Sheerweave Blinds for Patios in South Africa
You want wind protection without losing the view. Sheerweave mesh blinds do exactly that. Here is how they work, which openness factor to choose, and why they have become the default for serious patio enclosures across South Africa.
What are Sheerweave blinds and why are they used on South African patios?
- Sheerweave is a woven mesh fabric made from PVC-coated fibreglass or polyester yarn, designed specifically for outdoor blinds that need to block wind and UV while preserving outward visibility
- Openness factors range from 1% (tightest weave, maximum wind and UV block) to 14% (most open, maximum airflow). For most patios, 5% openness is the best all-round choice in South Africa
- Sheerweave filters up to 95% of UV radiation depending on the weave density, protecting furniture, flooring and skin from sun damage
- The fabric is inherently mould-resistant and does not absorb moisture, making it suitable for coastal humidity on the Garden Route, KZN coast and Cape Town seaboard
- Custom Blinds installs Sheerweave outdoor blinds across the Garden Route and ships nationally from the online shop with free delivery
The view is why you chose the house. The patio is where you live in it. Sheerweave keeps the wind out and the feeling of being outside in.
What is Sheerweave and how is it different from other outdoor blind fabrics?
Sheerweave is a woven mesh fabric made from PVC-coated fibreglass or polyester yarns, woven into a structured mesh with precisely controlled openings between the threads. That controlled openness is what makes Sheerweave different from solid PVC, canvas, or acrylic outdoor blind fabrics.
Where solid PVC seals a space completely (blocking rain but also trapping heat and eliminating airflow), Sheerweave lets air pass through while cutting wind speed significantly. The mesh structure also maintains outward visibility. During the day you can see the garden, the ocean, or the mountains clearly from inside the enclosed patio. From outside looking in, the view is obscured, which adds a layer of privacy for evening entertaining.
Sunworker is the other major mesh brand used in South Africa. It works on the same principle as Sheerweave with similar performance characteristics. Both are UV stabilised, fire retardant, and resistant to mould growth. Custom Blinds specifies either depending on the application, colour availability, and client preference.
What openness factor should you choose for a patio blind?
Openness factor is the single most important specification when choosing a Sheerweave blind. It measures the percentage of the fabric surface that is open space between the woven threads. A lower number means a tighter weave with more protection. A higher number means more open space with more airflow and visibility but less wind and UV blocking.
1% openness: The tightest standard weave. Blocks approximately 95% of wind and 99% of UV. Visibility is reduced to a soft haze. Best for fully exposed cliff-top and beachfront positions where wind is the primary concern and the view is secondary to shelter.
3% openness: A tight weave popular for fully exposed patios. Blocks roughly 85% of wind and 97% of UV. You can see the garden and the view clearly from inside. From outside, the patio appears dark and private. Good for beachfront and cliff-top homes where wind is relentless.
5% openness: The best all-round choice for most South African patios. Blocks approximately 75% of wind and 95% of UV with noticeably clearer visibility and natural airflow. You get genuine wind protection while still feeling like you are outdoors. This is what we recommend for braai areas, dining patios, entertainment spaces, restaurants, and lodges.
10% to 14% openness: High airflow, minimal wind reduction. Used primarily for sun screening on windows and facades rather than patio enclosures. Not recommended for exposed patios where wind is a factor.
How to decide: If wind is your main problem, go tighter (1% to 3%). For the best balance of protection and outdoor feel, 5% is our recommendation for most patios. Contact Duncan on 079 523 5407 to discuss your specific site.
Sheerweave openness factor comparison
| Openness | Wind block | UV block | Visibility | Best for |
|---|---|---|---|---|
| 1% | ~95% | ~99% | Soft haze | Exposed coastal, cliff-top |
| 3% | ~85% | ~97% | Clear view out, private from outside | Exposed beachfront, high-wind patios |
| 5% | ~75% | ~95% | Very clear both directions | Most residential patios, braai areas, restaurants |
| 10%+ | ~50% | ~90% | Fully transparent | Sun screening, not wind protection |
How do Sheerweave blinds handle coastal conditions in South Africa?
Coastal environments test every building material. Salt air corrodes metal. UV degrades plastic. Humidity promotes mould. Wind loads stress mounting points. Sheerweave is engineered specifically for these conditions. The PVC coating on the fibreglass yarns resists salt corrosion and UV degradation. The open weave structure means the fabric does not trap moisture the way solid canvas or acrylic does, so mould cannot take hold on the surface.
