Stand-off Juliet Balcony

​A stand-off Juliet balcony provides effective fall protection across full-height windows or French doors while maintaining a clean, modern appearance. Instead of using posts or channels, the glass is face-fixed using stainless steel stand-off pins, creating a minimalist design with maximum light and visibility.

At Fusion Glass Ltd, we supply bespoke drilled laminated glass panels and high-quality stainless steel stand-off fixings, specifically suited to Juliet balcony installations.

 

Before You Start

Juliet balconies act as fall-protection systems, so careful planning and correct fixing into the structure are essential.

Before installation:

• Ensure the surrounding structure is structurally sound (masonry, concrete, steel, or reinforced timber)

• Confirm there is sufficient space either side of the opening for stand-off fixings

• Use appropriate PPE at all times

• Glass panels should always be handled by a minimum of two people

For timber constructions, additional structural support behind the fixing face may be required.

 

Glass Thickness & Size Guide (Important)

The required glass thickness depends on the overall width of the Juliet balcony:

• Up to 1700mm wide: 17.5mm toughened laminated glass

• 1800mm – 3000mm wide: 21.5mm toughened laminated glass

• 3000mm – 3750mm wide: 25.5mm toughened laminated glass

 

Ordering Note

Stand-off Juliet balconies require 200mm of fixing space on each side of the window.

When ordering, take your clear opening size (wall-to-wall) and add 400mm to determine the total glass width required.

This ensures adequate room for the stand-off fixings and correct load transfer.

 

Tools & Equipment Required

Typical tools required include:

• Tape measure and marker

• Spirit level

• Impact drill and cordless drill

• Drill bits suitable for masonry, timber, or steel

• Metric Allen keys / hex bits

• Stand-off spanner

• Masking tape (for set-out)

• Suction cups for glass handling

• Glass cleaner and soft cloth

 

Step 1: Set Out the Balcony Position

Clean the fixing surface and mark the centre line of the opening.

Using masking tape, mark:

• The left and right extents of the glass (including fixing allowance)

• The vertical positions of the stand-off fixings

Accurate set-out at this stage ensures the glass sits centrally across the opening with even fixing spacing.

 

Step 2: Drill Fixing Holes

Drill fixing holes according to the substrate:

• Concrete / masonry: Drill to suit M10 anchors or chemical fixings

• Steel: Drill clearance holes for M10 bolts or threaded rod

• Timber: Drill pilot holes into solid structural backing

All holes must be drilled square and level to ensure the stand-off bodies sit flush.

 

Step 3: Prepare and Install the Stand-Off Bodies

Stand-off fixings are supplied pre-assembled and should be separated before fitting.

1. Fix the stand-off bodies securely to the structure using appropriate fixings

2. Ensure the correct thread depth is engaged into each stand-off body

3. Check alignment and spacing before proceeding

Once installed, all stand-offs should sit flat and aligned vertically.

 

Step 4: Prepare for Glass Installation

Fit the required washers, bushes, and protective gaskets onto each stand-off stud.

Ensure all contact surfaces are clean to prevent debris being trapped behind the glass.

 

Step 5: Install the Glass Panel

With at least two installers:

1. Carefully lift the glass panel into position using suction cups

2. Guide the drilled holes over the stand-off studs

3. Check the glass is centred, level, and plumb

The drilled holes allow for small adjustments before final tightening.

 

Step 6: Secure and Align the Glass

Once the glass is correctly positioned:

• Fit the decorative stand-off caps

• Tighten caps gradually using the stand-off spanner

• Re-check alignment and spacing before fully tightening

Work evenly across all fixings to avoid stressing the glass.

 

Step 7: Final Checks and Cleaning

Once installation is complete:

• Ensure all fixings are fully tightened

• Check the glass is secure with no movement

• Remove any protective tape or packaging

• Clean the glass with a mild glass cleaner and soft cloth
