Commercial glazed screens across Blackburn
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.
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.
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.
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.

About Blackburn for this job
- Postcodes covered
- BB2, BB1, BB3 and the surrounding area, including Darwen, Accrington and Chorley
- Coast
- Blackburn is well inland, around 29 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Blackburn the midwinter sun reaches about 13° above the horizon at noon, with roughly 7.2 hours of daylight, rising to about 60° and 16.8 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.

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.
Choosing your curtain walling
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.
Integrated opening vents
Top-hung or parallel-opening vents built into the curtain wall grid to provide natural ventilation without breaking the facade line.
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 Blackburn: 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.
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.
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.
How does curtain walling keep water out?
Curtain walling uses outer gaskets and seals to shed most rain, with drainage routes inside the framing that collect any water getting past them and lead it back outside. Inner seals then provide the air seal. Keeping drainage outlets clear and gaskets in good condition is essential, because blocked drains or shrunk seals can let water into the building.
