Blockout Roller Blinds South Africa
Full darkness on demand. Made-to-measure blockout roller blinds delivered free across South Africa, from R850. Custom Fit Guarantee on every order.
What are blockout roller blinds and when do you need them?
- Blockout roller blinds use a tightly woven opaque fabric that blocks 99 to 100 percent of incoming light when fully lowered. They are the correct choice for bedrooms, nurseries, media rooms, and any space where complete darkness is required.
- They are distinct from light-filtering blinds (which soften light but do not block it) and sheer or sunscreen blinds (which reduce glare while keeping the room bright). If you need sleep-quality darkness, blockout is the only option.
- Custom Blinds Shutters & Awnings supplies made-to-measure blockout roller blinds from R850, manufactured to your exact window dimensions, with free delivery anywhere in South Africa and a Custom Fit Guarantee.
- For rooms where you also want soft filtered light during the day, consider a duo roller blind instead: one sheer fabric and one blockout on a single bracket, each with its own control.
Garden Route clients: book a free consultation with Duncan. National orders: order online with free delivery.
What makes a roller blind blockout?
The difference between a blockout roller blind and any other roller blind comes down to the fabric construction. Blockout fabrics are either woven from heavy polyester with a PVC or acrylic foam backing, or made entirely from PVC. Both methods fill the gaps in the weave that standard fabrics leave open. Light finds those gaps. Blockout fabrics eliminate them.
When properly measured and fitted, a blockout roller blind reduces incoming light by 99 to 100 percent across the fabric itself. The limiting factor is not the fabric. It is the installation. A blockout blind mounted inside a shallow recess will leave a gap at the sides and bottom where light enters the room around the blind, not through it. For genuine darkness, the blind needs to either cover the full window reveal face-fixed to the wall above the frame, or be installed with side channels that seal the edges. Side channels are available from Custom Blinds as a Hunter Douglas specialist. Contact the team about arranging side channels for your blockout install anywhere in South Africa.
Custom Blinds Shutters & Awnings advises on installation method at the point of ordering. For the Garden Route, Duncan visits and designs the installation around the window. For national orders, the measuring guide covers both recess and face-fix scenarios in detail.
Blockout vs light-filtering vs sheer: which roller blind do you need?
The right choice depends on the room and what bothers you most about the window right now. Here is how the three main roller blind types compare for South African homes.
| Feature | Blockout Roller | Light-Filtering | Sheer Roller |
|---|---|---|---|
| Light blocking | 100%, total darkness | 70–90%, diffused glow | 30–50%, soft natural light |
| Privacy (day) | Complete | Good, silhouettes visible | Partial, shapes visible |
| Privacy (night, lit room) | Complete | Moderate, outlines visible | Poor, clearly visible |
| Heat insulation | High, reflects and traps | Moderate | Minimal |
| UV protection | 100% UV blocked | 80–95% UV blocked | 50–70% UV blocked |
| View preserved | No, opaque when down | Partial, muted view | Yes, soft filtered view |
| Best rooms | Bedrooms, nurseries, media rooms | Living areas, kitchens, offices | Lounge, dining, rooms with views |
| Coastal durability | High, UV + salt resistant | Good | Moderate, requires care |
| Pricing | Get instant price | Get instant price | Get instant price |
Many South African homes use a combination: blockout in bedrooms and nurseries, sheer rollers in living areas where you want brightness with privacy.
Which rooms need blockout roller blinds in South Africa?
South African light is bright and arrives early. In summer, the sun clears the horizon before 6am in most of the country. In coastal areas, the combination of direct sunlight and reflective water means that standard light-filtering fabrics often underperform against expectations. These are the spaces where blockout rollers earn their place.
Bedrooms
The primary use case. Blockout roller blinds are what most South African bedroom windows need: full darkness for quality sleep, clean lines that do not compete with the room, and easy operation morning and evening.
Nurseries
Daytime sleep depends on darkness. A nursery with a light-filtering blind gives a baby a room that dims but does not go dark. A blockout blind gives you an actual nap. Cordless and motorised operation is recommended for child safety.
