Aluwood Venetian Blinds South Africa

Aluwood is the answer to a specific brief. The room wants the warmth of wood, but the room is also humid, coastal, or sees daily moisture. Real wood will fail there. Aluwood is an aluminium venetian blind with a printed wood-grain finish, so the slats handle moisture, UV and salt air the way aluminium does, while the visual reads as timber from normal viewing distance. Custom Blinds Shutters & Awnings supplies aluwood across South Africa with free delivery, instant pricing, and Garden Route installation.

An aluwood venetian blind is an aluminium venetian blind. The slat is aluminium at its core. What makes it aluwood rather than plain aluminium is the surface: a printed wood-grain finish bonded to the metal during manufacture. The finish is sealed, water-resistant, and integrated into the slat rather than painted on top. From a normal viewing distance, the slat reads as timber, with grain pattern, colour variation, and tonal depth. From very close range, the difference is visible. Most buyers do not view their blinds from very close range, which is why the product works as it does.

This matters because aluwood is sometimes described as a wood product or a wood-substitute. It is neither. Aluwood is an aluminium product with a wood look. The material handles moisture, UV intensity, salt air, and temperature variation the way aluminium does, because it is aluminium. The wood characteristics aluwood does not have are the ones that cause real wood to fail in South African coastal and humid conditions: water absorption, fibre swelling, dimensional change with humidity, susceptibility to mould. Aluwood has none of these because the aluminium core has none of these.

The clearest way to think about aluwood: if you would put aluminium venetian blinds in the room and the only thing stopping you is that you want a wood look, aluwood is your answer. It performs like aluminium because it is aluminium. It looks like wood because the finish is wood-grain. The price sits between plain aluminium and real wood, closer to aluminium.

South Africa has the climate conditions that test wood venetian blinds harder than most other markets. High UV intensity bleaches and dries timber. Coastal humidity along the Garden Route, the KwaZulu-Natal coast, and the Cape Peninsula warps and swells wood slats within a few seasons. Inland temperature swings between summer days and winter nights stress the dimensional stability of natural materials. Bathrooms and kitchens generate steam and condensation that real wood cannot handle long-term.

Custom Blinds South Africa works in all of these conditions. We have installed wood venetian blinds in dry Pretoria studies that are operating perfectly fifteen years later. We have removed real wood from Knysna bathrooms that warped within eighteen months. The same product in the wrong room is a different product. Aluwood solves this. The same aesthetic, the same wood-look finish, in a substrate that does not care about the moisture or the salt air.

Custom Blinds Shutters & Awnings order data shows roughly 40 per cent of venetian buyers choose aluwood. It is the single most-ordered venetian material across the national shop. The split makes sense given the climate map: any home with at least one humid or coastal room benefits from aluwood, and most South African homes have at least one of those rooms. See the full venetian material comparison for the framework we use to match material to room.

The three timber-aesthetic venetian materials in the Custom Blinds range each suit different buyers. Aluwood is aluminium with a wood-look finish. Plaswood is a composite of UV-stabilised PVC and wood fibres, engineered by Hunter Douglas specifically for South African climate conditions. Real wood is basswood timber, milled into slats. Each has a job it does well. The choice depends on the room, the budget, and how much the feel of genuine timber matters to the buyer.

Material Comparison

Aluwood vs Plaswood vs Real Wood

Aluwood slats come in a wood-grain finish range that spans the lightest whites through to the darkest stained timbers. The pattern is printed during manufacture, sealed, and bonded to the aluminium substrate. The finish does not chip, peel, or fade under South African UV. Below are the standard finish families Custom Blinds supplies, ordered from lightest to darkest.

Aluwood is the most versatile single venetian in the range because it works in rooms where multiple other materials would also work, and it works in rooms where other materials would not. The room types below cover most South African applications.

Bathrooms. Aluwood handles steam, condensation, and splash exposure without warping or swelling. This is where the product shines compared to real wood, which is the wrong specification for any bathroom. Whitewash and blonde oak finishes pair well with white bathroom suites; walnut suits more dramatic en-suite designs.

Kitchens. Cooktop heat, steam from cooking, and occasional splash near the sink all sit outside the conditions real wood can handle long-term. Aluwood in walnut or mid oak suits warmer kitchen palettes; whitewash works in modern white kitchens. For windows directly above a hob, aluwood handles the heat better than any wood material.

Coastal homes. Salt air within five kilometres of the South African coast is the single biggest factor in blind failure. Aluwood handles it because the substrate is aluminium and the finish is sealed. We have aluwood installations in Knysna, Plettenberg Bay, Mossel Bay, and Sedgefield from 2014 onwards still operating without colour drift or corrosion. Garden Route customers can book a consultation for in-home measurement.

Wide windows and patio doors. Real wood becomes heavy quickly. A 2400mm wide real wood venetian carries enough mass on its headrail that the cord operation becomes stiff and the bracket strain shows over time. Aluwood is lighter than real wood and only slightly heavier than plain aluminium, which makes it the right specification for wide openings where a wood look matters.

Bedrooms in humid regions. Coastal bedrooms, KZN bedrooms, and any bedroom in a home with rising damp benefit from aluwood. The buyer gets the warmth of the wood aesthetic in the sleeping space, and the slats do not respond to the room’s overnight humidity the way real wood would.

Aluwood comes in two standard slat widths. The choice affects the visual proportion of the window, the stack height when fully raised, and the amount of light the closed blind blocks. As a rule of thumb, 25mm slats suit windows under one metre wide and contemporary or office interiors. 50mm slats suit windows over one metre wide and traditional or transitional interiors. The 50mm slat is the more popular choice for residential aluwood because the wider slat exaggerates the wood-grain texture and reads more clearly as timber from the room.

For 50mm slats, decorative ladder tape is available as an upgrade. The tape replaces the plain cord ladder with a woven textile strip running vertically through the slat holes, adding a soft-furnishing detail that works particularly well with aluwood in formal interiors. Hospitality and high-end residential projects often specify ladder-tape aluwood in walnut or mahogany for the depth it adds to a window.

Aluwood venetian blind prices depend on slat width, window size, and any operating mechanism upgrades. The base aluwood specification sits between plain aluminium (entry level) and real wood (premium). The table below indicates relative pricing for a standard 1200mm × 1500mm window.

Aluwood venetian blinds are made to your exact window measurements, so accuracy matters. The full measuring guide covers every scenario in detail. The essential steps follow.

Inside-mount (recess fit): measure the window opening width in three places (top, middle, bottom) and use the smallest width. Measure the drop in two places (left and right) and use the smaller drop. The blind will be manufactured to those exact dimensions and fit inside the recess with minimal clearance.

Outside-mount (face-fit): measure the window opening width and add 50mm to each side for full light coverage. Measure the desired drop from where the blind will start to where it will end. This installation suits windows with irregular recesses or no recess.

Every online aluwood order is protected by the Custom Fit Guarantee. If a measurement error means the blind does not fit on first installation, we remake it. The guarantee applies to all online orders.
