Buyer's guide: glass curtains (cortinas de cristal)
Glass curtains are frameless panels of toughened glass that run along a track at the top and bottom. Each panel slides along and then swings open, so the whole terrace can be opened up and the panels stacked neatly to one side. Closed, they keep out wind, rain and dust without blocking the view.
Ask about the glass thickness (8 mm and 10 mm toughened glass are common), the quality of the tracks and bearings, and how the bottom track drains. Glass curtains aren't airtight and don't insulate like double-glazed windows, so they suit shelter and extra living space rather than a fully heated room.
On high or exposed terraces, ask how the system copes with wind and whether it has locks and child-safe handles. Blinds made for glass curtains can be added for shade. In apartment blocks, check what your community of owners allows before you order.
Questions to ask before you sign
- What glass thickness is used, and is it toughened?
- How does the bottom track drain?
- How do the panels lock, and are the handles child-safe?
- Is the system suitable for the wind on my terrace?
- Can blinds be added later?
- What does the warranty cover on tracks and bearings?
Common questions
Do glass curtains insulate?
Not like windows. They block wind and rain and make a terrace much more usable in winter, but there are small gaps between panels, so they are not airtight. If you want a heated room, ask about a framed enclosure instead.
How thick is the glass in a glass curtain?
Most systems use 8 mm or 10 mm toughened safety glass. Thicker glass is heavier and stiffer, which matters on wide or exposed openings. Ask the company which thickness it recommends for your terrace.
Can glass curtains be opened completely?
Yes. The panels slide to one end of the track and swing open, so the terrace can be fully opened in summer. Ask how much space the stacked panels take up.
