Candidate Glass Constructions for Tref-y-Clawdd Projects

Option 0133mm – 40mm (e.g. 10T + 1.52 Ionoplast + 10T + 1.52 Ionoplast + 10T)

Triple-Ply Structural Walk-on Panel with Sacrificial Top Ply

Best Suited For:Commercial atrium bridges, restaurant wine-cellar display floors, and public museum viewing platforms.
Engineering Trade-Offs:Designed with triple-layer redundancy: If the top sacrificial pane is scratched or broken, the bottom two plies safely support the full design pedestrian live load.
Option 0250mm – 65mm Walk-on IGU (33mm Laminated Top + 16mm Cavity + 10mm Toughened Bottom)

Double Glazed Structural Walk-on Rooflight Assembly

Best Suited For:External rooftop terraces and lightwells positioned directly above occupied heated commercial office or residential space.
Engineering Trade-Offs:Combines structural walk-on capability with Approved Document L thermal insulation (Ug <= 1.1 W/m²K) and condensation prevention.
Option 0333mm – 38mm Structural Laminate with Acid-Etched or Frit Dot Matrix

High-Traction Anti-Slip Textured Glass Panel

Best Suited For:External wet-weather footbridges, shopping center pedestrian stairs, and outdoor rooftop walkways.
Engineering Trade-Offs:Acid-etched or ceramic frit texture guarantees wet slip resistance (PTV >= 36); slightly diffuses direct downward visibility.

Architectural Design & Safety Checklist

Verify design imposed floor load to BS EN 1991-1-1 (Eurocode 1: Category C/D): Typically 5.0 kN/m² uniformly distributed load (UDL) plus 3.6 kN to 7.5 kN concentrated point load (Qk).
Mandate slip resistance testing to BS EN 16165:2021 Annex C and BS 7976-2: Pendulum Test Value (PTV) must be >= 36 under wet conditions using Slider 96 (shod foot) and Slider 55 (barefoot) to achieve HSE Low Slip Potential.
Detail full structural redundancy: Calculations must demonstrate that if the top sacrificial ply fractures, the remaining intact plies safely support total design load with deflection < L/500.
Specify continuous 50–60 durometer EPDM perimeter setting blocks (minimum 20mm rebate bearing width) to eliminate metal-on-glass point loading.
Ensure setting blocks comply with BS 6262-6 rules and provide continuous vapor-sealed drainage pathways beneath the lower glass rebate.

Governing British & European Standards

BS EN 1991-1-1 (Eurocode 1: Imposed Floor Loads)
Mandatory structural verification under uniformly distributed (5.0 kN/m²) and concentrated point loads (Qk 3.6–7.5 kN).
BS EN 16165:2021 Annex C & BS 7976-2
Pendulum Test Value (PTV) >= 36 required for wet slip compliance under UK Health and Safety Executive (HSE) rules.
Approved Document K & L
Pedestrian impact containment and thermal performance (Ug <= 1.1 W/m²K) for rooflights over habitable heated spaces.
BS EN 16613
Interlayer effective thickness calculation evaluating shear modulus G under long-term dead and short-term imposed live loads.

Tref-y-Clawdd Site Logistics & Crane Handling

Lifting Equipment:Oversized panels require spider crane or vacuum lifter offloading.
Structural Substrate:Perimeter steel or concrete supporting rebate must be engineered with maximum deflection < L/500 under total design load.
Site Tolerances:Rebate must be fabricated 100% planar and square; any twisting of the steel framework will induce fatal torsion fracture in thick multi-ply glass.

Procurement Advice for Tref-y-Clawdd

Walk-on glass floors represent complex structural engineering assemblies. A chartered structural engineer (MIStructE) must calculate and sign off the exact glass thickness, interlayer selection, and support frame bearing details.
