Canopy

1000 mm in 17.52 mm with an SGP interlayer, 1100 mm in 21.52 mm in PVB as in SGP, and 1200 mm in 21.52 mm SGP provided the panel is at least 1590 mm wide. The fixing is one-sided in all three cases: nothing runs diagonally down the façade.

3000 mm. Beyond that, several modules are chained with an expansion joint between them — aluminium moves, and a six-metre canopy installed with no clearance distorts in its first summer.

Yes, and it is the first check. In Switzerland the snow load is taken to SIA 261: it depends on the altitude and topography of the site. A 1200 mm projection in Nyon and the same in Verbier are not sized the same way, and it is that calculation which settles the glass build-up — not the other way round.

So the water leaves instead of standing. A horizontal pane keeps a film of water that dries out leaving limescale, and in winter that film freezes. The 10° belong to the system: they cannot be adjusted, so the fixing dimension at the lintel has to be right first time.

As a sheet, at the leading edge. The point of fall moves with the projection: a 1200 mm canopy does not wet the same place as a 1000 mm one. If the threshold is finished in pale stone or timber, that is decided at survey and not after the first storm.

Concrete, concrete with external insulation, steel and timber. Each case has its anchor kit. Insulated concrete is the most delicate — you have to cross the insulation without creating a cold bridge or crushing the board — and timber requires checking the real load-bearing section, not the one on the drawing.

Only the lower pane of the laminate is drilled, in the factory. That prevents any misalignment between the layers. Laminated glass is neither drilled nor recut on site: if it is not right, it goes back.

Rarely. Installation is carried out from the user's side, so a working platform is enough for most villa entrances. On a high-level building entrance, it is the access platform that determines the installation price far more than the product itself.

The interlayer. SGP is markedly stiffer than PVB: at equal glass thickness it allows a greater projection and a smaller deflection. That is why the 1200 mm projection only exists in SGP.

The price is set after survey, in CHF, and it moves on four points: projection and width, the substrate to be drilled, the working height, and the finish chosen. An anodised 1.4 m canopy on bare concrete and the same one coated outside the chart on insulated concrete are not the same job. We do not give a range before we have seen the lintel.

The glass, like a window. The aluminium, with soapy water and a soft cloth twice a year — that is also a condition of the warranty. While you are there, check that the drainage holes in the channel are not blocked with needles or leaves.

The systems we install are certified and covered by a technical approval. We attach to the quote the test reports for the chosen build-up, projection and thickness included.
