Blockout Roller Blinds for the Garden Route
Morning light along the coast is beautiful. But at 4:47 am in December, beautiful becomes blinding. In winter, cold air presses through glass all night. A good blockout roller blind gives you the dark when you need it and the warmth when it counts. Year round.
What are blockout roller blinds and why choose them for Garden Route homes?
- Blockout roller blinds use opaque, multi-layered fabric that blocks 100% of light when fully lowered, creating complete darkness in any room.
- They reduce heat transfer through glass by up to 40%, keeping bedrooms cooler in summer and warmer during Garden Route winters.
- Custom Blinds supplies blockout roller blinds from Somfy, Hunter Douglas, and Coulisse, measured and installed across George, Knysna, Plettenberg Bay, and Sedgefield.
- Ideal for bedrooms, nurseries, media rooms, shift workers, and guest suites where controlled darkness improves sleep quality.
- Blockout fabric resists UV degradation, humidity, and salt air — engineered for coastal conditions where standard fabrics fade and weaken faster.
- Available in a wide range of colours and textures from plain white to woven linen-look finishes, so they suit any interior style without looking industrial.
- Motorised options with Somfy or Eve MotionBlinds allow automated schedules — the blind lowers at dusk and rises with your morning alarm.

How Life Feels
Your alarm goes off. Not the sun. You open your eyes in a dark, cool room at the time you chose. No squinting. No pillow over your face. Just rest that actually restored something.
Deep Sleep. Complete darkness triggers melatonin production. You fall asleep faster and stay asleep longer, even through early summer dawns.
Cool in Summer. Blockout fabric reflects heat before it enters the room. The bedroom stays comfortable without running air conditioning all afternoon.
Warm in Winter. The same insulating layer traps warmth inside when temperatures drop. Your heater works less. Your electricity bill shows it.
Quiet Privacy. No one sees in. Street lights stay outside. Headlights from passing cars disappear. The room belongs entirely to you.
“People think blockout blinds are only for bedrooms. I fit them in media rooms, home offices, nurseries — even kitchens where the afternoon glare hits the counter. Once you have had proper darkness when you need it, you notice every room that does not have it.” Duncan, Custom Blinds — 15 years installing across the Garden Route
Why Custom Blinds
Built for Garden Route Conditions
The coast is not kind to cheap window coverings. Salt air corrodes metal. Humidity swells fabric. UV radiation bleaches colours in months. A blockout blind from a franchise chain might look right in the showroom, but the Garden Route tests materials in ways that an inland warehouse cannot predict.
Custom Blinds sources blockout fabrics specifically rated for coastal environments. Every roller mechanism is tested against salt spray exposure. Every bracket is corrosion-resistant. That is not marketing — it is what 8,000+ installations since 2010 have taught us about what works and what does not on this coastline.

What Makes a Roller Blind “Blockout”?
All roller blinds look similar at first glance. A tube, a fabric, a chain or motor. The difference is in the fabric construction. Sheer roller blinds filter light and soften glare, but you can still see shapes through the fabric. Light-filtering blinds sit somewhere in the middle — they diffuse brightness without full transparency.
Blockout fabric is different. It uses multiple bonded layers, typically with a dense inner core that absorbs or reflects light completely. When properly fitted with minimal side gaps, a blockout roller blind creates near-total darkness. Not dimness. Not a vague shadow. Actual darkness at 2 pm on a December afternoon if that is what you need.
The key phrase is “properly fitted.” A poorly measured blockout blind with large side gaps lets light leak around the edges. That is where professional measurement and installation matters more than the fabric itself.
Blockout vs Light-Filtering vs Sheer: Which 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 Garden Route 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 |
| Garden 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, views |
| Coastal Durability | ✓ High — UV + salt resistant | ✓ Good | Moderate — requires care |
Many Garden Route homes use a combination: blockout in the bedrooms and nursery, light-filtering or sheer in living areas where you want brightness without glare. A duo roller system gives you both fabrics on a single bracket — sheer for the day, blockout for the evening — without needing two separate blinds.
