Commercial glazed screens across Carlisle
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.
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.
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.
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.
Included as standard
- Survey of openings, supporting structure and access

About Carlisle for this job
- Postcodes covered
- CA1, CA2, CA3 and the surrounding area, including Annan, Penrith and Lockerbie
- Coast
- Carlisle sits roughly 11 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. 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 Carlisle the midwinter sun reaches about 12° above the horizon at noon, with roughly 6.9 hours of daylight, rising to about 58° and 17.1 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.
What you can choose
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.
Integrated opening vents
Top-hung or parallel-opening vents built into the curtain wall grid to provide natural ventilation without breaking the facade line.
Curtain Walling in Carlisle: questions
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.
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.
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.
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.
