A good privacy screen reduces overlooking where it is actually a problem without removing more light, air or view than necessary. The right solution depends on whether it will be on a balcony, deck, patio, in the garden or at a window.
In this guide we compare glass, slats and trellises, plants, fences and solid fencing, fabric, screen walls and window film. You will get help choosing a solution based on position, daylight, maintenance, durability and how permanent the screening needs to be.
We also cover what to consider along the boundary and in blocks of flats, when planning permission or other rules may apply and how a privacy screen is affected if it is also part of a balustrade or other fall protection.
How do you choose the right privacy screening?
Choose the right privacy screening by first assessing where the overlooking comes from, what kind of space you want to screen and how permanent the solution needs to be. The distance to neighbours, a street or a footpath, how often the area is used and how exposed it is affect how much screening you actually need.
A ground-floor balcony next to a busy footpath, for example, has different needs from a deck with a clear view of your own garden. On a small balcony, space, wind and fixings are often decisive, while a larger patio or garden gives more freedom to combine plants, slats, fences or other privacy screening.
The goal isn’t always to prevent all overlooking. Well-designed screening should provide more privacy where it’s needed without blocking more daylight, air, or views than necessary. Once you know which sightlines are disruptive, it also becomes easier to determine whether you need to screen off the entire area or just one or two directions.
How much overlooking do you have?
First see where the overlooking actually comes from. It is often enough to screen against a neighbour, a street or a footpath in one direction instead of enclosing the whole balcony, deck or patio.
What kind of space is it?
Balconies, decks, patios, gardens, and windows each have different conditions. Space, wind, light, existing balustrades, and the possibility of fixing all influence which solution works best in that particular location.
How permanent should the solution be?
A temporary screen, fabric or planting can suit you when you want to be able to change the solution. Glass, slats and fences suit better when the screening should be a long-term, more permanent part of the space.
What types of privacy screening are available?
The most common types of privacy screening are plants and hedges, slats and trellises, fences and solid fencing, fabric or screen walls, window film and glass. Which option suits best depends on how much screening you need, how much light and air you want to keep and how permanent the solution should be.
The differences are also evident in terms of maintenance, durability, and cost. Plants, bamboo screens, and other lighter solutions may be easier to change over time, while a fixed fence, a slatted wall, or a glass solution becomes a more permanent feature of the balcony, deck, patio or garden.
| Type of privacy screening | Screening | Light transmission | Maintenance | Sustainability | Cost Level |
|---|---|---|---|---|---|
| Plants & Hedges | Varies by variety, density, and season | Medium to high | Watering, pruning, and routine care | Long-term, provided the plant thrives in that location | Varies depending on plant type and size |
| Slats & trellises | Medium to high, depending on the spacing | Medium to high | Depends on the material and surface treatment | Varies between timber, composite and aluminium | Often moderate |
| Fencing & solid screens | High with a dense structure | Low with solid fencing | Depends on the material and surface treatment | Medium to long | Often moderate |
| Awning fabric & screen wall | Medium to high | Low to moderate | Clean and inspect the fixings as needed | Shorter to medium, depending on the material and exposure | Often low to moderate |
| Window Film & Curtains | Varies depending on the solution and lighting conditions | Medium to high | Low | Short to medium | Often low |
| Frosted or tinted glass | Higher with frosted glass, lower with tinted glass | High | Clean as needed | Long | Often higher |
Which type of privacy screen works best on a balcony?
On a balcony, a privacy screen works best when it provides privacy without taking up unnecessary floor space or blocking out more light than you want. The balcony’s size, wind direction, existing balustrade, and the direction from which people can see in determine whether a fixed glass solution, fabric, plants, or another lighter privacy screen is the best fit.
Overlooking from a street or courtyard often comes at an angle or from below. So you don’t always need to screen the whole balcony. On many balconies it is enough to cover the lower part of the balustrade or the side facing the most intrusive sightline.
Which privacy screen is suitable for a deck or patio?
