The system
For elevations that don't stand upright.
Slope lets a Sky-Frame sliding window sit at an angle — projecting out from the facade or leaning into the room, by up to 20°. The bearing assembly carries the vertical and horizontal loads that an inclined pane puts on it, so it still runs the way a vertical one does.
The drainage meets driving-rain requirements whichever way the glass leans. Slope is resolved project by project — send us the section and we'll come back with what's achievable.
Specify Slope when
- The elevation leans, and the glazing has to follow it rather than step back from it.
- You want the glass to project out from the facade, or lean into the room.
- The inclination is within 20°.
Technical
Key figures
From Working with Sky-Frame. Sky-Frame publishes fewer standard figures for Slope than for the straight systems — we confirm sizes and performance per project.
| Property | Value | Note |
|---|---|---|
| Inclination | up to 20° | Inwards or outwards |
| Loads | Vertical + horizontal | Taken by the bearing assembly |
| Drainage | Driving-rain compliant | In either direction of incline |
Brochures are hosted by Sky-Frame. CAD drawings and technical documentation need a free Sky-Frame registration.
Slope in use


The other three systems
Classic
The original Sky-Frame system. Straight runs, ceiling-height glass, frames flush with floor and ceiling.
Panes to 2.3 × 4 mArc
Curved glass on a curved track, for radiused elevations.
Radius from 2.5 mPivot
A glass door that turns on an offset axis. One leaf, up to 2.5 × 4.5 m.
Leaf to 2.5 × 4.5 mFor architects
Not sure Slope is the right call?
Send the elevation and we'll say so either way. We'd rather talk you into a simpler system than sell you one you don't need.
