Are you planning a terrace or balcony development and wondering how much a square metre of external blinds (m2) costs? In this guide, we show you how to calculate the price of your OpenUp movable decking yourself, so you can easily compare quotations and plan the budget for your development.

Why is it important to know the price per square metre of external blinds?

Wondering how much a square metre of external blinds costs? This is one of the most common questions for those planning to enclose a terrace, balcony or pergola. Although with the OpenUp system, blinds are purchased in ready-made kits and not by the square metre, you can easily calculate the approximate price of the development to compare it with other offers on the market. In this guide, we show you how to calculate the price per square metre of external blinds (m2) yourself and plan your budget.

What does a square metre of external blinds mean?

A square metre of external blinds is an area measuring 100 cm wide and 100 cm high. In the OpenUp system, the bracket height, which determines the height of the entire development, is 58.2 cm. So if you install a board or slat that is 100 cm long, one such section will cover an area of 58.2 cm x 100 cm, or exactly 0.582 m².

How do I calculate the price per square metre of external blinds?

The price of the movable planks in the OpenUp system depends on the material used for the development. For the 2025 season, prices for sets with 100 cm long boards or fins are as follows:

• Set with pine board (100 cm): £229
• Set with unpainted aluminium fin (100 cm): £347.08

Each of these sets encloses an area 0,582 m².

To calculate the price per m² of external blinds, divide the price of the kit by the area it covers.

Calculation example for pine boards (100 cm)

• Set price: £229
• Installation area per set: 0.582 m²

229 zł / 0.582 m² = 393.47 zł/m²

Calculation example for unpainted aluminium lamellas (100 cm)

• Set price: £347.08
• Installation area per set: 0.582 m²

347.08 zł / 0.582 m² = 596.57 zł/m²

What is worth bearing in mind when comparing prices per square metre for external blinds?

A square metre of external blinds is always an area of 100 cm by 100 cm. In the OpenUp system, the calculation of the price per square metre is based on the price of the specific kit that encloses a specific part of this area. In the example, we are quoting kits with a board or slat length of 100 cm, which encloses 0.582 m². If you choose other lamella lengths, it is not the area per square metre that will change, but the price of building up that area. Longer boards or laths can mean fewer sections and fewer brackets needed for installation, which will affect the final cost per square metre of the development.

How do you calculate how many sets you need?

If you want to plan your built-in carefully, use our step-by-step instructions on how to divide the space into sections and select the right number of sets and boards. You will find practical examples and assembly diagrams. The manual is available via this link:
