Technical Evaluation

Candidate Glass Constructions for Downham Market Projects

Option 0128mm – 44mm Double or Triple IGUs

Thermally Broken Stick Curtain Walling (Pressure Plate / Capped)

Best Suited For:Low-to-medium rise commercial office buildings (1 to 5 storeys) and school atriums.
Engineering Trade-Offs:Highly adaptable on site; lower upfront tooling cost; requires on-site scaffolding and weather-dependent external glazing installation.
Option 0232mm – 48mm High-Performance Triple IGUs

Unitised Curtain Walling (Factory-Assembled Cassettes)

Best Suited For:High-rise urban office towers and fast-track city centre developments.
Engineering Trade-Offs:Factory-controlled quality and rapid crane-assisted installation without scaffolding; requires substantial upfront design lead time and higher transport costs.
Option 0332mm – 40mm Stepped Double IGUs with UV-Resistant Silicone Secondary Seal

Structural Silicone Glazing (SSG / Frameless Exterior)

Best Suited For:Monolithic flush-glass architectural facades with concealed mullions.
Engineering Trade-Offs:Stunning seamless glass aesthetic; requires certified two-part structural silicone (ETAG 002 compliant) and strict quality-control adhesion testing.

Architectural Design & Safety Checklist

Calculate site-specific wind pressure to BS EN 1991-1-4 (Eurocode 1) factoring in building height, terrain category, and corner vortex amplification (cpe,10 / cpe,1).
Determine solar factor (g-value) per elevation: South and West elevations typically require g <= 0.30; North elevations benefit from higher daylight transmittance.
Detail horizontal and vertical fire stopping at each floor slab edge compliant with CWCT standard and Approved Document B (combustible cladding limits under Regulation 7(2)).
Incorporate drainage weep holes and pressure equalisation chambers to satisfy CWCT water penetration test at 600 Pa test pressure (Class R7).
Verify framing deflection limits: CWCT mullion deflection must not exceed L/200 or 15mm max under serviceability wind load (2400 Pa).
Ensure setting blocks are positioned at quarter points per BS 6262-6 with 80–90 Shore A hardness to distribute dead load directly into transom anchors.

Governing British & European Standards

CWCT Standard for Systemised Building Envelopes
Mandatory test sequence: 600 Pa air permeability (Class A4), 600 Pa water tightness (Class R7), 2400 Pa wind serviceability, and 3600 Pa wind safety.
Building Safety Act 2022 & Approved Document B
Stringent non-combustibility rules (Class A1 / A2-s1, d0) for external wall assemblies on buildings over 18m (or 11m in Scotland).
BS EN 1279 Parts 2 & 3
Hermetic seal integrity and argon gas retention (<1% annual loss) verification for commercial envelope units.
BS EN 14179-1 (HST)
Mandatory heat soak testing on all exterior toughened panes to eliminate spontaneous NiS fracture risk at height.

Downham Market Site Logistics & Crane Handling

Lifting Equipment:Oversized panels require spider crane or vacuum lifter offloading.
Structural Substrate:Dead-load and wind-load brackets must be anchored to structural concrete slabs using cast-in channels or engineered chemical anchors with verified pull-out values.
Site Tolerances:Concrete slab edge tolerances (±25mm) must be absorbed within adjustable facade bracket 3-axis slot design.
