Curtain walling for homes and businesses in Port Glasgow
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.
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.
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.
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.
Included as standard
- Sealing, weathering and drainage details at all interfaces

- Coast
- Port Glasgow 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 Port Glasgow the midwinter sun reaches about 11° above the horizon at noon, with roughly 6.7 hours of daylight, rising to about 58° and 17.3 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 Scotland
- Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.

Curtain Walling in Port Glasgow: questions
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.
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.
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.
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.