On decking or a patio there is often more freedom to choose and combine privacy screening than on a balcony. Plants, slats, trellises, screen walls, more solid structures and glass can be used separately or together, depending on where the overlooking comes from and how open you want the space to feel.
Start by identifying which sightlines are actually a nuisance. A patio rarely needs to be screened off equally on all sides. By screening the most exposed side, you can create more privacy while still maintaining light, air, and a view of the rest of the garden.
Screen where the overlooking actually comes from
Overlooking often comes from a neighbour, footpath or street in one or two clear directions. It is then usually better to concentrate the screening there than to enclose the whole deck or patio.
A more targeted solution also makes it easier to maintain a connection with the garden and prevent the patio from feeling enclosed. Plants or a trellis can be used where you want a softer transition, while a denser screen is best where overlooking is greatest.
Combine privacy screening and windbreaks
On exposed decking, the same screening may need to meet two needs. Glass can reduce wind while keeping daylight and views, while frosted or opal glass can also block direct overlooking.
You can also combine different materials. Glass along an exposed edge can provide shelter, while slats, a trellis, or plants can be used as a backdrop where you want more privacy and a softer look.
Which privacy screen works best along a property boundary and in the garden?
Along a boundary, hedges, fences, slats and trellises work well when you want to combine screening with a clear boundary around the garden. A solid structure gives more privacy, while a more open structure or planting keeps more light and gives a softer transition between gardens.
You don’t have to choose between fencing and plants either. A lower fence with climbing plants or a trellis can give gradually more privacy and be easier to adapt to the style of the house, the shape of the garden and how much screening is actually needed.
Choose based on maintenance and how open you want the boundary to feel
Hedges give green, soft screening but need time to grow and care over time. Timber slats and timber fencing can be adapted on site but usually need more regular surface maintenance.
Aluminium is an option when you want slats or fencing that need less painting and other surface treatment. How closely the slats are spaced also affects the balance between privacy, light and air.
Block the line of sight instead of the entire garden
A tall, dense screen around the entire property can make the garden darker and more enclosed than necessary. Therefore, start by identifying the one or two directions where the view into the property is most intrusive.
If the screen will stand close to your neighbour’s garden, it is also wise to talk about position and design before you build. This can make it easier to find a solution that works from both sides of the boundary.
Which window privacy screen works best?
The best privacy screening for windows depends on whether you want to see out, how much daylight you want to keep and whether it needs to work both day and evening. Frosted film gives more even privacy, while mirror film mainly suits situations where it is brighter outdoors than indoors.
Needs also differ between rooms. A bathroom usually needs screening at any time of day, while a living room often needs to keep more view and daylight. In bedrooms, blackout can be at least as important as the privacy itself.
Tailor the solution to how the space is used
Bathroom
Frosted window film or other opaque screening suits rooms where you need privacy both day and evening. Pleated blinds give more control over how much of the window is covered.
Bedroom
A roller blind or blackout curtain combines privacy with the ability to block out light when you're ready to sleep.
Living Room
Here, it’s often more important to maintain the view and let in natural light. Mirrored film can provide more privacy during the day, while sheer curtains or pleated blinds make it easier to adjust the level of privacy throughout the day.
Conservatories and large glazed areas
Frosted glass or film on side panels can screen exposed sightlines. For larger glazed areas, a vertical awning can be an option when you want to combine sun protection with more screening. How much overlooking it reduces depends on the density of the fabric and the lighting conditions, among other things.
Entrance and glazed door
Frosted glass or decorative window film on the lower part of the glass can reduce visibility where it is greatest without having to cover the entire glass panel.
Which material is most durable for privacy screening?
Aluminium, the right grade of stainless steel and glass can give a long service life outdoors with relatively little need for regular surface treatment. Timber can also last a long time, but the result depends more on the type of timber, wood protection, construction, finish and how exposed the location is to sun and moisture.
