Aluminium curtain wall in Aberdare
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.
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.
Wind load on a facade rises with height, exposure and building shape, and it decides the mullion size, bracket design and glass thickness. Calculations for the specific site are part of the design, so a system suited to a sheltered ground-floor screen may not suit an exposed upper storey.
Included as standard
- Final inspection, clean and maintenance guidance

- Supply and installation of framing, glass and panels
- Survey of openings, supporting structure and access

About Aberdare for this job
- Postcodes covered
- CF44 and the surrounding area, including Mountain Ash, Rhondda and Merthyr Tydfil
- Coast
- Aberdare is well inland, around 29 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Aberdare 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. 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.

Glass in a fire-resisting door or screen must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.
Options to choose between
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.
Structural silicone glazing
Glass bonded to carrier frames with structural sealant, giving a flush external face with minimal visible framing.
Capped system
Glass clamped by pressure plates behind a visible external cap, available in different profiles and colours to emphasise the grid.
Curtain Walling in Aberdare: questions
What glass is used in curtain walling?
Curtain walling normally uses sealed double or triple glazed units, with toughened or laminated panes chosen for safety, security and wind load. Coatings control heat loss and solar gain, and heat-soaked toughened glass is often specified for upper levels. Where fire resistance is needed, a tested fire-resistant glazing system is used instead of standard glass.
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.
How should curtain walling be maintained?
Curtain walling should be cleaned regularly and inspected at planned intervals. Check that drainage outlets are clear, gaskets have not shrunk or slipped, sealant joints are intact and fixings show no corrosion. Address misted or cracked units early. A simple maintenance schedule kept with the building records helps facilities teams spot problems before they become leaks.
