Frameless. The glass is carried in an aluminium channel at each side, and nothing runs along the top, so there is no handrail on this balcony and nothing across the opening to look through.

The channel comes as aluminium. It can be powder coated to match the window frames or the render for an extra charge, if you would rather it did not read as bare metal against the house.

Why a frameless Juliet uses laminated glass

On a Juliet with a top rail, the rail is still there if a pane is damaged, so toughened glass on its own is normally accepted. Take the rail away and the glass is the whole barrier. It then has to stay in place after breakage rather than dropping out as granules, which means toughened and laminated rather than toughened alone. That is the thinking behind BS 6180, and it is why the glass on this balcony is thicker and dearer than on our railed designs.

Worth knowing, because it is not an upgrade we have bolted on. It is what a frameless balcony has to be. If the cost is the deciding factor, the honest answer is a railed design rather than a thinner frameless one, and the Wembley gets you a very similar clean run of glass with the fixings concealed inside a slotted rail.

What thickness of glass will I get?

13.5mm, 17.5mm or 21.5mm, decided by the width you order. A wider opening puts more load into the same two channels, so the glass steps up to suit it. You do not need to work that out yourself. Tell us the width and we specify the glass.

• Clear toughened and laminated safety glass, polished edges, radius corners
• Designed to the 0.74kN/m horizontal line load that applies to balconies and Juliet balconies
• Conforms to current UK building regulations for domestic applications. Tell us if it is going on a commercial property so we can advise accordingly
• UKCA marked, supplied with a Declaration of Performance

Side fixed or face fixed?

The channels click-lock and will go either into the reveal at the sides of the opening or onto the face of the wall. Which you choose is usually settled by what is around the opening: render, brickwork, a bay, a sill in the way. Some drilling on site is normally needed either way.

Say which way you are fixing when you order, because it changes the width of glass we cut. If you are not sure, send us a photograph of the opening and we will tell you which one suits it.

Does a Juliet balcony need planning permission?

Generally not, and that is the main practical reason people fit one instead of a walk-out. Balconies and raised platforms are not permitted development, but a Juliet balcony with no external platform is one of the recognised exceptions, because there is nothing to stand on and nothing new to overlook from. Conservation areas and listed buildings are a separate conversation, so check with your planning department if either applies to you.

Do I need building regulations approval?

Guarding an opening at first floor level is exactly what this balcony is doing, so building control will usually have an interest in it. The heights and the loadings are set out in plain English in our balcony and Juliet balcony building regulations guide.

We will make it to whatever specification your project requires, and regularly do. What we will not do is decide on your behalf what your building has to comply with. We are a fabricator, not your building control body, and confirming what is required is a job for your building control officer or your design team.

Not the size in the list?

The widths above are the everyday ones rather than the limit of what we make. Everything leaves the factory made to order anyway, so an odd size is not a special favour and it does not usually cost dramatically more. Complexity drives the price, not bespokeness. Call 0114 243 9009 or email sales@diometonline.co.uk with the width and we will price it.
