Windbreaks for Patios: Screens, Hedges and Awnings That Work
The best windbreak for a patio is a permeable one: a slatted screen, a hedge or a mesh panel that filters the wind rather than blocking it, paired with shade that is rated for the gusts your site really gets. A solid wall looks like the obvious fix, but it throws wind over the top and drops it back as turbulence. For homes, pubs, restaurants, hotels and schools alike, the practical answer is a filtering screen on the exposed side and a wind-rated retractable awning or pergola overhead. We design, supply and install these across Yorkshire, Derbyshire, Nottinghamshire and Lincolnshire, so we know how a good plan comes together.
TL;DR
Aim for a barrier that lets roughly 50 to 60% of the wind through. Solid barriers create eddies; filtering ones calm the air behind them.
Shelter reaches the lee side for up to about ten times the barrier’s height, so a 1.8m screen helps a patio several metres deep, not the whole garden.
Overhead shade needs a stated wind class. A folding-arm awning is rated by nominal wind pressure, and it should be retracted before strong wind arrives.
Wind sensors help, but they are not failsafe. Fit them where they read the real wind and keep the factory settings.
Flats, listed buildings and conservation areas can need planning permission, so check before you fix anything to the façade.

Why a solid wall is the wrong windbreak
Wind behaves like water meeting a rock. Hit a solid wall and the air has to go somewhere: it rises, spills over the top and curls back down just behind the barrier. That is why a patio with a tall brick wall or a glass panel on the windward side can feel calm in one corner and oddly gusty in another.
The Royal Horticultural Society describes windbreaks as semi-permeable barriers and says they work best when they filter around 50 to 60% of the wind, which cuts its speed without creating damaging eddies. The same page says the sheltered zone on the lee side can extend up to ten times the height of the barrier.
Two practical numbers follow from that:
A 1.8m slatted fence gives useful shelter out to roughly 18m in open ground, with the calmest air much closer in.
A 1m screen shelters a seating area of a few metres, which is why low screens suit a terrace edge but not a large lawn.
For a patio, that means the screen should sit on the side the weather comes from, close enough to the seating area to matter, and tall enough to clear the heads of people sitting down.
Patio windbreak ideas that work
There are five families of windbreak, and most good schemes combine two of them. The right mix depends on how much space you have, whether the patio is a back garden, a roof terrace or a commercial frontage, and how much maintenance you will accept.
Hedges and planting
A hedge is the classic filter. The RHS notes that evergreen and deciduous hedges differ in privacy, maintenance and seasonal appearance: evergreens protect all year, while deciduous ones thin out in winter when you are using the patio least. Climbers on trellis are another option, and the RHS suggests combining screening with planting to soften hard edges.
The catch is time. A hedge takes seasons to reach useful height, so it suits homeowners planning ahead rather than a venue that needs shelter for next summer’s trading.
Slatted fencing and permeable panels
Fencing with gaps is the quickest route to a filtering barrier. The RHS recommends permeable lower-level screens and slatted fencing because they filter wind and avoid turbulence while keeping light and views. Look for roughly half open, half solid. Horizontal slats suit modern terraces; woven willow or hazel hurdles suit cottage gardens and are named by the RHS as workable options.
Mesh and netting
Woven or extruded plastic netting is the cheapest permeable barrier and is easy to take down. The RHS warns that screens taller than 1.5m may need professional heavy-duty strapping, because a tall panel catches a lot of wind and the fixings carry that load. On a commercial terrace, where staff and guests sit beside it all evening, secure fixing matters as much as the look.
Glass and framed screens
Glass keeps the view, which is why hospitality venues favour it. It is solid, though, so on its own it follows the wall rule above. Where a glass screen is used, it works best as a short side panel or with gaps, and with planting or slatting behind to filter what spills over. Rooftop and balcony terraces add a further job: whatever you fit must be supported without damaging the waterproof layer, a point Georgia Lindsay’s rooftop garden guidance stresses when it recommends zoning and partly open screening.
If your plan includes enclosing the edge of a terrace with glazed doors or sliding panels, terrace doors and screening shows how a lifting-sliding door system can close a space against the weather.
Side screens on an awning or pergola
This is the option that turns shelter and shade into one structure. A retractable side screen drops down from an awning, pergola or veranda on the windward edge, and rolls away when you want the breeze. You get the wind protection when you need it and an open patio when you do not. Side screens, weather sensors, LED lighting and heaters are all options we fit on our awnings and pergolas, so the whole thing is specified together rather than bolted on in pieces.
Wind-resistant awnings: what the claims mean
Searches such as “windproof awning” or “high wind awning” usually mean one question: will it survive a gust? The honest answer is in the wind class, not the marketing line.
Wind resistance for awnings is tested under the European standard EN 13561, which BSI describes as covering externally fitted blinds and awnings, including performance, safety, installation, operation and maintenance. It looks at the weakest point of the awning, the largest surface the wind can push on and the worst-case wind angle.
The classes themselves are set out as pressure. Under the regulation reproduced on legislation.gov.uk, folding-arm awning Class 1 means a nominal wind pressure below 70 N/m² and Class 2 means at least 70 N/m². The same text grades pergola awnings from Class 0 (below 40 N/m²) up to Class 6 (at least 400 N/m²).
In plain terms:
A higher class means the awning was tested against a stronger wind pressure.
The class is a tested limit, not permission to leave the awning out in a storm.
A pergola-type awning, which is held by posts and guided fabric, is tested on a different scale from a folding-arm model, so classes are not comparable across types.
For a deeper look at what each class means for British sites, our guide to awning wind classes 0, 1, 2 and 3 walks through it.
