Vertical Blinds. The Practical Solution for Sliding Doors and Wide Windows.
Slide open for full access to the door. Tilt closed for complete privacy. Vertical blinds were designed for the wide openings that horizontal blinds cannot cover, and they remain the most cost-effective way to dress sliding doors, patio doors, and floor-to-ceiling glass across South Africa. Available online with free delivery nationwide, or from our Garden Route showroom with the same expert advice and professional installation.
What are vertical blinds and why are they best for sliding doors?
- Vertical blinds use fabric louvres that hang from a headrail and stack neatly to one side when drawn open, giving full unobstructed access to sliding and patio doors. Louvres rotate 180 degrees for adjustable light and privacy at any angle.
- They are the most cost-effective blind type for wide openings. Where roller or venetian blinds need multiple units across a wide span, vertical blinds cover the full width on a single headrail.
- Custom Blinds® supplies made-to-measure vertical blinds from R750 in blockout fabric. Free delivery to every address in South Africa.
- Custom Fit Guarantee on every order: too big, we trim for free. Too small, 5% off the replacement.
The patio door slides open. The kids run outside. An hour later, you close the blinds with one pull and the lounge is private, cool, and quiet again. No fumbling with a cord. No raising and lowering. Just a smooth lateral slide and a gentle tilt.
“Vertical blinds are still the best solution for sliding doors. Nothing else stacks as neatly, gives full door access, and covers widths over three metres on a single rail. They have evolved well beyond the office look people remember.”

Why are vertical blinds the best choice for sliding doors?
Sliding doors and patio doors are standard in South African homes, from Sandton townhouses to Cape Town apartments to Garden Route beach houses. The opening is typically 1,800mm to 3,600mm wide, sometimes wider. Horizontal blinds (roller, venetian, honeycomb) need to be raised entirely to give access, and most cannot span the full width without multiple units. Vertical blinds solve this because the louvres stack to one side, clearing the doorway completely while the headrail stays in place.
This matters for daily life. You use a sliding door dozens of times a day: letting the dogs out, moving between the kitchen and the braai area, bringing laundry in. A blind that needs to be fully raised each time becomes a chore. A vertical blind draws back in one smooth motion and the door is clear. Over 80% of Custom Blinds® vertical blind installations are on sliding doors and wide patio openings.

What fabric options are available for vertical blinds?
Custom Blinds® supplies vertical blinds in blockout fabric as standard. Blockout vertical louvres provide complete privacy and near-total light block when the slats are closed, making them suitable for bedrooms, media rooms, and any space where darkness and privacy matter.
The fabric is durable, wipe-clean, and fade-resistant under South African UV conditions. Louvres are available in a range of neutral colours that suit both residential and commercial interiors. Each louvre hangs independently from the headrail, meaning individual slats can be replaced if damaged without replacing the entire blind.
Where do vertical blinds work best?
Vertical blinds suit any room with wide openings, but they earn their place most clearly in four situations.
Sliding and patio doors. The primary use case. Louvres stack to one side for unobstructed access, then close and tilt for privacy. No other blind type handles daily sliding door traffic as well.
Floor-to-ceiling windows. In open-plan Gauteng homes and modern Cape Town apartments, floor-to-ceiling glass is common. Vertical blinds cover the full height and width on a single headrail, creating a clean vertical line that complements tall windows rather than fighting them.
Offices and commercial spaces. Vertical blinds remain the standard for South African offices because they cover large glass facades cost-effectively, handle heavy daily use, and allow individual slat replacement. Blockout fabric reduces screen glare during presentations. Over 60% of commercial blind installations nationally use verticals.
Rental properties. Vertical blinds are affordable, durable, and easy to maintain. Landlords choose them for common areas and bedrooms because they withstand tenant turnover better than fabric roller blinds or timber venetians.
How do vertical blinds compare to other blind types for wide windows?
Vertical blinds are not the only option for wide openings, but they remain the most practical and affordable. Here is how they compare to the alternatives.
Roller blinds can be installed in pairs across sliding doors, but each blind operates independently and you need to raise the full panel to access the door. They offer cleaner lines and a wider fabric choice (blockout, translucent, sheer), but lack the lateral stacking that makes verticals practical for daily door use.
Zebra blinds give variable light control with alternating sheer and opaque bands, but they are designed for windows, not doors. They need to be raised for access.
Honeycomb blinds insulate better than any vertical blind, but they also need full raising for access and are more expensive per square metre on wide openings.
Aluminium venetians provide precise light angle control but are impractical on openings wider than about 2,400mm. They need to be raised to access the door.

How do you measure and order vertical blinds online?
Measure the full width of the opening you want covered. For a face fit (mounted above the frame), add at least 100mm on each side and 100mm above the door frame to ensure full coverage. Measure the drop from the headrail position to 10mm above the floor. Record in millimetres.

The fabric is wipe-clean, fade-resistant, and durable under South African UV conditions. Multiple neutral colours are available to suit residential and commercial interiors.
How do I clean vertical blinds?
Dust louvres regularly with a soft cloth or feather duster, wiping from top to bottom. For deeper cleaning, wipe each louvre with a damp cloth. Individual louvres can be unclipped from the headrail for spot cleaning. Avoid submerging fabric louvres in water. For more detail, read how to clean blinds in South Africa.
Can individual vertical blind louvres be replaced?
Yes. Each louvre hangs independently from the headrail, so a single damaged slat can be replaced without removing the entire blind. This makes vertical blinds particularly cost-effective for rental properties and commercial spaces where occasional damage is expected.
Are vertical blinds still in style?
Modern vertical blinds have evolved well beyond the office aesthetic of the 1990s. Contemporary fabric louvres in neutral tones, combined with slim headrails and chainless bottom weights, create a clean, architectural look suited to modern residential interiors. For a softer panel look, consider VertiShades.
