Everything about glass enclosures

Glass Curtains FAQ

Do glass curtains insulate from the cold?

Yes, they significantly reduce cold and wind ingress. They are not as airtight as a window, but they allow comfortable terrace use in winter.

The tempered glass panels meet safety standards (as per UNE-EN 12150-1 and CTE DB-SUA — safety against impact risk; UNE-EN 12150).

How much do glass curtains cost?

The price depends on the opening size and number of leaves. A standard 3 linear metre enclosure starts from €2,200.

Request a personalised quote. Panels are manufactured with 10mm tempered safety glass (certified to UNE-EN 12150-1, as per UNE-EN 12150) for maximum safety.

Do they need maintenance?

Very little. Lubricate the rollers every 6-12 months and clean the glass.

There are no profiles to paint or seals to replace.

Can they be installed on any terrace?

Yes, they adapt to virtually any terrace or porch. They can also be installed under pergolas and existing enclosures.

All installations comply with energy efficiency building regulations (as per CTE DB-HE — energy saving) and safety glazing requirements (CTE DB-SUA).
