux wood venetian blinds cheaper than real wood?
Yes. Faux wood blinds usually cost less than genuine timber slats while mimicking the look. Aluminium is typically the cheapest of the three, and real hardwood sits at the top of the price range.
What is the difference between faux wood and PVC venetian blinds?
Faux wood blinds are made from a PVC or a PVC and wood composite moulded to resemble timber grain. Pure PVC slats are lighter and fully waterproof. Both resist moisture far better than real wood.
