Curtain wall glass replacement for homes and businesses in Hertford
A stick system is built on site piece by piece. Aluminium mullions and transoms are fixed to the structure first, then the glass and infill panels go in, and finally the pressure plates and caps. It suits low-rise buildings and screens but needs access to both faces.
The price depends on the facade area, the system type, glass specification such as solar control or triple glazing, infill panels, opening vents, building height and access equipment, and design and testing requirements. Replacement units also depend on how the glass is retained. See the guide prices for typical ranges.
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.
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.

About Hertford for this job
- Postcodes covered
- SG13, SG14 and the surrounding area, including Hoddesdon, Welwyn Garden City and Hatfield
- Coast
- Hertford is well inland, around 49 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Hertford 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.

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
Integrated opening vents
Top-hung or parallel-opening vents built into the curtain wall grid to provide natural ventilation without breaking the facade line.
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.
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.
Curtain Walling in Hertford: 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.
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.
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.
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.
