Furnishing a flat balcony can be a real challenge, especially if you want to combine good looks, durability and easy maintenance. One material that is becoming increasingly popular is composite decking. But is it suitable for a flat balcony? What are its advantages and disadvantages? In this article, you’ll find everything you need to know before choosing this material.
What is composite decking, and why has it become popular?
Composite decking is a modern material made from a mixture of wood fibres and plastic. This combination gives it the appearance of natural wood, while making it much more durable and resistant to weather conditions.
It has become popular for both terraces and balconies because it:
- Is resistant to moisture, mould and UV radiation.
- Does not require time-consuming maintenance like natural wood.
- Is available in a range of colours and textures, so it suits many different designs.
Composite decking works very well on flat balconies because it is lightweight, durable and easy to install – especially important when space is limited.
Advantages of composite decking for a balcony.
Choosing composite decking for your balcony can bring many benefits:
- Durability and resistance to weather conditions: Composite decking boards are resistant to moisture, frost, rain and sunlight. This means you don’t need to worry about your balcony losing its attractive appearance after one winter.
- Easy to keep clean: Unlike wood, composite decking does not require impregnation, painting or special care products. Simply wipe it with a damp cloth or wash it with water to make it look like new.
- Attractive appearance: Composite decking boards look remarkably like natural wood, but are available in a range of shades and textures. This means you can match them to the style of your flat – from classic to modern.
- Safety: Composite decking boards are non-slip, which is particularly important on balconies where moisture can accumulate. They are also free from splinters, which families with children and pets will appreciate.
- Easy installation: Composite decking boards are lightweight and easy to install. You can often install them yourself, saving on the cost of a professional installation team.

Disadvantages of composite decking – what to watch out for?
Of course, like any material, composite decking also has its disadvantages:
- Price: Although prices for composite decking boards are falling, they are still more expensive than traditional balcony tiles or floor coverings. However, it is worth remembering that their durability and lack of need for maintenance make up for this cost in the long run.
- Heating up: On hot days, composite decking boards can heat up, which may be an issue if you want to walk on the balcony barefoot. It is worth choosing lighter shades, which absorb less heat.
- Structural limitations: Some balconies in older blocks of flats may have load restrictions. Make sure the balcony structure is strong enough before deciding to install composite decking boards.
How to choose the right composite decking for a balcony?
When choosing composite decking boards for a balcony, it is worth considering a few key aspects:
- Thickness and weight – for balconies, it is best to choose lightweight boards that will not put a strain on the structure.
- Resistance to UV radiation – make sure the boards are resistant to fading in sunlight.
- Installation system – choose boards with an easy installation system, for example using special clips.
- Appearance – match the colour and texture of the boards to the style of your flat and its surroundings.
How much does composite decking for a balcony cost?
The price of composite decking boards depends on the manufacturer, the quality of the material and the design chosen. On average, it costs from 100 to 250 zł per square metre. You should also add the installation costs (if you are not doing it yourself) and any accessories, such as joists or fixing clips. Although the initial outlay may seem high, the lack of need for maintenance and the long life of composite decking boards make this an investment that will soon pay for itself.
How to install composite decking on a balcony?
Installing composite decking on a balcony is simpler than you might think. Here are the basic steps:
1. Preparing the surface.
Make sure the balcony surface is level, clean and dry.
2. Laying the joists.
Lay the joists (special support beams) on the surface; they will form the base for the decking boards. It is important to maintain an even spacing between them.
3. Fixing the decking boards.
Composite decking boards are installed using special fixing clips, which provide stability and an attractive appearance.
4. Cutting the decking boards to size.
Finally, cut the decking boards to the right size so that they fit the balcony surface perfectly.

Composite decking board is an excellent choice for a flat balcony, especially if durability, appearance and easy maintenance are important to you.