Media rooms and home offices
Screen glare from uncovered windows is not just uncomfortable, it wastes the room. Blockout roller blinds eliminate reflections on screens and give media rooms the light control that changes how the room feels and functions.
Guest suites and Airbnb properties
Guests expect darkness. Rooms fitted with blockout roller blinds get better reviews, fewer complaints, and more repeat bookings. Low maintenance, durable, and professional-looking.
Kitchens facing west in the afternoon, home offices with afternoon sun on screens, and holiday homes along the coast where early light is particularly strong are all strong candidates. The question is not whether the room would benefit. It is usually which fabric and which installation method.
Blockout roller blinds vs other roller blind types
| Type | Light blocked | Privacy | Best for |
|---|---|---|---|
| Blockout roller | 99 to 100% | Complete | Bedrooms, nurseries, media rooms, shift workers |
| Light-filtering roller | 60 to 85% | Good (day), limited (night) | Living rooms, home offices, kitchens |
| Sheer / sunscreen roller | 5 to 30% | Daytime only | Views with glare reduction, open-plan living areas |
| Duo roller blind | Up to 100% (blockout layer) | Complete when blockout lowered | Bedrooms that need both a sheer daytime option and full blockout |
| Zebra blind | 95 to 99% | Good, not full blockout | Living rooms, offices, bedrooms where some ambient light is acceptable |
Blockout roller blind fabrics from Custom Blinds South Africa
Custom Blinds Shutters & Awnings sources blockout roller blind fabrics from Hunter Douglas and Coulisse, two of the leading blind fabric manufacturers globally. These are not commodity PVC rolls cut from a warehouse. They are engineered fabrics selected for dimensional stability, UV resistance, and long-term colour retention under South African conditions.
The range covers plain weave blockout in neutral and dark tones: whites, creams, greys, charcoals, and black. Most fabrics are available up to 2,700mm wide without a join. Wider windows require a central bracket and a fabric join, which Custom Blinds recommends placing at a vertical mullion where possible to minimise visual impact.
For rooms where appearance matters as much as function, textured blockout fabrics are available in the linen-look and woven ranges. These give a more considered finish than plain PVC-backed fabrics without sacrificing light control.
Blockout roller blind prices in South Africa
Made-to-measure blockout roller blinds from Custom Blinds South Africa start from R850 for a standard small window. The price is driven by width and drop, with fabric selection adding a modest premium for textured or linen-look ranges. All prices include free delivery to any South African address.
The online shop shows live pricing for your exact dimensions. Enter width and drop and the price updates immediately. No quote request forms. No waiting for a callback.
The value comparison worth making is not between CB and the cheapest online option. It is between made-to-measure and stock sizes. A 1,200mm wide stock blind on a 1,100mm wide window leaves a visible gap at the side where light enters the room. A made-to-measure blind at 1,100mm fits the window correctly. For a room where darkness is the point, the fit is the product.
Every order from Custom Blinds South Africa is covered by the Custom Fit Guarantee. Too big, return it for a trim at no cost. Too small, return it for a remake at 5 percent off with the price difference refunded. No other online blind retailer in South Africa offers this.
Motorised blockout roller blinds
A Somfy or MotionBlinds motor fits inside the roller tube, replacing the manual chain with app control, voice commands, or automated schedules. Blockout roller blinds are the most popular blind type to motorise in South Africa, because the combination of full darkness and automated timing directly improves sleep.
Practical benefits beyond convenience: motorised blockout blinds lower at sunset and rise with a morning alarm without any manual effort. For holiday homes or Airbnb properties on the Garden Route or KwaZulu-Natal coast, scheduled movement simulates occupancy while the property sits empty.
Both Somfy and MotionBlinds systems are compatible with Apple Home, Google Home, and Amazon Alexa. Battery-powered motors require no wiring and suit rental properties or rooms without a nearby power point.
Motor selection depends on roller tube diameter, blind weight, and your preferred control method. Duncan advises on the right system for each installation, on-site across the Garden Route or by video call for national orders.
