Caerphilly: glass stair balustrade
Toughened glass can occasionally break without impact because of tiny nickel sulphide inclusions. Heat soak testing to BS EN 14179 reduces that risk by breaking flawed panels in the factory, but it does not remove it entirely, which is one more reason laminated glass is used in guarding.
The interlayer inside laminated glass decides how a broken panel behaves. Standard PVB holds the fragments together but can let a fully broken panel sag, while stiffer structural interlayers help it stay upright. The right choice depends on whether a handrail is fitted and how exposed the balustrade is.
BS 6180, the code of practice for barriers, says a handrail should be used where glass guards a drop of more than 600mm, unless the glass is laminated toughened glass that would stay in place if a panel failed. That is why frameless balustrades without a top rail use laminated glass.
Toughened glass cannot be cut, drilled or shaped once it has been toughened, so every hole, notch and corner is made before processing. That is why we template on site and order each panel to exact sizes. A panel made to the wrong measurement has to be remade, not trimmed.

- Coast
- Caerphilly sits roughly 11 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. Salt air attacks lower-grade metal fittings and leaves deposits on glass, so balustrades near the coast need hardware and finishes suited to marine exposure, well-drained channels and regular rinsing. Strong onshore wind on exposed balconies also affects the glass and fixing specification.
- Daylight and sun
- In Caerphilly the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Glass guarding on a sunny balcony brings in heat and glare as well as the view. Tinted or satin glass can soften low winter sun on a terrace, while low-iron glass keeps colours true on north-facing spaces where every bit of daylight counts.
- Access and setting
- Older rural homes often have uneven floors, timber structures and stone walls, all of which affect how channels and posts are fixed. Exposed decks and hillside terraces also face strong wind, so the glass and fixing system are chosen for that exposure.
- Rules in Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

Welsh building regulations set minimum guarding heights for stairs, landings and balconies, and glass guarding must be designed to resist the required loads.
Choosing your glass balustrades
Frameless channel system
Laminated toughened glass held in a continuous floor channel, giving a clean edge with no posts. Suits balconies, terraces, decks and modern stairs.
Post and clamp
Glass panels clamped between stainless steel or powder-coated posts. Often uses thinner glass and suits long runs, decking and simpler budgets.
Low-iron glass
Glass with less iron, which removes the green tint seen on the edges of standard glass, most noticeable in thick laminated panels.
Glass Balustrades in Caerphilly: questions
How thick does the glass in a balustrade need to be?
Glass thickness depends on the fixing system, the panel height and the load the barrier must resist, so there is no single answer. Frameless channel systems commonly use thick laminated toughened glass, such as 21.5mm, while post and clamp systems often use thinner glass. The system maker's tested data sets the minimum, and we specify from that.
What happens if a balustrade panel breaks?
With laminated glass, the broken panel is held together by its interlayer and should stay in place until it is replaced. With toughened-only glass, the panel breaks into small pieces and the handrail becomes the barrier. Either way, keep people away from the edge and contact us so we can make the area safe and remake the panel to size.
Do glass balustrades need a handrail?
Not always. Under BS 6180, a handrail should be used where the glass guards a drop of more than 600mm, unless laminated toughened glass is used that would stay in place if a panel broke. Frameless systems without a top rail therefore use laminated glass, while toughened-only glass needs a handrail tied across the panels. We confirm which applies to your job at survey.
What affects the cost of a glass balustrade?
The main cost drivers are the length of the run, the number of panels and corners, the glass thickness and interlayer, and the fixing system. A top handrail, low-iron or tinted glass, special hardware finishes and difficult access all add to the price. See the guide prices for typical ranges, and your written quote fixes the price for the specification shown.