On the Garden Route, where the south-easterly wind is the dominant weather factor, sidetrack channel-guided systems are essential for Sheerweave installations. The fabric runs inside aluminium channels on each side of the opening, preventing billowing. Without tracks, a mesh blind in a Knysna south-easter will flap, stretch, and eventually tear loose from its mountings. With tracks, the wind force transfers through the channels into the building structure and the fabric stays taut.
For beachfront properties in Plettenberg Bay, Mossel Bay, and along the KZN coast, stainless steel hardware is specified instead of standard zinc-plated fittings. The cost difference is minor compared to replacing corroded brackets after two seasons. Custom Blinds specifies marine-grade components as standard for all coastal outdoor blind installations.
Can you combine Sheerweave with other outdoor blind fabrics?
Yes, and combination installations are one of the most effective ways to enclose a patio. The typical configuration uses Sheerweave mesh on the wind-facing and sun-facing sides (where you want UV protection and airflow) and clear PVC on the rain-exposed side (where you need a complete seal against water).
This gives you the best of both materials. The mesh sides breathe, filter light naturally, and keep the braai smoke venting outward. The PVC side blocks driving rain completely. When everything is closed, the space feels enclosed and protected without feeling sealed in. For a full comparison of outdoor blinds and overhead shade options, see the outdoor blinds vs awnings guide.
How do you clean and maintain Sheerweave outdoor blinds?
Sheerweave is one of the lowest maintenance outdoor blind fabrics available. The PVC coating prevents dirt from penetrating the weave, so surface cleaning is usually all that is needed. Hose the blinds down with fresh water every few weeks to remove dust and salt deposits. For stubborn marks, use a soft brush with mild soapy water and rinse thoroughly. Avoid high-pressure washers as these can force water into the mounting hardware.
On the Garden Route, bird droppings and pollen are the main cleaning challenges. Both come off easily when fresh but set hard in sunlight, so a fortnightly rinse during spring and summer prevents build-up. The fabric does not need re-waterproofing, UV treatment, or any chemical application over its lifetime. For a complete care guide across all blind types, see how to clean blinds in South Africa.
“Sheerweave is what we install most on Garden Route patios. It handles the south-easter, it handles the salt, and people are always surprised at how clearly they can still see the view through it. The 5% is what we fit most. It gives you proper wind protection and you can still see everything.”

Should you motorise Sheerweave patio blinds?
For blinds wider than 2.5 metres or in hard-to-reach positions, motorisation makes practical sense. Somfy motors apply even tension when raising and lowering, which extends fabric life compared to manual crank or rope operation where uneven force can stretch one side of the mesh. Wind sensors retract the blinds automatically if conditions exceed a preset threshold, protecting the installation when you are not home.
For holiday homes on the coast, automated wind retraction is particularly valuable. A storm can blow through while the property is empty, and a motorised system protects itself without human intervention. Somfy integrates with remote controls, wall switches, and smartphone apps for convenient daily operation.
Frequently Asked Questions
What is the difference between Sheerweave and Sunworker outdoor blinds?
Both are woven mesh fabrics designed for outdoor use with similar UV protection, wind reduction, and mould resistance. The main differences are in the colour range and specific weave patterns available. Custom Blinds specifies either depending on the project requirements.
How long do Sheerweave blinds last in South African conditions?
With proper installation and basic maintenance (regular hosing), Sheerweave outdoor blinds typically last 8 to 12 years in coastal conditions and longer in sheltered inland positions. The fabric is UV stabilised to resist degradation from South African sun intensity.
Can Sheerweave blinds block rain?
No. Sheerweave is an open mesh fabric designed for wind and UV protection, not rain sealing. The same 5% openness that lets a breeze through on a hot day will also let a fine mist through in heavy, driving rain. That is how the fabric works. For full rain protection, use clear PVC blinds on the rain-exposed side and Sheerweave on the other sides. Most patio enclosures use this combination.
Are Sheerweave blinds suitable for braai areas?
Yes. The mesh structure allows smoke to vent through the fabric while blocking wind. A 3% to 5% openness factor is ideal for braai areas because it provides wind protection without trapping smoke inside the enclosed space. See the full braai area outdoor blinds guide.
Can I order Sheerweave outdoor blinds online in South Africa?
Yes. Custom Blinds ships outdoor blinds nationally with free delivery. Measure your openings using the included guide, select your fabric and openness factor, and order through the online shop. For Garden Route residents, Duncan conducts free on-site assessments.
What colours are available in Sheerweave?
Sheerweave is available in a range of neutral tones including charcoal, grey, beige, white, and bronze. Charcoal is the most popular for South African homes because it reduces glare most effectively while blending with contemporary architecture. Duncan can advise on the best colour for your specific setting.
