Glazed facade systems in Ballymoney
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.
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.
Building regulations require external walls to limit the spread of fire, so curtain walling design has to consider how its materials react to fire and how fire could pass between floors. The requirements depend on the building's height and use, and differ between the UK nations.
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.
What a typical job includes

- BT53 and the surrounding area, including Coleraine, Portstewart and Ballymena
- Coast
- Ballymoney sits roughly 17 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. Facades near the sea face salt-laden wind and driving rain, which attack frame finishes and stress seals. Suitable coating specifications, regular washing, gasket checks and higher design wind loads for exposed sites all matter for curtain walling there.
- Daylight and sun
- In Ballymoney the midwinter sun reaches about 12° above the horizon at noon, with roughly 6.9 hours of daylight, rising to about 58° and 17.1 hours in midsummer. Large glazed facades bring in plenty of daylight but also solar gain and glare, especially on south and west elevations. Solar control glass, shading and blinds are balanced against light transmission so interiors stay bright without overheating.
- Access and setting
- 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.

Glass clamped by pressure plates behind a visible external cap, available in different profiles and colours to emphasise the grid.
Curtain Walling in Ballymoney: questions
Does new curtain walling need building regulations approval?
New curtain walling is building work that has to meet requirements for structure, energy and fire, so it is normally checked by building control as part of the project. The approval route depends on the building and the nation, because England, Wales, Scotland and Northern Ireland have separate systems. Planning permission may also be needed for changes to appearance.
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.
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.
Should I choose a stick or unitised curtain wall?
A stick system is assembled on site and generally suits low-rise buildings, entrances and smaller screens, with simpler logistics. A unitised system uses factory-made panels lifted into place, which reduces site joints and work at height but needs cranage and longer planning. The building's height, access and programme usually decide which is the right fit.
