Glass panels slide sideways on a horizontal track. When open they gather side by side on the track; glass that folds open is a separate mechanism.
Sliding glass panels move to the right or left on a horizontal track and, when open, gather on the track overlapping or side by side. The clear area left open is determined by the number of tracks and panels.
Glass that folds away to one side is a different system. In sliding glass the panels do not leave the track; when open, part of the glass still stands in front of the opening.
The panels slide on a horizontal track and pass in front of one another. As they gather on the track when open, part of the opening stays covered by glass.
Because the panels can be moved as far as you like, the amount of ventilation is adjustable. There is no need to open fully.
The glass and profile section are chosen for the span, the safety requirement and the selected model. Track and threshold type are chosen to suit the use.
From your measurements we compare sliding, folding and guillotine glass for the way you use the space.

In sliding glass the panels do not swing in or out like a hinged leaf; they slide on a horizontal track. When open the panels gather on the track and take up room there.
In sliding glass the panels stay on the track. In folding glass the panels travel along the track and form a stack at the side. We compare the two on the same opening, according to where you want the glass to sit when open.
The table below shows the components of the system and the options. Dimensions, loads and performance values depend on the selected model and the project; profile section and connection details are calculated separately for each project.
| Movement | Glass panels slide sideways on a horizontal track |
|---|---|
| Panels when open | They gather side by side on the track |
| Track system | Track and threshold type are chosen to suit the use |
| Glass and profile section | The glass and profile section are chosen for the span, the safety requirement and the selected model. |
| Profile colours | RAL colour options, wood-effect lamination |
| Feasible dimensions | Feasible dimensions are confirmed from your measurements and the structural design. |
| Wind load | Wind load is calculated from the project dimensions and the installation site. |
|---|---|
| Rain performance | The protection class of electrical components is stated for the selected model; the rain performance of the glass system is assessed separately. |
| Thermal performance | Thermal performance depends on the glass, profile and junction details being chosen together. |
| Opening direction | To the right, to the left or both ways; decided in the design |
| Lock and safety | Lock and safety hardware are determined by the selected model |
| Mounting | Wall or ceiling mounting, pergola integration |
| Warranty | Warranty scope and periods are stated per product and component in the written quotation and the warranty document. |
| Documents | The conformity and test documents that apply to the product are shared at the quotation stage. |

The three glass systems differ in how the panels move and where they sit when open.
| Feature | Sliding Glass | Folding Glass | Guillotine Glass |
|---|---|---|---|
| Movement | Slides sideways on a horizontal track | Travels on the track, stacks at the side | Moves vertically |
| Panels when open | Gather side by side on the track | Form a single stack of glass at the edge | Gather at the top or bottom depending on the model |
| Clear opening | Shown in the design from the number of tracks and panels | Shown in the design from panel count and stack space | Shown in the drawing from the project dimensions |
In all three systems the clear space left when open depends on the system and the project dimensions.
Sliding glass cannot be priced from a ready-made list; dimensions, glass, profile system and installation conditions differ on every project.

Panels travel along the track and turn to stack at the side. We show the space the parked panels take up in the project drawing.

In sliding glass the panels slide sideways on a horizontal track and gather on it. In guillotine glass the panels move vertically and gather at the top or bottom depending on the model. Which suits you depends on where you want the glass to sit when open.
Because the panels gather on the track, part of the opening stays covered by glass. The clear area left open is determined by the number of tracks and panels and is shown in the design.
Thermal performance depends on the glass, profile and junction details being chosen together. For heated use, the roof, glass, profiles, floor, airtightness and ventilation are assessed as a whole.
The number of panels is determined by the width of the opening and the track system. The exact number is calculated from the opening dimensions.
