Question 1

What is a cero sliding window?

Accepted Answer

cero is Solarlux's minimal sliding window family. Enormous glass panes with profile sight lines measured in millimetres turn an elevation into glass, blurring the boundary between inside and outside rather than framing it.

Question 2

How slim are the sight lines on cero systems?

Accepted Answer

The profile sight lines are measured in millimetres and the glass surface reaches up to 98% of the elevation, which is why cero suits projects where the architecture, not the frame, should do the talking.

Question 3

How large can cero panels be?

Accepted Answer

Panels up to 15 m2 and weights up to 1,000 kg. Sizes that large are only practical because of the lift-and-slide engineering, which takes the weight off the seal as the panel moves.

Question 4

Which cero systems are available?

Accepted Answer

cero II, cero III and cero IV, covering sliding windows and doors, fixed glazing and combinations of both, with multiple tracks so panels can slide past one another and park clear of the opening.

Question 5

What glass can be used with cero?

Accepted Answer

Large-format toughened or laminated safety glass, with heat-soak testing, solar control and acoustic builds available. The glazing is what carries the performance, so we specify it against the orientation and the room's use.

Question 6

Do cero systems have flush thresholds?

Accepted Answer

Yes. Flush and accessible thresholds are available so the floor runs uninterrupted to the glass, with drainage designed into the track rather than a step.

Question 7

Where is cero usually used?

Accepted Answer

Living spaces, wintergardens, pool halls and panoramic facades, on both residential and commercial projects, wherever the client wants the maximum glass with the minimum frame.

Question 8

How do such heavy cero panels move so easily?

Accepted Answer

The panels run on stainless steel carriages and the lift-and-slide action raises the panel onto its rollers as you turn the handle, so a 1,000 kg panel still moves with one hand and seals again when it closes.

Question 9

How do cero systems perform thermally and acoustically?

Accepted Answer

Depends on the build specified. The thermally broken versions take double or triple glazing for high thermal performance, and the acoustic performance comes from the glass build, which we match to the noise level at your site.

Question 10

Can you help me specify cero for a tender?

Accepted Answer

Yes. We issue the technical data, drawings and DWG files, and the MFP Specifier on our Specifications page builds a clause you can drop into your specification. Send us the drawings and we will reply within 24 hours.