Room-by-Room Guide: Where Blockout Makes the Biggest Difference
Bedrooms
This is where most people start, and for good reason. The Garden Route’s early summer sunrises mean light creeps in before 5 am. In winter, the opposite problem — cold air radiates through glass all night. A blockout roller blind addresses both. You sleep in darkness regardless of season, and the insulating layer keeps the room temperature more stable without constant heating or cooling.
For east-facing bedrooms in George and Knysna, where morning sun hits directly, blockout fabric is not a luxury. It is the difference between sleeping until your alarm and waking with the birds.
Nurseries and Children’s Rooms
Babies and toddlers do not understand that 5 am is not morning. Their bodies respond to light. If the room is bright, they are awake. Blockout blinds in a nursery are one of the most practical things a parent can do. Daytime naps become easier. Bedtime becomes consistent. And the room stays cooler in summer, which matters when a small child is sleeping.
Media Rooms and Home Offices
Glare on a screen is more than annoying — it causes eye strain and headaches. A blockout blind in a home office or media room eliminates screen reflections completely. You control the light rather than working around it. For video calls, even lighting matters. Blockout blinds let you use artificial lighting that flatters rather than fighting with uncontrolled window glare.
Guest Suites and Airbnb Properties
Guests notice poor sleep immediately. It shows up in reviews. A well-fitted blockout blind in a rental property bedroom is one of the simplest upgrades with the highest return. Guests sleep well. They leave good reviews. The blind requires almost no maintenance between turnovers — a wipe with a damp cloth is enough.
Shift Workers
Nurses, paramedics, security staff, and hospitality workers across the Garden Route need to sleep during daylight hours. This is not about comfort — it is about health. Sustained poor sleep from daytime light exposure leads to genuine medical problems. A blockout blind creates nighttime conditions at any hour.
“The biggest mistake I see is people choosing a blockout blind and then leaving a 15-millimetre gap on each side. All that light leaks in around the edges. We measure for minimal gap — usually three to five millimetres — and fit side channels where complete darkness is critical. The fabric does its job, but only if the fitting does too.” Duncan, Custom Blinds — 15 years installing across the Garden Route
Fabric Quality: What to Look For
Not all blockout fabrics are equal. Cheap blockout blinds use a single layer of heavily coated polyester that stiffens over time, cracks along fold lines, and discolours in direct sun. Better fabrics use a bonded construction — typically a decorative face, a light-blocking core, and a reflective backing — that stays supple and colour-stable for years.
Custom Blinds sources roller blind fabrics from Somfy, Hunter Douglas, and Coulisse — three of the most respected names in window coverings globally. Each supplier tests fabrics for UV stability, colourfastness, and moisture resistance. That matters on the Garden Route, where a blind faces salt air, humidity, and intense sun exposure that would degrade lesser materials within a season or two.
Colour and Texture Options
Blockout does not mean boring. The current fabric ranges include plain whites, warm ivories, textured linens, woven charcoals, and muted earth tones. The linen-look blockout fabrics are particularly popular in Garden Route homes — they give the visual warmth of natural fabric with the full light-blocking performance of engineered blockout.
Darker colours absorb more heat on the window-facing side but block marginally more light at the edges. Lighter colours with reflective white backing are better for heat rejection. Duncan can advise on which combination suits your specific room orientation and climate exposure.
Cleaning and Maintenance
One of the practical advantages of roller blinds over curtains is maintenance. Blockout roller blinds need almost nothing. A light vacuum with a brush attachment every few months removes dust. For marks or stains, a damp cloth with mild soapy water works. Never use harsh chemicals or abrasive cleaners — they damage the coating.
In coastal homes where salt builds up on surfaces, a wipe-down every three to four weeks keeps the fabric looking fresh. That is the full extent of the care required.
Energy Savings: Not Just a Winter Benefit
The original version of this article focused on winter warmth. That is real — blockout fabric does trap heat inside a room, reducing how hard your heater works during Garden Route winters when overnight temperatures drop below 5°C. But the energy story is bigger than winter.
In summer, when the Garden Route regularly hits 30°C and above, blockout roller blinds reflect solar heat before it enters through the glass. A west-facing bedroom in George or Knysna without window coverings can reach 35°C by mid-afternoon. The same room with blockout blinds lowered during the hottest hours stays noticeably cooler — often enough to avoid running air conditioning entirely.
