We then provide a detailed, fixed-price quotation with no hidden costs.

Curtain Walling in Belfast: Local Considerations
Shankill, Falls Road, and the wider residential areas of the city have neighbourhood high streets that we serve regularly, fitting robust roller shutters and security doors alongside standard shopfront replacement for independent retailers and convenience businesses, and we extend our coverage out to Holywood and the wider Belfast commuter belt.
The Cathedral Quarter has become Belfast's most distinctive independent retail and hospitality district, built around a concentration of Victorian warehouse and merchant buildings converted into bars, restaurants, and creative-industry premises. A number of these buildings sit within conservation area designation, and Belfast City Council pays close attention to how new shopfronts respect the exposed brick and cast-iron detailing typical of the quarter's warehouse architecture. We design heritage-sensitive aluminium shopfronts for these conversions, balancing the practical need for security and thermal performance with the character the council expects to see retained.
Why Choose Our Curtain Walling in Belfast
Belfast businesses choose us for our combination of competitive pricing, professional installation, and responsive ongoing support for all curtain walling systems.
Full-Height Glazed Facades
Curtain walling spans between floor slabs, creating continuous glazed elevations that maximise natural light, provide uninterrupted views, and give the building a contemporary commercial aesthetic that traditional punched-window construction cannot achieve.
Engineered Wind Load Resistance
Unlike shopfront systems designed for single-storey use, curtain wall mullions are structurally calculated to resist the full design wind load for the building height and exposure. This provides documented structural performance that satisfies Building Regulations and building control requirements.
Thermal and Acoustic Performance
Thermally broken mullions and transoms, combined with high-performance glazing and insulated spandrel panels, achieve the facade U-values and acoustic ratings required for modern commercial buildings, including BREEAM-rated and Part L compliant developments.
Design Flexibility
Curtain wall grids can be configured in any module width and height, with a mix of fixed glazing, opening vents, spandrel panels, and louvre sections. This flexibility allows the facade design to respond to internal layouts, ventilation strategy, and the architect's aesthetic intent.

How It Works
From initial enquiry to completed installation in Belfast — here is what to expect when you choose Grewal Shopfront & Shutters for your curtain walling project.
Design Brief
We discuss the facade area, building height, structural frame type, and performance requirements — thermal, acoustic, solar, and fire — to establish the appropriate curtain wall system.
Site Survey & Structural Review
Our surveyor measures the facade, records the structural fixing points, and coordinates with the project structural engineer to confirm bracket positions and load capacities.
Detailed Design & Calculations
We prepare structural calculations for mullion sizing, thermal calculations for Part L compliance, and detailed fabrication drawings showing every mullion, transom, and infill panel.
Fabrication & Installation
Aluminium sections are fabricated, powder-coated, and delivered to site. Our installation team erects the framework, glazes the infills, installs fire stopping, and commissions any opening vents.
Testing & Handover
On completion, we carry out a hose test to verify watertightness and provide all documentation including structural calculations, fire-stopping certificates, and maintenance guidance.
What Does Curtain Walling Cost?
Curtain wall pricing is typically quoted per square metre of facade area and depends on the system type, glazing specification, opening vent requirements, and complexity of the facade geometry.
All prices exclude VAT. Final cost confirmed after site survey and structural design.
Curtain Walling in Belfast — Frequently Asked Questions
A shopfront is a ground-floor glazed facade installed within a single structural opening, typically up to one storey in height. Curtain walling is a multi-storey facade system that spans between floor slabs and is designed to resist the wind loads, thermal movements, and weather conditions associated with taller buildings. For ground-floor commercial frontages, a shopfront system is usually more cost-effective; for multi-storey facades or large glazed areas spanning above ground floor, curtain walling is the appropriate specification.
Installation timescales depend on the system type and facade area. A typical two-storey stick-built curtain wall of 50 to 100 m² can be erected and glazed within two to three weeks. Larger unitised installations proceed at a faster rate per square metre once the initial set-out is complete, but require more upfront design and manufacturing time.
Yes. Curtain walling installations require Building Regulations approval for structural performance, thermal performance (Part L), fire stopping at compartment boundaries, and safety glazing compliance. We manage the Building Regulations application and provide all structural calculations, thermal calculations, and fire-stopping details as part of our project service.
Yes. Opening vents — typically top-hung or parallel-opening — can be integrated within the curtain wall grid to provide natural ventilation. These openings are fitted with the same weather sealing and locking hardware as standalone commercial windows, and are positioned within the grid layout to suit the building's ventilation strategy.
