A screen wall on the patio can provide both privacy and shelter from the wind without taking up as much space as a hedge or blocking out the light like a solid fence.
With the right materials and placement, you can block out prying eyes, create privacy around your seating area, and still maintain an open feel. Glass is a good choice when light and views are important, while aluminium slats provide more privacy and a more distinct architectural look.
In this guide, we'll go over materials, placement, height, and regulations so you can choose a privacy screen for your patio that works both practically and aesthetically.
Why is a privacy screen an alternative to a solid timber fence or hedge?
A privacy screen provides immediate privacy, takes up little space, and allows more daylight to pass through than a solid fence. A newly planted hedge, on the other hand, often takes time to grow and requires more ongoing maintenance.
If the main goal is to create a privacy screen for the patio, the differences become particularly clear when you compare light transmission, space requirements, and maintenance. Frosted glass is an option when you want to reduce overlooking without blocking daylight.
| Point of comparison | Screen wall in frosted glass | Solid fence panel | Hedge |
|---|---|---|---|
| Impact in the first year | Privacy immediately after installation | Privacy immediately after installation | It depends on the size and density of the plants |
| Light transmission | High, but still partly see-through | Low through a solid fence | Varies depending on density and season |
| Space required (width) | Small | Small | Larger, depending on the plant variety |
| Maintenance | Cleaning and inspection of fixings | Cleaning and, in many cases, surface treatment | Pruning and ongoing care |
| Service life | Depends on the glass, the profiles and fixings | Depends on the material, design and maintenance | Depends on the plant variety and care |
| The winter months | The screening remains in place year-round | The screening remains in place year-round | May become sparser if the hedge is deciduous |
A screen wall made of “ frosted glass ” provides immediate privacy screen while allowing daylight to pass through. A dense fence creates a clearer visual boundary, while a hedge provides a green frame but requires more growing space and regular maintenance.
What is the best material for an outdoor screen wall?
The best material depends on whether you primarily want to preserve the view, reduce visibility from the outside, or create a more enclosed look. Glass is a good choice when light and the view are important, while powder-coated aluminium with slats provides more visual privacy and requires little ongoing maintenance.
- Glass
- Installed in aluminium profiles and available in clear, frosted, or tinted finishes. Clear glass provides windbreak without blocking the view. Frosted glass reduces visibility while still allowing diffused light to pass through.
- Aluminium with slats
- Combines privacy screen with a more open, airy look. Slats can be installed vertically or horizontally, and the orientation affects both the appearance and how sheltered the patio feels. Powder-coated aluminium typically does not need to be repainted or re-oiled on a regular basis.
- Combination
- Glass in one section and slats in another make it possible to customise the screen wall to meet different needs around the same patio. One possible layout is clear glass facing the view, frosted glass where you want to reduce visibility, and slats as a more enclosed finish on an exposed side.
Slat orientation
Should a screen wall have a portrait or landscape orientation slats?
Both orientations can create a privacy screen effect, but they interrupt sightlines in different ways and give the screen wall a different look. Therefore, consider where the view is coming from, how closely the slats should be spaced, and whether you want to emphasize a vertical or horizontal design language.
Vertical slats
Vertical design with varying visibility from the side
The vertical slats gives the screen wall a distinct vertical appearance. The degree to which it blocks the view depends on the distance between slats and the angle from which the patio is viewed.
Horizontal slats
Horizontal design with clear screening from the front
Horizontal slats create a more horizontal appearance and can provide greater visual screening from directly in front. Here, too, the spacing and angle of the slats affect how much light is allowed through.
Where should a screen wall be placed to provide the best shelter from wind and overlooking?
For windbreak, the windbreak should be placed on the side where the prevailing wind reaches the patio, before it hits the seating area. For privacy screen, the most important location is instead between the patio and the line of sight you want to block.
A straight screen wall is often sufficient when the house already provides shelter from one direction. If you need to create shelter or reduce overlooking from two directions, an L-shaped solution may work better. The same placement principle is important when planning a windbreak for your patio.
How tall should a privacy screen on a patio be?
About 150 cm can serve as a starting point when the windbreak is primarily intended to block the wind around a seating area. For privacy, even when people are standing, a taller screen—around 180–200 cm—may be appropriate. The correct height also depends on sightlines, how exposed the location is to the wind, and the structural requirements.
| Height | Best suited for | Things to Keep in Mind |
|---|---|---|
| About 150 cm | Windbreak around the seating area | Can provide protection when seated but offers less coverage when standing |
| Approximately 180–200 cm | More comprehensive privacy screening | Presents a larger surface to the wind and needs to be adjusted according to its location and fixing |
| Taller than about 200 cm | Tall, freestanding screen | Check the dimensions and stability, and determine whether the project requires a permit or other approval |
Do you need a building permit for an outdoor screen wall?
An outdoor screen wall may require planning permission or other authorization, depending on its design and location. Therefore, start by checking the structure’s height, location, and function before determining the dimensions and ordering materials.
Three things to check
What do you need to check before you start building?
-
Check the height and distance to buildings
The height, length, and location of the screen wall in relation to nearby buildings may affect whether a permit is required. Use the final dimensions as a guide and check the requirements before ordering a custom solution.
-
Check the position near the property boundary
If the screen wall is to be placed near a property boundary, you need to check the applicable placement regulations. There may be restrictions or requirements for approval or permits that are important to know before work begins.
