Thetford: glazed facade systems
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.
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.
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.
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.

Local details for Thetford
- Postcodes covered
- IP24 and the surrounding area, including Mildenhall, Bury St Edmunds and Diss
- Coast
- Thetford is well inland, around 50 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Thetford the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 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.

Specification choices
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.
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 Thetford: questions
Do glazed screens in offices and entrances need markings?
Large areas of clear glass that people could walk into need to be made visible. In England, the guidance for buildings other than dwellings puts manifestation at 850–1000mm and 1400–1600mm above the floor, and workplace rules across Great Britain require glass to be marked where needed for safety. Frosted bands or logos can meet this.
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.
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 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.
