Commercial glazed screens for homes and businesses in Bishops Stortford
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.
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.
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.
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
- System selection and glass specification for the building
- Survey of openings, supporting structure and access
- Sealing, weathering and drainage details at all interfaces
- Final inspection, clean and maintenance guidance

- Coast
- Bishops Stortford is well inland, around 41 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Bishops Stortford 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 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.

What you can choose
Solar control glass
Coated glass that limits solar heat gain on sunny elevations while keeping good daylight, reducing overheating and glare inside.
Structural silicone glazing
Glass bonded to carrier frames with structural sealant, giving a flush external face with minimal visible framing.
Opaque spandrel panels
Insulated or back-painted glass panels that hide floor slabs, ceiling voids and services while keeping the facade's appearance consistent.
Curtain Walling in Bishops Stortford: 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.
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.
Does new curtain walling need building regulations approval?
New curtain walling is building work that has to meet requirements for structure, energy and fire, so it is normally checked by building control as part of the project. The approval route depends on the building and the nation, because England, Wales, Scotland and Northern Ireland have separate systems. Planning permission may also be needed for changes to appearance.
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.