The insulation works both ways, both seasons. That makes blockout roller blinds one of the few home improvements that pays for itself through reduced energy use, regardless of the time of year.
Motorised Blockout Blinds: Automated Comfort
Manual chain-operated blockout blinds work well. But if you want the blind to lower at sunset and rise with your morning alarm — without touching anything — motorisation changes the experience.
Custom Blinds fits Somfy and Eve MotionBlinds motors into blockout roller blinds. You control them from your phone, set schedules, or integrate with Apple HomeKit, Google Home, or Amazon Alexa. The blind moves silently. No chains for children to reach. No getting out of bed to lower the blind when you realise you forgot.
For homes with multiple windows, motorisation also means you can lower every blockout blind in the house with a single tap. That consistency matters — one bright window in a hallway can undo the darkness in a nearby bedroom.
Motorised blockout blinds with scheduled automation give you complete darkness at bedtime and natural light at wake-up — without lifting a finger.
Installation: Recess, Face-Fix, or No-Drill
How a blockout blind is mounted affects how well it blocks light. There are three main options, and the best choice depends on your window frame and how critical total darkness is.
Recess Mount (Inside the Window Frame)
The blind sits inside the window reveal. This gives a clean, built-in look. The trade-off is a small gap between the fabric edge and the frame sides. For most bedrooms, this gap is acceptable. For nurseries or shift workers who need absolute darkness, side channels can be added to seal the edges.
Face Mount (On the Wall Above the Frame)
The blind is mounted on the wall or ceiling above the window, with the fabric dropping down over the frame. This allows wider coverage — the fabric extends past the window edges, reducing light leakage. It is the better option when the window reveal is shallow or when maximum light blocking matters most.
No-Drill Tension Mount
For renters or heritage properties where drilling is not an option, no-drill blockout roller blinds use a tension bracket system that grips inside the window frame without screws. They are removable, leave no marks, and still provide genuine blockout performance.

Frequently Asked Questions
What is the difference between blockout and blackout blinds?
They are the same thing. “Blockout” and “blackout” both refer to opaque roller blind fabric that blocks 100% of visible light. In South Africa, “blockout” is the more common term. The performance is identical regardless of which word a supplier uses.
Do blockout roller blinds stop light coming in around the edges?
Some light can leak around the sides if the blind is not fitted precisely. Custom Blinds measures for minimal gaps — typically 3-5 mm — and fits side channels where total darkness is critical, such as nurseries or shift worker bedrooms. Proper installation is as important as fabric quality.
Can I get blockout roller blinds in Knysna and the Garden Route?
Yes. Custom Blinds operates across the entire Garden Route, including George, Wilderness, Sedgefield, Knysna, and Plettenberg Bay. Duncan measures on-site at your home and installs the finished blinds. You can also order blockout roller blinds online for self-installation.
Are blockout roller blinds good for nurseries?
They are one of the most practical nursery investments a parent can make. Complete darkness helps babies and toddlers maintain consistent sleep schedules, including daytime naps. Motorised options remove the chain — a child-safe choice that also means you never need to walk into the room and risk waking a sleeping child.
How do you clean blockout roller blinds?
Vacuum lightly with a brush attachment every few months. For marks, use a damp cloth with mild soapy water. In coastal homes, wipe down every three to four weeks to remove salt residue. Never use harsh chemicals or abrasive cleaners, as they damage the blockout coating.
Do blockout blinds help with energy efficiency in South Africa?
Yes, in both directions. In winter, the insulating fabric layer traps warmth inside the room, reducing heating costs. In summer, it reflects solar heat before it enters through the glass. This dual-season benefit makes blockout roller blinds one of the most cost-effective energy-saving home improvements available.
Can blockout roller blinds be motorised?
Yes. Custom Blinds fits Somfy and Eve MotionBlinds motors into blockout roller blinds. Motorised blinds can be controlled via smartphone, voice assistant, or automated schedules. They are chain-free, which is safer for children and more convenient for hard-to-reach windows.
