Curtain walling for homes and businesses in Harlow
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.
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.
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.

- Coast
- Harlow is well inland, around 38 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Harlow 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
- City-centre facades often need crane or hoist bookings, pavement or road licences, out-of-hours deliveries and close coordination with other trades. Tight sites need careful sequencing, and unitised panels can reduce the amount of work at height.
- 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.

If the glass sits in a fire-resisting door or screen, such as a flat entrance door or a commercial corridor screen, it must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.
Choosing your curtain walling
Integrated opening vents
Top-hung or parallel-opening vents built into the curtain wall grid to provide natural ventilation without breaking the facade line.
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.
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 Harlow: questions
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.
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.
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 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.
