Terrace glazing price — what does the cost of glazing a terrace consist of?
If you are searching for information under the keyword “terrace glazing price”, you have most likely already decided that you want to glaze your terrace. The question is — how much does it cost and what do you get for your money?
The short answer: the price of terrace glazing depends on many factors and there is no single universal figure. But in this article we break down all the pricing components so you can understand exactly what you are paying for — and where it makes sense to save, and where it does not.
What does the cost of terrace glazing consist of?
The cost of glazing a terrace is not just the price of the glass. The total project cost consists of several components and each one affects the final sum.
The glazing system — framed or frameless
The biggest single price factor is the type of glazing system. Malmerk Klaasium offers three main solutions:
Framed sliding glass — aluminium-framed panels that move in profiles. The most common and versatile solution, top quality in its class. Suitable for most terraces.
Frameless sliding glass — glass panels without side frames, giving a cleaner and more modern appearance. The price is slightly higher than a framed system (thicker glass), but the quality is equally top-class in its own category.
Frameless folding glass — the most open solution, where the entire glass wall folds accordion-style to the side. The price depends on the opening height: up to ~2000 mm it is similar to a framed solution; at greater heights somewhat higher (thicker glass, stricter structural requirements) — not because the others are any less quality.
The price increases with system complexity and glass thickness — not with quality. All three are top quality in their class: Malmerk Klaasium profiles are substantial and strong (more aluminium than competitors at a similar look), with profiles that are easy to grip and slide. Frameless sliding glass is generally somewhat more expensive than a framed solution; frameless folding glass is similarly priced to a framed solution up to ~2000 mm opening height and somewhat more expensive above that — frameless terrace glazing is therefore not always more expensive.
Glass type
Terrace glazing uses toughened safety glass — this is a mandatory safety requirement. The thickness of the glass (typically 6–10 mm) directly affects the price: thicker glass is more expensive but also stronger and more wind-resistant. The choice of thickness depends on the panel size and wind load — in coastal Pärnu the wind load is greater than inland.
Optional extras that affect the price:
- Tinted glass — for solar protection and privacy. Can be a worthwhile investment for a south-facing terrace
- Energy-efficient glass — if you want to use the terrace in cooler weather and keep heating costs under control
- Laminated glass — a double layer of glass with a safety interlayer. Used in places where safety is a particular priority (elevated terrace, proximity to a children’s play area)
It is important to know that the choice of glass type is not merely aesthetic — it also affects the weight of the glass, which in turn affects the requirements for the profiles and structure.
Dimensions and opening size
The larger the glazed opening, the more panels are needed and the more complex the structure. A standard 3–4-metre opening is straightforward and affordable. But if you want a 6-, 8- or even 15-metre post-free opening, this requires special beams (steel or glulam timber), which add significantly to the cost.
Height also matters — taller panels are heavier and require a stronger profile system. The standard panel height is 2.0–2.5 metres. Taller solutions are possible, but the price increases accordingly.
The shape of the terrace also affects the price. A simple rectangular opening is the most cost-effective. Corner solutions, a multi-faceted terrace and an irregularly shaped structure require more engineering work and custom profiles.
The base structure and foundation
Here lies a component that most price enquiries overlook — yet it determines the success of the entire project.
Terrace glazing requires a stable base surface. The structural tolerance for Malmerk Klaasium frameless folding glass is only ±2 mm. For framed sliding systems it is ±7 mm. These are small numbers.
If your terrace was built without glazing requirements in mind — for example on a simple gravel base without a proper foundation — it may be necessary to reinforce the structure or even build a new foundation. This is an additional cost that many glazing companies do not mention, simply because they do not deal with construction work.
But this cost is unavoidable. Cheap glass on a poor structure = wasted money. Half a year later the glass panels jam and nobody takes responsibility.
Installation
Professional installation is an important pricing component. It includes measuring, fixing profiles, installing the glass panels, adjusting and carrying out final measurements. The installation price depends on the complexity of the project — a simple rectangular opening versus a multi-faceted corner solution involves very different amounts of work.
Extras
Terrace glazing can be supplemented with extras that affect the final price:
- Roller blinds — solar and privacy protection
- Insect screens — indispensable in summer
- Locking systems — for security
- Railings — safety railings along the terrace edge
Framed vs frameless — the price difference
Since framed and frameless terrace glazing prices differ considerably, it is worth examining this separately.
Framed terrace glazing is the more affordable choice. The aluminium frame gives the system rigidity and the structural tolerance is more lenient (±7 mm). This means that the base structure requirements are also more moderate — and the overall project cost remains lower.
The price of frameless terrace glazing is higher for several reasons:
- Glass panels are thicker and heavier (the frame provides no support)
- Profile systems are more complex and precise
- The structural tolerance is tighter — especially for folding systems (±2 mm)
- Installation requires greater precision
But the result of a frameless solution is also on a completely different visual level. A panoramic view without visible frames is something that cannot be conveyed in a photograph — it has to be experienced on site.