For privacy screening, it is therefore better to compare the whole solution than simply choose the material described as most durable. Fixings, construction, finish, wind exposure and regular cleaning affect how the material performs over time.
| Materials | Sustainability | Maintenance | Weather and exposure | Typical uses |
|---|---|---|---|---|
| Pressure-treated timber | Good when the right wood protection and construction are used | Cleaning and surface treatment as needed | Designed for outdoor use, but the surface is affected by sun and weather | More solid structures, slats and solutions built on site |
| Cedar | Depends on the quality of the timber, construction and exposure | Surface treatment to preserve colour and appearance | Untreated timber changes and turns grey over time outdoors | Slats and screens where the natural look of timber matters |
| Composite | Varies depending on the product and design | Usually cleaning rather than painting or oiling | Check the product specifications for UV, temperature, and humidity | Slats and screens with a timber-like appearance that require less maintenance |
| Aluminium | High when properly constructed and finished | Clean as needed | Naturally corrosion-resistant and can be given additional protection through surface treatment | Permanent slats, fences and screen walls |
| Stainless steel | High when the steel grade is suited to the environment | Cleaning is necessary to maintain the surface and appearance | The type of steel and exposure to salt and chlorides are particularly important | Posts, fittings, and other load-bearing or visible details |
| Laminated glass | High when the glass, edges, and fixings are designed correctly | Clean as needed | Does not require painting or oiling | Permanent solutions where light must be preserved |
| Awning fabric and textiles | Varies depending on the fabric, quality, and exposure | Cleaning and inspection of the fabric and fixings | Sun, wind, and moisture affect the material over time | Flexible or adjustable privacy screening |
Do you need planning permission for privacy screening?
Sometimes. It is not the term privacy screen that decides, but what you actually build, how tall and solid it is and where it is placed. An open fence and a tall, solid structure are often assessed differently, and the rules differ between places.
A loose fabric or movable screen is not automatically assessed in the same way as a fixed structure. For fixed structures, however, you need to be extra careful, particularly near the boundary, on the balcony of a flat or when the privacy screen also affects a balustrade or other fall protection.
Open fence
An open fence is normally lower and more open than a solid structure and is therefore often assessed more simply. If the structure becomes tall and solid, however, it may need to be assessed differently, so the design matters.
Tall and dense structure
For a tall, solid structure, the height, distance to buildings and position on the plot can decide whether planning permission is needed. The rules differ between places.
If the structure is mounted on top of a wall or a deck, the height of the entire structure may be taken into account, not just that of the screen itself.
Near a property boundary
A position near a boundary can affect what applies, even for work that could otherwise be done without planning permission. In some cases neighbours may need to be consulted.
On corner plots and near driveways, also consider visibility and road safety.
Balcony of a flat
If you live in a flat, check with the management company or building owner before making a permanent change outside your flat. This applies especially if the privacy screen is to be screwed into the façade, fixed permanently to the balcony or change the look of the balustrade or façade.
They may also have their own rules on materials, colour and how a balcony screen may be fitted, for example.
Balustrades and fall protection
If the privacy screen is fitted in, replaces or changes a balustrade, the balustrade’s safety function must still work. Fall protection needs to be designed for the use of the site and the drop height and follow the local building regulations.
Where young children may be present, there may also be specific requirements on climbing and openings, among other things. The fixings and the whole structure must therefore be assessed as fall protection, not just as screening.
Local rules for the area
Specific regulations for a particular area or property may affect what is permitted, for example, in protected environments. Therefore, always check the requirements for your specific location before you begin construction.
What should you check before choosing privacy screening?
Start by identifying where the overlooking comes from, how permanent the solution should be, and what dimensions and regulations apply at the site. This will make it easier to compare materials, light transmission, maintenance, and cost.
Go through these eight points
-
Identify the lines of sight
See where the overlooking actually comes from. It may be a neighbour, a street, a footpath or a home higher up. It is often enough to screen one or two directions instead of the whole area.
-
Determine how permanent the solution should be
Decide whether you need a portable or adjustable solution, plants that grow over time, or a permanent structure that will remain in place year-round.
