Key points
- Tempered glass with no vertical frames — continuous views, full accordion opening.
- Protect from wind, dust and noise without losing natural light.
- Ideal for terraces, penthouses, porches, balconies and hospitality.
- Low maintenance and reversible (helpful for community approval).
What they are and how they work
Quick answer
A frameless glass curtain is a set of tempered-glass panels that slide and fold sideways (accordion) along a top and bottom track, with no vertical mullions between panels. Closed, it shelters the terrace; open, it frees it completely.
Unlike a framed aluminium enclosure, frameless glass curtains have no vertical posts, so the view of the sea or mountains reads as one continuous pane. That is why they dominate penthouses and front-line properties on the coast.
Benefits in the coastal climate
- Panoramic views with no vertical interruptions.
- Protection from the Levante wind, dust and light rain.
- Better acoustic and thermal comfort than an open terrace.
- Flexible opening: fully open in summer, closed in winter.
- Easy cleaning and low maintenance, including the outside from within.
Glass options and limits
Panels use safety-tempered glass in various thicknesses depending on size and exposure. It can be clear, solar-control (to cut heat) or satin-finished for privacy. The trade-off versus an aluminium enclosure is thermal insulation: glass curtains greatly improve comfort but are not a fully sealed, double-glazed room.

Permits and community of owners
Because the enclosure affects the building façade, you normally need the community of owners' authorisation, and possibly a municipal notification. As the system is removable, it tends to fit well — but always confirm with your community and town hall before installing.
Frequently asked questions
Do glass curtains keep out the cold?
They greatly improve comfort versus an open terrace and cut draughts, wind and noise. For maximum thermal insulation, an aluminium enclosure with a thermal break and double glazing performs better, at the cost of visual lightness.
Can they open completely?
Yes. The panels fold accordion-style to one or both sides, freeing almost the entire opening so you regain an open-air terrace in summer.
Do they resist coastal wind?
Yes, they are specified with the right glass thickness and hardware for each terrace's exposure. In very windy locations the system calculation is adjusted.