Why do South African conditions demand better blockout blinds?
Most blockout blind guides are written for the UK or Europe, where UV levels are a fraction of what South African homes experience. Standard imported fabrics fade, crack, and lose their blockout properties within two to three years under Highveld or coastal sun.
Custom Blinds sources blockout fabrics from Somfy, Hunter Douglas, and Coulisse, manufacturers whose materials are tested for Southern Hemisphere UV intensity. Every roller mechanism is rated for daily use. Coastal homes on the Garden Route, KZN coast, and Cape coast get additional protection: salt-resistant brackets, corrosion-proof chains, and UV-stabilised fabric that maintains its opacity for a decade or more.
Inland homes face a different challenge. Gauteng, Free State, and Limpopo experience temperature swings of 20°C or more in a single day. Blockout fabric acts as an insulating layer, reflecting heat in summer and trapping warmth in winter. Honeycomb blinds offer even better insulation, but blockout rollers deliver the best combination of darkness and thermal performance at a lower price point.

How to order blockout roller blinds from Custom Blinds South Africa
Measure your window using the measuring guide. Choose your fabric and colour in the online shop. Place the order. Production takes 5 to 7 working days. Free delivery takes 2 to 4 working days after dispatch.
If you are not confident in your measurements, order your best estimate. The Custom Blinds team sends a measuring tape and can arrange a video call to confirm dimensions before production begins. You pay the balance if the confirmed size is larger, or receive a refund if smaller. The blind does not go into production until dimensions are confirmed.

Questions about blockout roller blinds in South Africa
Do blockout roller blinds block 100 percent of light?
Blockout fabric blocks 99 to 100 percent of light through the fabric itself. The actual darkness achieved in a room depends on the installation. A blind mounted inside a shallow recess will leave small gaps at the sides and bottom where light enters around the blind. For genuine full darkness, install the blind face-fixed above the window frame or use side channels to seal the edges.
What is the difference between blockout and blackout blinds?
In South Africa the terms are used interchangeably by most retailers and consumers. Technically, blockout refers to the fabric grade, while blackout can describe the combined performance of fabric plus installation. A correctly installed blockout roller blind from Custom Blinds South Africa gives you a dark room regardless of which term you use.
How much do blockout roller blinds cost in South Africa?
Made-to-measure blockout roller blinds from Custom Blinds South Africa start from R850 for small windows. Standard bedroom windows typically come to R1,100 to R1,600 depending on size and fabric. All prices include free delivery. The online shop at shop.customblinds.co.za shows exact pricing for your dimensions without requiring a quote request.
Are blockout roller blinds suitable for nurseries?
Yes, and they are the recommended choice. Daytime sleep quality in nurseries depends on darkness. A blockout roller blind is the most reliable way to achieve it. Cordless operation or motorisation is strongly recommended for nurseries to eliminate cord hazards for children.
What is the difference between a blockout roller blind and a duo roller blind?
A blockout roller blind is a single fabric on one roller that gives you full darkness when lowered. A duo roller blind mounts two separate fabrics (one sheer, one blockout) on a shared bracket, each with its own control. The duo roller gives you soft filtered light during the day and full blockout at night without needing two separate blinds. Custom Blinds supplies both from the online shop.
Can blockout roller blinds be motorised?
Yes. Every blockout roller blind from Custom Blinds can be motorised with Somfy or MotionBlinds by Coulisse. Somfy integrates with Apple HomeKit, Google Home, Alexa, and Samsung SmartThings. MotionBlinds is battery-powered with no hardwiring required. Motorisation is particularly recommended for nurseries (removes cord hazards) and bedrooms (no need to get out of bed to lower the blind).
Do Custom Blinds deliver blockout roller blinds nationwide?
Yes. Made-to-measure blockout roller blinds ship free to any South African address via the online shop at shop.customblinds.co.za. Production takes 5 to 7 working days. Delivery takes 2 to 4 working days after dispatch. Garden Route clients can book an in-home consultation with Duncan Kane for professional measurement and installation across Knysna, Plettenberg Bay, George, and surrounding areas.