-
Measure the area and note any obstacles
Measure the width and the height you need to screen. Also note corners, changes in level, existing balustrades, posts and other obstacles that affect position or fixings.
-
Check the rules at the location
Find out whether the solution is affected by planning permission, local planning rules, distance to the boundary or rules set by a management company or building owner. If the screen is to be fitted to a balustrade, the balustrade’s safety function must also be maintained.
-
Choose materials based on maintenance and the environment
Consider how much maintenance you’re willing to put in over time and how exposed the location is to sun, wind, moisture, and dirt. At the same time, the material’s appearance needs to complement the house and its surroundings.
-
Decide how much light and view you want to preserve
A completely solid screen gives more screening but can also reduce light and views. Glass, more widely spaced slats or targeted screening may suit better when you want to keep a more open feel.
-
Consider combining multiple solutions
You don't have to use the same privacy screen everywhere. Glass can be combined with plants, and slats or a trellis can be complemented with climbing plants where you want more privacy.
-
Calculate the entire solution
Start from your measurements and don’t just compare the price of materials. Posts, fittings, fixings, installation and future maintenance can also affect the total cost.
Start with sightlines, measurements and rules. Then choose materials and density based on how much screening, light, view and maintenance you want – and cost the whole solution before you decide.

What should you know about privacy screening?
Here are short answers to common questions about privacy screening for windows, balconies, decking and gardens.
Which type of privacy screening lets in the most light?
If you want to combine screening with plenty of daylight, frosted or opal glass is a strong option. Clear glass lets through plenty of light and a clear view but gives no real privacy. Widely spaced slats and perforated fabric can also let light through.
Can you install a privacy screen without drilling?
Yes. Self-adhesive window film, some fabric screens with ties or straps, and freestanding screens can be used without permanent drilling. On a balcony of a flat, you should still check the rules of the management company or building owner before fitting anything on the outside.
How tall does a privacy screen need to be?
There is no height that suits every situation. Start from the sightline and whether you mainly want to screen people sitting or standing. For a tall, solid structure, a position near the boundary or solutions that affect a balustrade, you also need to check which rules apply on site.
Does window film provide privacy at night?
Frosted or decorative film can give screening both day and evening, but also blocks the clear view through the glass. Reflective mirror film mainly gives privacy in the daytime when it is brighter outside than inside. When it is dark outside and the lights are on inside, it becomes easier to see in.
Do you need planning permission for privacy screening?
It depends on what you build, how the structure is designed and where it is placed. An open fence is often assessed more simply than a tall, solid structure, and the rules differ between places. Contact your local planning authority before you build if you are unsure.
Which privacy screen copes best with wind?
Wind resistance depends not just on the material but on the whole structure and its fixings. A fixed glass screen or windbreak can work well in an exposed location when the system is designed for the load. More solid structures catch more wind and therefore need sufficiently stable anchoring.
Can you combine privacy screening with a windbreak?
Yes. Frosted or opal glass in a structure intended as a windbreak can both reduce direct overlooking and give more shelter. Slats and fabric can also reduce both overlooking and wind, but the effect depends on how open the material is and how it is installed.
Is it possible to have privacy screening and still see out?
Yes, but the solution depends on the location. Reflective window film can give a clear view out and more privacy in the daytime when it is brighter outside than inside. You can also frost just part of a window or use slats and targeted screening that block one sightline but leave other views open.
Which privacy screen works best on the balcony of a flat?
Start with the rules of the management company or building owner. A loose or non-permanent balcony screen may be simpler than changing the balustrade or façade. If you need to drill into the façade, alter the balustrade or make a permanent change outside your flat, you will normally need their permission.
How much does a glass privacy screen cost?
The price depends on dimensions, glass type, posts or fittings, fixing system and site conditions. A made-to-measure glass system therefore has no single price that suits every project. Compare the whole solution, including fixings and any installation, when working out the cost.
