How much does it cost to enclose a terrace with glass curtains? Guide prices per m²

As a guide, enclosing a terrace with glass curtains in Spain costs between €200 and €450 per square metre installed; a basic sliding aluminium enclosure is around €250-400/m² and a bioclimatic pergola €400-900/m². The final price depends on the size, the glass thickness, the opening system and how easy the site is to access, which is why only a quote based on real measurements gives you the exact figure.

Enclosing a terrace in a block of flats: permissions, majorities and tips

To enclose a terrace in a block of flats you need the agreement of the owners' meeting: Spain's Horizontal Property Act requires a vote in favour from three fifths of the owners, who must also represent three fifths of the ownership shares. Even if only you use the terrace, the façade is a common element, so the enclosure must respect the look of the building and also needs council approval.

Your questions answered

What is best for enclosing a terrace: glass curtains, a pergola or a roof?

To enclose a terrace, glass curtains are the best option if your problem is wind, rain or noise, while a bioclimatic pergola or a retractable or fixed roof is the answer if what you need is shade or cover from the rain. If you want an extra room you can use all year round, the ideal is to combine a roof or pergola with glass curtains on the sides. During the free site visit we'll recommend the option that best suits your terrace.

Do you work for residential buildings and hospitality, or only for homes?

As well as homes, we install glass enclosures, pergolas and roofs for residential buildings, bars, restaurants and hotels across the province of Cádiz. In blocks of flats it is common to approve a single enclosure model for the whole façade, and we provide the technical description for you to present at the owners' meeting. Find out more about enclosures for restaurant and bar terraces and how to enclose a terrace in a block of flats.

What maintenance do glass curtains and pergolas need near the sea?

Glass curtains and pergolas need little maintenance, even near the sea. Clean the curtains with water and an ordinary glass cleaner, and keep the tracks clear of the sand blown in by the levante wind. For bioclimatic pergolas, cleaning the louvres and gutters with water and mild soap a couple of times a year is enough. On the Cádiz coast, rinse off the salt with fresh water more often and, if the system is motorised, have the motor checked regularly.

How long does it take to install a glass enclosure or a pergola?

Once you accept the quote, it is usually installed within 2 to 4 weeks, depending on the system and finishes you choose. First we visit, measure and give you a written quote; then we make everything to measure and our team installs it, cleans up and shows you how it works. We work in El Puerto de Santa María, Jerez, Cádiz and the rest of the province: see all the areas where we install.

Is the quote free and with no obligation?

Yes. The site visit, measuring and quote are free and with no obligation anywhere in the province of Cádiz. Call us, message us on WhatsApp or fill in the form and we'll get back to you within 24 working hours.

Do you handle grants for window replacement?

Yes. Replacing your windows with energy-efficient frames can be deducted up to 40% from your Spanish income tax (IRPF), under the energy-efficiency improvement deduction available until 31/12/2026, and, depending on the call for applications, may qualify for regional (Junta de Andalucía) or national grants. We advise you and prepare the energy certificate and the paperwork.
