Spring 2026 is the ideal time to transform often neglected spaces into functional, year-round havens. We compare 7 strikingly different solutions, from budget-friendly to premium, to help you make the best decision.
What is a balcony enclosure and why is it gaining popularity in 2026?
A balcony enclosure involves installing a system of glass panels, windows, or other barriers to shield an open balcony or loggia. Its purpose is to protect against weather conditions and noise, and to create an additional, usable space throughout the year. The rapid increase in popularity of this solution in 2026 stems from rising property prices and the search for ways to maximise every square meter of living space.
Industry experts confirm: people are no longer treating balconies as storage for bicycles and clothes dryers. They have begun to see their potential to create a home office, a relaxation corner, a mini-conservatory, or a safe play area for children. Modern systems, both framed and frameless, offer aesthetics and functionality incomparable to solutions from a decade ago, further driving this trend.
How much does a balcony enclosure cost in 2026? Price overview
The average cost of a balcony enclosure in 2026 ranges from approx. €1,160 to €5,815, depending on the chosen technology, balcony size, and material standards. The cheapest are framed aluminium systems (approx. €105-165/sqm), while the most expensive, panoramic HS (HST) sliding patio doors, can reach prices of approx. €580-815/sqm.
Key factors influencing the final price include:
- System type: Frameless systems are typically 20-40% more expensive than framed ones due to more complex installation and tempered glass.
- Profile material: Aluminium is cheaper, PVC (uPVC) offers better insulation at a similar price, and timber or timber-aluminium systems belong to the premium segment.
- Glass type: Standard single glazing ("cold" systems), double or triple glazing units ("warm" systems), safety glass, tempered glass, acoustic glass, solar control glass – each option increases the price.
- Balcony size and shape: Balconies with non-standard shapes (e.g., semicircular) require individual designs and more expensive solutions.
- Additional elements: Vents, insect screens, internal blinds, sills, or additional seals are further cost considerations.
We've checked it – here are the facts: Investing in a "warm" enclosure with triple glazing, although more expensive initially, can pay for itself within 7-10 years due to heating savings. Check our configurator and get an accurate quote for your windows and doors online in just 2 minutes.
What are the key differences between balcony enclosures and patio doors?
The main difference lies in the level of thermal insulation and intended use. A classic balcony enclosure (especially a framed one) creates a buffer zone (a "cold garden"), while patio doors (HS, PSK) are designed for installation in a heated living area, offering thermal parameters identical to standard facade windows.
A balcony enclosure's primary task is to protect against wind, rain, and noise. Patio doors, on the other hand, provide a full thermal barrier, allowing the balcony or terrace area to be integrated into the living room, creating a seamless, heated space. This distinction is fundamental to understanding the differences in price and design possibilities.

How does a framed system work and who is it best for?
A framed system is a structure where each pane of glass is set in a separate aluminium or uPVC frame. Individual segments slide on rollers along tracks installed on the floor and ceiling of the balcony. This is a reliable and economical solution, ideal for those who want to shield their apartment balcony from wind and rain with the lowest possible budget.
The advantage of this system is its simplicity, durability, and relatively easy installation. Individual sashes can be easily slid and positioned as desired. The disadvantage, however, is the aesthetics – vertical and horizontal frame profiles reduce light and divide the view into smaller sections. Nevertheless, due to its unbeatable price, it remains the most popular choice in residential associations and housing cooperatives.
What characterises a frameless balcony enclosure?
A frameless balcony enclosure is a sliding-folding system where tempered glass panels have no vertical frames. This creates the illusion of a continuous, smooth glass wall, providing an unobstructed, panoramic view. This is a solution for design connoisseurs who value minimalism and modern aesthetics.
The glass panels in this system slide along a top track, and upon reaching the side wall, fold inwards like cards, opening up almost the entire balcony area. The surprising conclusion is that although it looks incredibly light, this system is very safe thanks to the use of thick, tempered or laminated glass. The main disadvantage, apart from the higher price, is less effective sealing compared to framed systems, making it a typical "cold" enclosure.

When is it worth choosing HS/HST sliding patio doors?
HS (HST) lift and slide patio doors are worth considering when the goal is to fully integrate a terrace or balcony with the living room and create one large, heated space. This is a premium solution that, thanks to its special design, allows for huge glazing (even several meters wide) and offers a so-called low threshold, meaning an almost flat transition to the outside.
Data clearly shows: the HS system offers the highest user comfort and the best thermal insulation parameters among all sliding systems. After turning the handle, the sash lifts a few millimeters and slides along a separate track effortlessly. If you are planning to build a modern home with access to the garden or want to transform a large terrace in an apartment building into a winter garden, modern HS (HST) sliding patio doors are an unbeatable, though the most expensive, choice.
What are the advantages of PSK tilt and slide patio doors?
PSK tilt and slide patio doors offer very good thermal and acoustic insulation at a significantly lower price than HS systems. Their main advantage is the mechanism, which allows not only for the sash to slide but also to tilt, providing convenient ventilation of the room without needing to open the entire door.
The PSK system is a clever compromise between price and functionality. It operates based on standard window profiles, which reduces production costs. The sash first moves away from the frame inwards, then slides sideways along a track installed at the bottom of the frame. The biggest drawback of this solution is the relatively high threshold, which hinders passage, and the limited maximum sash dimensions compared to HS. It's an excellent choice for smaller balcony or terrace exits in homes and apartments where budget is a significant factor.
Are external screens an alternative to a full enclosure?
External blinds, especially modern screen blinds, are an alternative, but only in terms of protection against sun, wind, and insects. They do not constitute a full enclosure, as they do not protect against rain, snow, or cold and do not create an enclosed volume. Their primary function is to reduce heat gain in rooms during summer.
Made from a special fibreglass mesh covered with PVC (uPVC), screen blinds block up to 90% of sunlight before it reaches the glass, drastically lowering the indoor temperature. Crucially, they maintain visibility to the outside. They can be a great complement to fixed glazing (Fix) or patio doors, but they cannot replace a full enclosure if the aim is to create an additional, sheltered room.

What is the fixed glass panel (Fix) system?
The fixed glass panel system, commonly known as "fixes" or fixed glazing, involves installing glass panes directly into a structural frame without the possibility of opening them. This is the simplest and most economical way to achieve large, non-opening glazed areas. It is used to bring light into rooms and as an element of larger constructions, for example, in combination with balcony doors or sliding windows.
Clients most often ask about using fixed panels on balconies. They are ideal as side or bottom panels in enclosures where a movable segment is not needed across the entire width. The main advantages are a lower price compared to opening windows of the same dimensions, better sealing, and the ability to create very large glazed areas. However, it should be noted that they prevent ventilation and require cleaning from the outside.
Why are winter gardens a premium solution?
Winter gardens are a premium solution because they represent a fully integrated, heated, and insulated structure that creates an entirely new living space. They require solid foundations, advanced architectural design, and the use of "warm" profiles (aluminium with thermal breaks or uPVC) and triple glazing units, which significantly drives up their price above a standard balcony enclosure.
The cost of building a winter garden is comparable to the cost of building a small room. It is an investment that genuinely increases the usable area of the home and raises its market value. A winter garden is not just a sheltered terrace, but a living room, dining room, or study with panoramic views of the garden, comfortably used 365 days a year. This level of integration and functionality defines it as a luxury product.
Do I need permission for a balcony enclosure?
In most cases, a standard, lightweight balcony enclosure in an apartment block (framed or frameless system) does not require planning permission, but it is necessary to report the works to the building administration (housing cooperative or residents' association). The administration may have its own regulations specifying the permissible appearance and type of enclosure to maintain facade consistency.
Our analysis indicates that the situation becomes more complicated when the enclosure:
- Interferes with the building's structure (e.g., requires breaking into the balcony slab).
- Extends beyond the balcony's footprint.
- Is installed in a listed building.
- Involves the construction of a full winter garden on a ground-level terrace.
In such situations, reporting building works to the local authority or even obtaining planning permission may be required. It is always advisable to start by visiting your building's administration – it is the most reliable source of information.
How to prepare your balcony for enclosure installation?
Proper preparation of the balcony is crucial for efficient and durable installation of the enclosure. Ensure that the surfaces to which the tracks will be attached (floor, ceiling, side walls) are even, stable, and load-bearing. Any old, peeling coatings, tiles, or plaster must be removed or repaired.
Here is a simple checklist to help with preparations:
- Clear the balcony: Remove all furniture, planters, dryers, and other items.
- Assess the floor condition: Check if tiles are cracked or detached. The floor must be level and have an appropriate slope outwards.
- Check the ceiling and walls: Ensure plaster is not falling off. Surfaces must be solid for stable mounting of anchors.
- Repair imperfections: Any cracks and unevenness should be filled with frost-resistant leveling mortar.
- Check the balustrade: Ensure the balustrade is securely fastened. Enclosure systems are often mounted to its inner side.
A professional installation team should verify the balcony's condition before starting work, but performing these steps beforehand will significantly speed up the entire process and help avoid unforeseen costs associated with additional renovation work. Investing in warm installation for patio doors and proper substrate preparation guarantees airtightness for years.
