Custom Blinds Shutters & Awnings supplies made-to-measure vertical blockout blinds nationally, with free delivery across South Africa and professional installation on the Garden Route.
Why vertical blinds for sliding doors
Vertical blinds are the only blind type that clears the full width of a sliding door or stacker door when open. Unlike roller blinds, the louvres stack to one side and do not obstruct the doorway. For openings wider than 2400mm, vertical blinds are usually the most practical solution. The blockout fabric option provides complete room darkening for bedrooms and media rooms.

Vertical Blinds -- Made to Measure in South Africa
Custom Blinds vertical blinds are made-to-order window coverings designed for wide openings, sliding doors, and large windows. Each blind is custom manufactured in South Africa to your exact measurements, with a typical production time of approximately 5 working days and free nationwide delivery. Vertical blinds use individual fabric vanes that hang from a top track and glide smoothly from side to side.
Who Vertical Blinds Are For
Vertical blinds are the practical choice for sliding doors, stacker doors, wide picture windows, and any opening that is wider than it is tall. They suit living rooms with large glass doors leading to patios or gardens, offices with floor-to-ceiling windows, and commercial spaces. Families appreciate their durability -- each vane moves independently with a weighted bottom that keeps it stable. Unlike older vertical blinds, modern vanes are unlinked, so they hang and move independently without tangling.
How They Work
Vertical blinds consist of individual fabric vanes suspended from a headrail track. The vanes rotate via a control wand to adjust light and privacy. A cord or wand draws the vanes across the track -- available in left-draw, right-draw, or split-draw (opening from the centre). The blockout fabric prevents light from passing through the vanes themselves. Each vane has a weighted bottom that keeps it hanging straight, even with doors open and air movement.
What Makes Custom Blinds Different
Custom Blinds has completed over 8,000 installations since 2010, operating from Knysna on the Garden Route. Every online order goes through an expert verification step -- the Custom Blinds team checks your measurements and specifications before production begins, reducing the risk of costly errors. The Custom Fit Guarantee protects every order: if your blind arrives too large, Custom Blinds will trim it free of charge. If it arrives too small, you receive 5% off a replacement blind.
Pricing and Ordering

No waiting for email quotes or callbacks. All orders include free delivery anywhere in South Africa.
Fabric and Colour Range
The vertical blind fabric range includes blockout options in neutral tones like white, ivory, grey, and beige, as well as bolder colour choices. The blockout fabric provides complete light blocking through the vane material. Cleaning is simple -- wipe individual vanes with a damp cloth or use a feather duster for regular maintenance.
Comparing Vertical Blinds to Other Wide-Window Options
Custom Blinds offers several options for large openings. Vertical blinds provide the smoothest traverse for sliding doors and wide windows. Roller blinds work well for standard windows but can be heavy at very wide sizes. Zebra blinds offer alternating sheer and opaque stripes for adjustable light. Duo roller blinds combine sheer and blockout in one mechanism. For sliding doors specifically, verticals remain the most practical and popular choice.
Installation
Standard installation uses a headrail bracket system mounted to the wall or ceiling above the opening. Installation takes approximately 20 minutes and requires a drill and spirit level. A step-by-step measuring guide is available at shop.customblinds.co.za. Garden Route customers in Knysna, George, Plettenberg Bay, Sedgefield, Mossel Bay, and Wilderness can book professional installation with Duncan Kane, the company founder.

Yes. Vertical blinds are the most practical option for sliding and stacker doors in South Africa. The louvres draw to one side to clear the opening completely, and the blockout option provides full privacy and light control when closed.
What width do vertical blind louvres come in?
Standard louvres are 89mm wide. Custom Blinds Shutters & Awnings supplies vertical blinds made to measure from 600mm to 5000mm total width, with drops up to 3000mm.
Can vertical blinds be motorised?
Yes. Somfy motorisation is available on vertical blinds from Custom Blinds. Contact our team on WhatsApp 076 022 8410 for motorised vertical blind options.
How long does delivery take for vertical blinds in South Africa?
Made-to-measure vertical blinds from Custom Blinds take approximately 5 working days to produce, with a further 2-5 days for free nationwide delivery to all South African addresses.
Do vertical blinds provide full blockout?
Yes. The blockout fabric louvres used by Custom Blinds Shutters & Awnings provide complete light blocking when the louvres are closed. There is a small light gap at each side seam, which is standard for all vertical blinds.
What is the difference between vertical blinds and roller blinds for a wide window?
Roller blinds for very wide openings require multiple blinds joined on one headrail, which can look heavy. Vertical blinds cover wide spans in a single system and stack cleanly to one side. For openings over 2400mm, vertical blinds are generally the better solution.