Retract before the wind arrives
The British Blind and Shutter Association (BBSA) is clear about use: wall-mounted folding-arm awnings without other support should be retracted when wind exceeds the manufacturer’s stated resistance class, and fully retracted before strong winds arrive, not once they are blowing. That is how you get years of use from a good awning: shade on calm sunny days, tucked away when the forecast turns.
Wind sensors: useful, not a guarantee
An electric awning with a wind sensor retracts on its own when gusts pass a set level, which is why we recommend them for any patio you cannot watch all day, such as a restaurant terrace or a school canopy. BBSA’s guidance adds two points worth knowing: sensors are not failsafe, and the owner stays responsible for making sure the awning is retracted, and the sensor limits must not be altered from the specified settings.
Position matters because a sensor in a sheltered corner reads calmer air than the awning feels. Our pages on wind sensors for awnings and where to place the sensor explain the options. A rain sensor is a sensible companion; our guide to rain sensor technology covers it.
Pitch, fixing and exposure
Pitch and fixing both affect how an awning copes outdoors. BBSA gives roughly 14° as an ideal pitch because it usually stops light rain pooling on the fabric and arms. The wall it is fixed to has to be sound, and exposed or coastal sites call for corrosion-resistant fittings; our note on coastal awnings and EN 13561 covers that case. For a general view of choosing and caring for a wind-resistant model, see wind resistance in awnings.
Matching the solution to your site
Different patios need different answers. Start with what the wind does on your site, then choose.
Site | Main problem | Sensible combination |
Back-garden patio, open to one side | Prevailing wind funnels across the seating area | Slatted screen or hedge on the windward side, retractable awning above |
Pub or restaurant terrace on a street | Gusts between buildings, guests seated for hours | Filtering screen at the exposed end, wind-rated awning with sensor, side screens |
Hotel or bar courtyard | Swirling wind, noise, need for year-round use | Pergola with side screens and heaters, planted or slatted boundary |
School or nursery outdoor area | Shelter for children, shade in summer, no one watching sensors | Fixed canopy or shelter sized for the site, wind-rated structure |
Roof terrace or balcony | Strong wind at height, waterproof layer to protect | Light permeable screening, supported without drilling through the membrane |
When choosing, work through four checks:
Find the wind direction. Notice where gusts arrive from over a few weeks. Put protection there, not on the sunniest side.
Measure what you need to shelter. Remember the ten-times-height rule: a taller screen reaches further, but a tall solid one creates stronger eddies.
Choose permeability. Aim for around half open. Anything much more solid needs a plant or gap treatment behind it.
Match the overhead structure to the exposure. A projecting awning on a windy corner needs a higher class than the same awning in a walled garden.
Permission and fixing
Before you fix anything to a building or raise a boundary, check the planning position. Permitted-development rights, the rules that let you do some work without applying, differ between England, Wales, Scotland and Northern Ireland and can be removed by Article 4 directions, conservation-area controls or other site conditions. Flats and maisonettes are treated differently from houses: the Welsh Government’s householder guide says that changes affecting the external appearance of a flat need permission, while internal alterations do not.
The rules are national, so your local planning authority is the place to confirm the position for your address, and a leasehold flat will also have a freeholder’s consent to consider. For a commercial terrace, pavement and street-frontage permissions come into play as well. When we survey a site, we cover the structure, the fixing and what is likely to be needed, so you know before you commit.
Maintenance keeps wind protection working
A screen or awning that was fixed well can loosen with years of gusting. Check bolts and brackets each spring, clean fabric, and look at the arms. If an arm looks bent after a gust, read our three checks before you replace it, and our guide on maintaining retractable awnings covers the routine. We also handle repair and maintenance, so an older awning does not have to be replaced to be put right.
Our view on patio wind protection
Most people ask us about wind after the first summer, when the lovely new patio turns out to be a wind tunnel. The cure is rarely one big item. It is a plan: shelter on the side the weather comes from, shade overhead, and controls that look after themselves. We work from 15 years of specifying awnings, pergolas and verandas across Yorkshire and the neighbouring counties, and we pick from Weinor, Llaza, Selt, Tarasola and Morvelle because each lets us match the structure to the exposure. We would rather talk through your site, your wind and your budget with no pressure than sell you a model that is wrong for the spot. For a home, that often means a retractable awning or pergola with a side screen on the windy edge. For a bar, restaurant or hotel, it means a terrace you can trade on in more kinds of weather. For a school, it means shelter that works without anyone needing to watch the sky. Andrew

FAQ
What is the best windbreak for a patio?
A permeable one. Slatted fencing, a hedge or mesh that lets around 50 to 60% of the wind through calms the air without creating eddies, according to the RHS. Place it on the windward side, close to where you sit. Adding a wind-rated awning or pergola gives shade as well.
How far does a patio windbreak protect?
The sheltered area on the lee side can reach up to about ten times the barrier’s height. The calmest air is closest to the screen, so a 1.8m screen suits a patio a few metres deep very well. Taller solid screens do not protect better, because they create turbulence.
Are there awnings for windy areas?
Yes. Awnings are tested to EN 13561 and given a wind class, and the higher the class, the stronger the tested wind pressure. Exposed sites need a higher class, a good fixing and, ideally, a wind sensor. The awning should still be retracted before strong wind arrives.
Do I need planning permission for a patio awning or screen?
Often not for a house, but it depends on where you are. Permitted-development rules differ across the four UK nations and can be restricted in conservation areas or by Article 4 directions. Changes to the outside of a flat generally need permission, so confirm with your local planning authority first.
