Glazed aluminium shopfront and curtain walling on a commercial building

SIVAL Technical Team2 min read

Curtain walling is not just for towers. The same stick-built aluminium technology that wraps office blocks also builds café frontages, showrooms, gyms, surgeries and school entrances — anywhere a wall wants to be mostly glass. Our SV-5200 Facade covers exactly this ground: a 52mm grid of mullions and transoms, glazed on site, tested to the curtain-walling standard EN 13830.

Shopfront or curtain wall?

The trade distinction is roughly this: a shopfront is a ground-floor glazed frontage set within the structure, usually incorporating the entrance; curtain walling hangs in front of or between floor slabs and can run continuously across storeys. Smaller commercial jobs often blur the two — a double-height glazed entrance is technically curtain walling even on a modest building. The system logic is the same either way.

What the system provides

  • Structure: aluminium mullions and transoms sized to spans and wind loads, with steel reinforcement where spans demand it.
  • Glazing freedom: vision glass, insulated spandrel panels, openable inserts and doors all sit in the same grid.
  • Weather performance: pressure-equalised drainage and EN 13830 type testing for air, water and wind.
  • Appearance: standard pressure-plate caps, slimmer feature caps, or a structurally glazed look via our SV-5200 Facade structural-glazing version where the grid disappears behind flush glass.

Doors, security and extras

Commercial entrances take punishment, so doors within the grid are specified accordingly — from standard aluminium shopfront doors for everyday retail duty to heavier options for schools and late-opening premises. Overnight security can add tested roller shutters, and solar control glass or external brise soleil keeps south-facing frontages workable in summer.

How a project runs

Smaller commercial glazing follows a predictable path: enquiry with drawings or photographs, quotation, technical survey, fabrication drawings for sign-off, then manufacture and installation by approved partners — with structural calculations and U-value reports supplied for building control. Planning consent is usually the client's early job; material change to a shopfront in a conservation area generally needs it, so start that conversation with your local authority in parallel.

Getting a price

Send elevations, rough dimensions and intended use through the quote form — commercial enquiries are welcome from single shopfronts upwards, and quotations come back itemised so main contractors can compare packages properly. The full architectural range, including cladding and glass roofs, is here.

This article is general guidance, not a project specification. Performance figures such as U-values depend on configuration and glazing, and your quotation states the tested values for your exact specification.

Questions Answered

What is EN 13830?

EN 13830 is the European product standard for curtain walling. It defines type testing for air permeability, watertightness, wind resistance and impact safety, so a tested system arrives with proven weather performance rather than promises. SIVAL facade systems are tested to this standard.

Can curtain walling include opening windows and doors?

Yes. Openable vents, concealed-vent windows and full entrance doors all install within the mullion-and-transom grid, sharing its sightlines. This is normal practice — a frontage can combine fixed vision glass, opening vents for ventilation and a heavy-duty entrance door in one framed composition.

Do I need planning permission for a new shopfront?

Often, yes — replacing or materially altering a shopfront usually needs planning consent, and conservation areas add stricter tests on materials and proportions. Listed buildings need listed building consent too. Check with your local planning authority before ordering; fabrication drawings can support the application.
