Commercial glazed screens across Abergavenny
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.
The look of the facade depends on how the glass is held. Capped systems clamp the glass with pressure plates hidden behind a visible cover cap, while structural silicone glazing bonds the glass to carrier frames so the outside reads as a smooth, almost frameless surface.
A stick system is built on site piece by piece. Aluminium mullions and transoms are fixed to the structure first, then the glass and infill panels go in, and finally the pressure plates and caps. It suits low-rise buildings and screens but needs access to both faces.
Curtain walling needs planned upkeep. Clean frames and glass regularly, keep drainage outlets clear, and inspect gaskets, seals and fixings for shrinkage, gaps or corrosion. Failed or misted sealed units can usually be replaced individually without removing the surrounding framing.
What a typical job includes
- System selection and glass specification for the building
- Fabrication drawings and coordination with other trades
- Sealing, weathering and drainage details at all interfaces
- Survey of openings, supporting structure and access

Working in Abergavenny
- Postcodes covered
- NP7 and the surrounding area, including Brynmawr, Abertillery and Pontypool
- Coast
- Abergavenny is well inland, around 29 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Abergavenny the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 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.
- 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.

Choosing your curtain walling
Structural silicone glazing
Glass bonded to carrier frames with structural sealant, giving a flush external face with minimal visible framing.
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 Abergavenny: questions
What affects the cost of curtain walling?
The main cost drivers are facade area, system type, glass specification, infill panels, opening vents, building height and access equipment such as scaffolding, hoists or cranes. Structural silicone glazing, unitised panels, fire-resisting sections and testing requirements add cost. See the guide prices for typical ranges, and your written quote fixes the price for the specification.
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.
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.
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.