-
Find out if a permit is required
Check which building codes and any required permits apply to the planned privacy screen. If you are unsure, contact the relevant building authority with a simple sketch showing the structure’s height, length, and location.
How can a privacy screen be integrated with the rest of the outdoor space?
A screen wall doesn’t have to solve every problem around the patio. Often, the result is better when each element has a clear function: the screen wall where you need shelter or privacy, fence where an area needs to be enclosed, and other solutions where the patio is more exposed to the wind.
Screen the areas most overlooked
Place glass or aluminium slats between your patio and the line of sight you want to block—for example, toward a walkway, a neighbour’s property, or a nearby seating area.
Create boundaries without using the screen wall everywhere
When the main purpose is to mark a boundary, a fence is often a better choice. The screen wall can then be reserved for areas where you actually need privacy or shelter from the wind.
Create shelter around the space you use the most
On a sheltered side, a windbreak, it can make the dining area or lounge more comfortable on windy days and make the patio more usable in the spring and fall.
If you’re planning multiple elements around the same patio, it’s a good idea to keep the colours, materials, and visual style consistent wherever the product lines allow. That way, the outdoor space will feel cohesive even when the elements serve different functions.
How much maintenance does a glass-and-aluminium partition wall require?
A partition wall made of glass and powder-coated aluminium requires relatively little ongoing maintenance. The glass needs to be cleaned, the aluminium parts need to be washed, and fixings needs to be checked at regular intervals, but the aluminium does not normally need to be repainted or oiled on a regular basis.
Ongoing maintenance
Three things to check throughout the year
-
Clean the glass as needed
Dirt, pollen, and rain splashes mainly affect the appearance. A standard window cleaner is usually sufficient for the routine cleaning of a glass screen wall.
-
Wash the aluminium parts
Aluminium profiles and slats at powder-coated can be washed with water when they get dirty. They normally do not require regular oiling or painting.
-
Check the screws and fixings
Check fixings about once a season to make sure nothing has come loose or changed, especially after periods of strong winds.
Maintenance at a glance
The most important thing is regular cleaning and a simple inspection at fixings. Recurring surface treatment of the aluminium at powder-coated is not normally necessary.
How do you choose the right screen for your outdoor space?
Start with the problem you want to solve, and then move on to placement, height, and materials. This will make it easier to determine whether the screen wall should primarily provide privacy screen, windbreak, or combine both functions.
Check before ordering
Six Questions to Help You Choose the Right Screen Wall
-
What do you want to screen off?
Determine whether the main issue is overlooking, wind or both that are a problem for your outdoor space. This factor affects both where the screen should be placed and which material is best suited.
-
Where does the wind come from?
Observe your patio on windy days and identify the most common wind direction. A windbreak is most effective when placed between the wind and the part of the patio you want to protect.
-
Is a straight privacy screen enough?
If the house already shields the patio from one direction, a straight screen wall may be sufficient. If wind or overlooking come from two directions, an L-shaped solution can provide better screening.
-
How tall does the privacy screen need to be?
A lower screen may be sufficient when the main aim is to shelter a seating area. To provide privacy even when standing, the screen wall will usually need to be taller.
-
How much daylight and how much of the view do you want to retain?
Clear glass is ideal when the view is important, frosted glass when you want to reduce visibility, and slats when you want to create a more distinct visual barrier.
-
What are the rules regarding the screen wall?
Check the location, height, and distance to property boundary before deciding on the design. If there is drop height, you also need to assess whether the location requires special protection against falls.
Next step
Which privacy screen is right for your patio?
Start by determining where you need protection and whether the main issue is privacy, wind, or both. Once the location and function are clear, it will be easier to choose the right height, material, and design.
What do you need to know about outdoor privacy screens?
Here are brief answers to common questions about height, planning permission, placement, materials, and stability when planning a screen wall for your patio.
How tall should a privacy screen on a patio be?
About 150 centimetres can serve as a starting point for the shelter around a seating area. For privacy, even when people are standing, a height of about 180–200 centimetres may be more suitable. Choose the height based on sightlines, wind, and the structural conditions.
Is a building permit required for an outdoor screen wall?
A screen wall may require planning permission or other authorization, depending on its height, design, and location. Check the requirements for your property with the relevant building authority before you begin construction.
Where is the best place to put a screen wall? windbreak?
Place the windbreak on the side where the prevailing wind hits the patio, between the wind and the area you want to protect. An L-shaped arrangement can provide better shelter when the wind comes from two directions, while a straight windbreak is often sufficient when the house already provides protection from one side.
What material is best for a patio privacy screen?
Frosted glass Ideal when you want to reduce visibility while still letting in plenty of light. Clear glass preserves the view and works well as a windbreak, while aluminium slats provide a more distinct visual barrier.
What is the difference between a screen wall, a solid fence and a hedge?
A privacy screen provides immediate privacy while allowing more light to pass through. A dense fence blocks out more light, while a hedge takes up more space in width, needs time to grow, and requires regular maintenance.
Does a wide privacy screen need intermediate posts?
A wide privacy screen may require intermediate posts to ensure the structure is stable and the wind load is distributed. Whether posts are needed depends on the privacy screen’s width and height, materials, fixing, location, and the system used.
Can a screen wall replace the balustrade on a raised deck?
Yes, but only if the entire structure—including the glass, posts, and fixings —is designed and dimensioned as described at fall protection. A standard windbreak or privacy screen is not automatically a safe railing.
