Curtain wall glass replacement in Didcot
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.
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.
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.

About Didcot for this job
- Postcodes covered
- OX11 and the surrounding area, including Abingdon, Wantage and Oxford
- Coast
- Didcot is well inland, around 80 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Didcot 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.

Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.
Options to choose between
Opaque spandrel panels
Insulated or back-painted glass panels that hide floor slabs, ceiling voids and services while keeping the facade's appearance consistent.
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.
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 Didcot: questions
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.
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 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 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. Your written quote sets out the expected programme.
