What glass is used for balconies?

Balconies typically use laminated glass — two panels bonded with a PVB or EVA interlayer. If broken, the interlayer holds the glass together rather than allowing shards to fall. Most frameless channel balcony systems use 17.5mm or 21.5mm laminated glass. Framed post-and-rail systems may use toughened glass where the panels are fully supported.

What is the minimum guarding height for a glass balcony?

BS6180 and Approved Document K specify minimum guarding heights based on height above ground and use. Residential balconies above 600mm from ground level typically require 1100mm guarding. Commercial installations may require higher. We specify and document compliance as part of every balcony installation.

What is the difference between a balcony and a Juliet balcony?

A glass balcony is a projecting platform — it extends from the building and provides a usable outdoor area. A Juliet balcony is a fixed glass barrier mounted flush to the wall across a door opening — it provides no standing space. If you want to step outside, you need a projecting balcony.

Balcony vs Juliet Balcony — Which Do You Need?

A glass balcony is a projecting platform you can step out onto — it has a structural floor and a guarding balustrade around the edge. A Juliet balcony is a fixed glass barrier across a door opening with no standing space. If you want to step outside, you need a projecting balcony.

Adding a projecting balcony is a structural project — the floor needs engineering and the balustrade is rated to the commercial loading standard of 3.0kN/m. We handle the balustrade and glazing; if you're creating the structure from scratch, we can advise on build sequence and work alongside your structural contractor.

Style 01

Frameless Channel Glass Balcony

The premium frameless option. Glass panels slot into a continuous aluminium base channel fixed to the balcony structure — with no posts, no clamps, and no visible fixings. The result is an completely uninterrupted panoramic view that makes this system the top choice for high-end residential properties and apartments.

Continuous aluminium channel base fixing
No posts or clamps — unobstructed views
Toughened or laminated glass panels
Optional stainless steel or glass handrail
Straight, L-shape, and U-shape configurations

Style 02

Frameless Spigot Glass Balcony

Glass panels are supported on minimalist stainless steel spigots bolted to the balcony structure. The elevated fixing point allows surface water to drain freely beneath the glass — making spigot systems particularly popular on raised decking, roof terraces, and tiled balcony surfaces. A modern, open look with excellent weather performance.

Stainless steel spigot fixings
Excellent drainage — no water pooling under glass
Frameless, contemporary appearance
Top-fix and side-fix spigot options
Optional handrail for comfort and compliance

Style 03

Stainless Steel Framed Glass Balcony

A full stainless steel post-and-rail frame with glass infill panels. This system delivers excellent structural integrity, a strong architectural presence, and long-term durability in exposed external conditions. The defined frame adds a bold design statement — popular in commercial settings, modern apartment developments, and properties where longevity takes priority.

Full stainless steel frame — posts, rails, handrail
Toughened glass infill panels
Brushed or polished stainless steel finish
Excellent weathering and corrosion resistance
Commercial and residential rated options

Configuration Options

Available Shapes & Configurations

All balcony systems are available in straight, L-shape, and U-shape configurations — manufactured to your exact balcony dimensions.

Straight

Single frontal run — standard for most projecting balconies.

L-Shape

Front and one side — suits corner balconies and wrap-around terraces.

U-Shape

Front and both sides — full perimeter guarding for larger terraces.

Glass Specification for Balconies

Glass balconies are governed by BS6180, which sets the minimum barrier loading and guarding height requirements. The glass specification depends on the system, the panel span, and whether there is a risk of material falling to a level below:

Toughened Glass

Heat-treated to be approximately four to five times stronger than standard float glass. Breaks into small granular pieces rather than sharp shards. Used in framed systems where the glass is supported on all sides or at the base and posts.

Laminated Glass

Two or more glass panels bonded with a PVB or EVA interlayer. If broken, the interlayer holds the glass together — required on balconies above occupied areas, Juliet balconies, and anywhere falling glass presents a risk. Most channel balcony systems use 17.5mm or 21.5mm laminated glass.

Guarding Heights

BS6180 and Approved Document K specify minimum guarding heights based on height above ground and use. Residential balconies above 600mm typically require 1100mm guarding. Commercial installations may require higher. We specify and document compliance as part of every balcony installation.

Commercial Loading (3.0kN/m)

Commercial-rated balustrades must resist a horizontal line load of 3.0kN/m — higher than the 0.74kN/m residential requirement. Balconies on apartments, HMOs, and commercial buildings are subject to the commercial loading standard. We can supply compliance documentation for Building Control where required.

Frequently Asked Questions

Yes. Glass balconies are designed with safety as the primary consideration. We use toughened or laminated safety glass, which is highly resistant to breakage. All installations comply with UK Building Regulations and BS6180, specifying minimum guarding heights and structural performance requirements.

Glass balconies are fully engineered for outdoor use. Panels are toughened or laminated for strength and UV resistance. All hardware is specified for external conditions — stainless steel and aluminium components resist corrosion in the UK climate.

Yes. Glass panels can be supplied in a range of tints (grey, bronze, blue) or with a frosted or satin finish where additional privacy is required. We can advise on the best option for your situation.

Minimal. Regular cleaning with a mild detergent and water keeps glass looking its best. Periodic inspection of fixings and hardware — typically annually — ensures everything remains in good order. Stainless steel components may benefit from an occasional wipe with a stainless steel cleaner.

This depends on your property type and location. Balconies on existing buildings often require planning permission as they can affect the appearance of the property and overlook neighbouring land. We recommend checking with your local planning authority before proceeding.
