How to choose a glass enclosure system for your terrace
Sliding, pivoting or guillotine? Each system has its strengths. Here is how to choose based on your space, budget and how you intend to use the terrace.

In short
Choose sliding for thermal and acoustic insulation, pivoting if you want the terrace fully open in summer, and guillotine for the cleanest look. The decision starts with an on-site survey, because the width of the opening and the existing structure usually rule one option out.
A glass-enclosed terrace is not only weather protection — it is an extra room, usable all year, without losing the light or the view. Which system fits depends on a handful of factors worth understanding up front.
The sliding system
Toughened glass panels slide sideways on tracks, in thermally broken aluminium frames. This is the best option for thermal and acoustic insulation, and the one to pick if you want to use the terrace through the cold months.
The pivoting system
Panels slide the full length and then pivot, freeing the whole surface when you want the terrace fully open. They can be parked left or right depending on how the space is arranged.
The guillotine system
Panels rise and drop vertically with no visible side frames. It doubles as an insulating wall or a balustrade and gives the cleanest possible look, which is why it turns up so often on restaurant and hotel terraces.
