Curtain wall glass replacement for homes and businesses in Cirencester
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.
A unitised system arrives as storey-height panels assembled and glazed in a factory, which are lifted into place and interlocked. Fewer joints are made on site, which can reduce the risk of air and water leaks from site workmanship, but cranage and lead times need careful planning.
The Centre for Window and Cladding Technology publishes the Standard for systemised building envelopes, the recognised UK industry standard for specifying, testing and assessing curtain walling. It draws in BS EN 13830 and the relevant building regulations, and is often referenced in commercial specifications.
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.
Included as standard
- Fabrication drawings and coordination with other trades

Local details for Cirencester
- Postcodes covered
- GL7 and the surrounding area, including Stroud, Cheltenham and Swindon
- Coast
- Cirencester is well inland, around 30 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Cirencester 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 England
- 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.

Choosing your curtain walling
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.
Solar control glass
Coated glass that limits solar heat gain on sunny elevations while keeping good daylight, reducing overheating and glare inside.
Curtain Walling in Cirencester: 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.
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.
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 long does a curtain walling project take?
Timescales depend on size and complexity. Design, approvals and fabrication of framing and glass usually take several weeks to a few months before installation starts. Installation then depends on the facade area, access and sequencing with other trades. Replacing individual units is much quicker once the glass is made.
