Juliet balcony in front of a full-height window

Juliet balcony

A balustrade fitted in front of the window: full-height opening, safety without a balcony.

The product

The balcony that does not project

An opening at full height, with no slab to pour and no floor area to declare.

Swiss Made glazing: made in Switzerland by our partner glassmaker, installed by our own teams.

A Juliet balcony sits in front of the opening and turns a window into a full-height one. There is no floor: the projection runs from a few centimetres to twenty or thirty, and you put neither table nor chair on it. What you are buying is not floor area — it is light, air, and a view that reaches the ground.

The system comes down to two posts taken on the frame, in the reveal or on the masonry, joined by a laminated glass panel that slides in and clips home. It works with uPVC, aluminium and timber windows, sits behind roller-shutter guide rails, and includes its own drainage: water passing between glass and frame exits through the channel instead of standing on the sill.

In Switzerland this product lives mainly in refurbishment: the windows of a building are replaced, and the opportunity is taken to open down to floor level. The question that decides everything is load transfer. A uPVC frame alone almost never takes the load: you have to reach the steel reinforcement in the frame or the masonry behind, and the survey settles it, with probing.

Depending on the situation, the glass is fitted from inside. On a building façade that changes the whole economics of the job: no scaffolding, no platform, no permit to occupy public space. We survey each reveal one by one — in refurbishment none of them is square and the widths vary from floor to floor.

  • Two posts only: the opening stays clear across its full width
  • Mounted on the frame, in the reveal or on masonry, including behind a roller shutter
  • Can be fitted from inside: no scaffolding or platform on a building façade
  • Drainage built into the channel — no standing water behind the glass
  • Six stock heights from 500 to 1200 mm, RAL colours

Choosing your kit

The load column is empty, and that is not an oversight: on these kits, capacity is not read in kN/m but in the intersection of width × height × glass thickness.

The loads shown are those the system is approved for. Final sizing depends on the use of the space and the wind pressure at the site — that is what we check during the survey.

Swiss compliance

What SIA requires, what the system carries

The load quoted on a product sheet is the one the system has been tested to carry. SIA 261 sets what Switzerland requires according to the use of the space. The two scales do not line up — here is the comparison, done for you.

SIA 261 — horizontal load, measured at 1.20 m at most

Dwellings, offices, retail
0,8 kN/m

Residential balcony and terrace, loggia, office, retail floor, storage, car park

Assembly areas

Assembly with crowd movement
3,0 kN/m

Figures taken from the technical brochure of the Swiss Council for Accident Prevention, which summarises SIA 261 and SIA 358. They frame the choice; they do not replace the engineer's verification, which we ask for as soon as the element falls outside the ordinary case. Final sizing happens at the survey.

Finish

Matching the window

A Juliet balcony is always seen next to the window frame: it is the only range where the colour is not a free choice but a match. So you start from the existing window, not from a colour chart. In Swiss refurbishment RAL 7016 anthracite comes back most often, followed by RAL 9016 white on buildings from the 1990s.

Allow for the coating lead time: on a stairwell with twenty openings, one properly surveyed order beats catching up colour by colour.

Frequently asked questions

About juliet balcony

01What glass thickness for a Juliet balcony?

The system is ordered in two glass-thickness ranges, and only two: 10.76 – 12.76 mm and 17.52 – 21.52 mm, in toughened laminated glass. The width and height of the glazing decide the range, on the manufacturer's sizing table; we set it at the survey, never by estimate.

02What height should be allowed?

Kits exist in 500, 700, 900, 1000, 1100 and 1200 mm. The usable height is measured from the finished internal floor, not from the sill: 1.00 m minimum, 1.10 m as soon as the fall height exceeds 12 m. On a floor raised afterwards by a floating screed, that is the mistake that comes back most often.

03Can it be fitted to a uPVC window?

Yes, the system is compatible with uPVC, aluminium and timber. But the load is not transferred by the uPVC profile alone: you reach the steel reinforcement in the frame or the masonry. We probe the frame at survey — a balustrade screwed into hollow uPVC is work that will not hold.

04And behind a roller shutter?

That is provided for: the posts slide behind the guide rails and the rail stays removable. You need to know before ordering, because it changes the mounting variant and the anchor point.

05Is scaffolding needed?

Not necessarily. Depending on the configuration the glass is fitted from inside, which removes the scaffolding, the platform and the occupation permit. On a four-storey building that often deletes the heaviest item in the quote.

06Does the channel drain water away?

Yes, drainage is built in. Under our climate that is decisive: water standing behind the glass freezes, and frost works on both glass and fixing. On work without drainage, the damage appears in the third or fourth winter.

07Which glass if the view overlooks a neighbour?

A laminated panel with an opal interlayer, or acid-etched glass, keeps the light while cutting the view. The trade-off is known: etched glass shows water and finger marks, opal does not. On a north façade opal darkens little; facing south it actually adds comfort.

08Must a Juliet balcony be laminated?

Yes, without exception. The sizing tables are established for toughened laminated glass: it is the interlayer that holds the pieces in the event of breakage, and twelve metres above a pavement that property is not negotiable.

09What does a Juliet balcony cost?

As an order of magnitude, 600 to 1500 CHF per opening supplied, depending on width, glass thickness and finish. Installation is quoted after survey, and any strengthening of the spandrel or masonry is priced separately: it is the item that varies most from one building to another.

10Are the systems certified?

The systems we install are certified, backed by test reports and approvals. We attach the documents for the chosen variant to the quote — useful when the managing agent or the owners' association has to assemble a file.
