How much does it cost to enclose a terrace in 2026 – comparison between glass, PVC and adjustable blinds
Enclosing a terrace or pergola is one of the most popular arrangements for outdoor spaces.
A terrace protected from wind, rain and sun can be used much more often and quickly becomes one of the most pleasant places in the house.
However, before choosing a locking system, most people ask themselves the same question:
How much does it cost to close a terrace and which solution is worth choosing?
In this article we compare the most used variants in Romania.
1. Enclosing the terrace with tempered glass
Tempered glass is one of the most elegant solutions for enclosing a terrace.
This system offers a complete view to the outside and a modern look.
Advantages
• premium look
• full visibility
• good resistance over time
disadvantage
• very high cost
• limited ventilation
• heavy system and difficult to modify later
Estimated cost
Enclosing a terrace with tempered glass can cost approximately:
👉 1200 – 2000 RON / m²
This makes glass one of the most expensive solutions for pergolas and terraces.
2. Closing the terrace with PVC roller blinds
Another common solution is to use transparent PVC curtains .
These are usually mounted on the terraces of restaurants or guesthouses.
Advantages
• lower cost than glass
• relatively quick assembly
• good protection against rain
disadvantage
• less aesthetic appearance
• limited lifespan
• the material may yellow or crack over time
Estimated cost
👉 600 – 900 RON / m²
3. Closing the terrace with adjustable blinds and metal sliders
An increasingly popular solution in recent years is to enclose the terrace with sliding panels and adjustable blinds .
This system uses:
-
metal slides mounted on the structure
-
wooden or metal slats
-
panels that can be opened or closed depending on the weather
The result is a flexible and modern terrace.
Estimated cost for adjustable blinds
A metal sliding system with Nordic pine slats can cost approximately:
👉 from 368 RON / m²
Indicative calculation:
-
LUMINAL slides: 170 RON / meter
-
Nordic pine slats: 11 pieces × 18 RON
Total cost:
170 RON + 198 RON = approximately 368 RON / m²
This makes adjustable blind systems for pergolas and terraces one of the most affordable closing solutions.
Comparison between the three systems
| System | Approximate cost | Flexibility | Durability |
|---|---|---|---|
| Tempered glass | 1200 – 2000 RON / m² | LOW | very good |
| PVC roll | 600 – 900 RON / m² | average | average |
| Adjustable blinds | from 368 RON / m² | very large | good |

The popularity of sliding and slatted systems is growing rapidly because they offer a very good balance between cost, aesthetics and flexibility.
The main advantages are:
✔ affordable cost
✔ quick assembly
✔ possibility to completely open the terrace

In addition, these systems can be used for both residential pergolas and Horeca terraces .

• glass offers a premium look, but is very expensive
• PVC is more affordable but less durable
• directional blinds offer a good balance between cost, flexibility and design
That is why systems with metal slides and adjustable slats are becoming increasingly popular for arranging terraces and pergolas.