Which to choose? If your budget is limited and you want a good result at a reasonable price — go with framed sliding. If aesthetics are the top priority and you are ready to invest — frameless sliding or folding.
Why not look at the glass price alone?
This brings us to the most important point. Many homeowners request a price from a glazing company for the glass and separately from a builder for the structure. That seems logical — you get two quotes and pick the best.
In reality this creates a situation where:
- The builder does not know that the glazing system requires a ±2 mm tolerance
- The glazing company is not responsible for the builder’s structure
- If something goes wrong — neither party takes responsibility
The result: two quotes, zero guarantees.
Why is one quote better than two?
When one company is responsible for the entire project — from foundation to glass — the dimensioning is correct from the very start. The foundation and structure are built to the requirements of the glazing system. Tolerances are verified. And if something shifts, there is one responsible party.
This does not necessarily mean a higher price. Coordinating two companies, separate mobilisations and logistics, and any mid-project corrections often end up costing more overall than a single full-service solution.

What is the approximate price of terrace glazing?
We give a ballpark figure so you can plan your project — but these are APPROXIMATE ranges: terrace glazing is bespoke work and the final price is always determined by a free on-site measurement and quote.
Framed sliding system (price includes glass, installation, transport and full kit):
- Smaller opening glazings — from ~800–1400 €
- Medium projects — ~1400–3000 €
- Larger projects — ~3000 € and above
The price is affected by dimensions (panel height is typically 2.0–3.0 m), whether the terrace is set into a recess, and the distance and transport to the installation site.
Frameless sliding glass is generally somewhat more expensive than a framed solution (thicker glass required for the necessary system strength). Frameless folding glass depends on the opening height: up to 2.0 m the price is similar to a framed solution, up to 2.5 m generally ~15% more, and up to 3.0 m ~30% more. Frameless therefore does not always mean more expensive — for a low opening, folding glass is similarly priced to framed.
A more expensive system does not automatically mean a better one. Each solution — framed sliding, frameless sliding and frameless folding — has its own pros and cons; the best choice depends on the property, location and intended use. Talk to us: we will recommend the solution that best fits your needs.
These are rough ballpark figures, not a fixed price list. Below we explain why the final price is shaped by your specific project — and why that works in your favour.
Every terrace is different. The price of a glazing system depends on the specific combination: system type (framed sliding, frameless sliding or frameless folding), glass thickness and type, number and height of panels, opening geometry, corner solutions and accessories. Different combinations of these factors produce a different result every time.
The structure determines half the price. The condition of the existing terrace, the strength of the foundation, structural tolerances — these affect the final price just as much as the glass itself. Without an on-site assessment it is not possible to say whether your terrace needs only glass or also structural reinforcement.
Site conditions matter. The wind load in a coastal area is completely different from that inland. A south-facing terrace requires different solutions from a north-facing one. These differences affect both the glass selection and the structure — and therefore the price.
This is to your advantage. A fixed price list would mean a one-size-fits-all solution for everyone. An individual quote means you get a solution tailored exactly to your terrace and needs — neither over- nor under-dimensioned, but precisely right. And the price reflects what you actually receive.
For this reason every project begins with an on-site measurement and structural assessment. This is the only way to provide a fair and accurate quote with no hidden costs and no later surprises.
An important reminder: a lower-priced quote does not always mean a cheaper project. If a quote does not include a structural inspection, foundation assessment or installation, these costs will be added later — and often to a greater extent than originally planned.

FAQ: Terrace glazing price
How much does it cost to glaze a terrace?
As a ballpark, framed terrace glazing (including installation, transport and full kit) starts at ~800–1400 € for smaller openings, ~1400–3000 € for medium projects and ~3000 € and above for larger ones. Frameless sliding glass is generally somewhat more expensive; frameless folding glass, however, is similarly priced to a framed solution up to ~2000 mm opening height (somewhat more expensive at greater heights). These are rough ballpark figures — the exact price depends on the glazing system, dimensions, condition of the structure and extras, and is always determined by a free on-site measurement and quote. Get a quote — the measurement visit is free.
Is frameless terrace glazing always more expensive?
No, it depends on the system and opening height. Frameless sliding glass is generally somewhat more expensive than a framed solution. Frameless folding glass, however, is similarly priced to a framed solution up to ~2000 mm opening height and only somewhat more expensive at greater heights. Folding glass requires a ±2 mm tolerance, which demands a particularly stable base structure. The exact price is determined by measurement and quote.
Why do quotes from different companies vary so much?
Because quotes include different things. One company offers only the glass, another offers glass plus installation, a third offers the complete solution including the structure. Always compare what a quote includes — not just the total figure.
Is a cheaper quote always worse?
Not necessarily, but it is important to understand what it includes. If a cheap quote does not include a structural inspection and foundation assessment, you may end up paying more for corrections later than the savings were worth. A stable base is a prerequisite for the glazing system to function properly.
