Hertfordshire: curtain wall glass replacement
Toughened glass can very occasionally break on its own because of nickel sulphide inclusions. Heat soak testing to BS EN 14179 reduces that risk by breaking flawed panes in the factory, and it is often specified for toughened glass high on facades where a breakage is harder to deal with.
BS EN 13830 is the product standard for curtain walling. It treats the system as a kit, including its fixings, set from vertical up to 15 degrees off vertical. Sloping roof glazing and patent glazing fall outside it and are covered by other standards.
Where a glazed screen must resist fire, the glass only performs as part of a fire-resistant system tested with its frame, seals, beads and fixings. Ratings use letters such as E for integrity and EI for integrity and insulation, and components must not be swapped without test evidence.
Under the energy rules for new work in England, curtain walling performance is assessed for the whole system, including frames and opaque infill panels, not just the glass. Solar gain through the glass is also considered, so the glass choice balances heat loss, overheating and daylight.

What applies in Hertfordshire
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
If the glass sits in a fire-resisting door or screen, such as a flat entrance door or a commercial corridor screen, it must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.
Hertfordshire is inland, around 39 km from the nearest coast at its closest point, so salt exposure is rarely a factor.
Commercial buildings on open rural or upland sites can face high wind exposure and driving rain, which affect frame sizes, glass thickness and sealing details. Longer delivery routes for large glass units also need planning in advance.

Choosing your curtain walling
Structural silicone glazing
Glass bonded to carrier frames with structural sealant, giving a flush external face with minimal visible framing.
Integrated opening vents
Top-hung or parallel-opening vents built into the curtain wall grid to provide natural ventilation without breaking the facade line.
Stick curtain wall
Mullions and transoms assembled on site with glass and panels fitted afterwards, suited to low-rise buildings, entrances and ground-floor screens.
Unitised curtain wall
Factory-assembled, pre-glazed storey-height panels lifted into place, reducing site joints and work at height on taller or tight sites.
Curtain Walling in Hertfordshire: questions
What is the difference between curtain walling and windows?
Curtain walling is a continuous framed wall of glass and panels that spans across floors and hangs off the building structure, carrying its own weight and wind loads. Windows sit within individual openings in a masonry or framed wall. Curtain walling suits large glazed areas and multi-storey facades, while windows suit punched openings.
How does curtain walling keep water out?
Curtain walling uses outer gaskets and seals to shed most rain, with drainage routes inside the framing that collect any water getting past them and lead it back outside. Inner seals then provide the air seal. Keeping drainage outlets clear and gaskets in good condition is essential, because blocked drains or shrunk seals can let water into the building.
Can a single broken glass unit in a curtain wall be replaced?
Usually, yes. In capped systems the cap and pressure plate are removed to release the glass, and a new unit is fitted and resealed. Structurally bonded glass needs the new unit bonding to its carrier, which takes more preparation. Height and access drive much of the work, so we survey the unit and access before quoting.
Do glazed screens in offices and entrances need markings?
Large areas of clear glass that people could walk into need to be made visible. In England, the guidance for buildings other than dwellings puts manifestation at 850–1000mm and 1400–1600mm above the floor, and workplace rules across Great Britain require glass to be marked where needed for safety. Frosted bands or logos can meet this.
