Curtain walling in Lerwick: what to know
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.
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.
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.
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.

- Coast
- Lerwick 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 Lerwick the midwinter sun reaches about 6° above the horizon at noon, with roughly 5.5 hours of daylight, rising to about 53° and 18.5 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
- 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.

Replacement windows in Scotland can need planning permission in conservation areas, on listed buildings and on some flats. The local planning authority can confirm.
Specification choices
Opaque spandrel panels
Insulated or back-painted glass panels that hide floor slabs, ceiling voids and services while keeping the facade's appearance consistent.
Capped system
Glass clamped by pressure plates behind a visible external cap, available in different profiles and colours to emphasise the grid.
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.
Curtain Walling in Lerwick: questions
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 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.
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.
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.
