About curtain walling in Gravesend
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.
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 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.
What a typical job includes
- Survey of openings, supporting structure and access
- System selection and glass specification for the building
- Sealing, weathering and drainage details at all interfaces
- Final inspection, clean and maintenance guidance
Working in Gravesend

- DA11, DA12 and the surrounding area, including Grays, Strood and South Ockendon
- Coast
- Gravesend is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Facades near the sea face salt-laden wind and driving rain, which attack frame finishes and stress seals. Suitable coating specifications, regular washing, gasket checks and higher design wind loads for exposed sites all matter for curtain walling there.
- Daylight and sun
- In Gravesend 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.

Approved Document L sets the minimum energy performance for replacement windows and doors in existing homes in England: a U-value of 1.4 W/m²K, or Window Energy Rating band B for windows; doors can instead meet a Door Set Energy Rating (band B, or band C for doors more than 60% glazed); rooflights need 2.2 W/m²K.
Specification choices
Capped system
Glass clamped by pressure plates behind a visible external cap, available in different profiles and colours to emphasise the grid.
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 Gravesend: 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.
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.
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.
