Candidate Glass Constructions for City of Westminster Projects

Option 0114mm – 18mm Multi-Ply Intumescent

EI30 Intumescent Fire-Resistant Safety Glass

Best Suited For:Classroom corridor dividing walls, library partitions, and secondary circulation routes.
Engineering Trade-Offs:Provides full 30-minute integrity and thermal insulation (surface temperature < 140°C rise) preventing clothes from igniting; dual-certified to Class 1B1 impact safety.
Option 0223mm – 28mm Multi-Ply Intumescent in Certified Steel/Hardwood Frame

EI60 Heavy-Duty Intumescent Glazed Assembly

Best Suited For:Protected primary vertical escape stairwells, school atriums, and sports hall fire separation screens.
Engineering Trade-Offs:60 minutes full fire containment; substantially heavier dead-weight (~60 kg/m²) requiring structural frame anchors and heavy-duty pivot hinges.
Option 037mm – 11mm Modified Toughened / Gel Fire Glass

E30 / EW30 High-Level Transom Glazing

Best Suited For:High-level clerestory corridor fanlights above 2200mm where thermal radiation does not endanger escaping pupils.

Architectural Design & Safety Checklist

Verify adherence to Building Bulletin 100 (BB100: Design for fire safety in schools) and Approved Document B.
Mandate dual certification: All glass below 1500mm in school doors and below 800mm in corridor screens MUST achieve both fire rating (EI) and BS EN 12600 Class 1B1 impact safety.
Verify permanent indelible fire safety kitemarks are visible after framing beads are fitted (essential for Building Control / Fire Authority sign-off).
Specify edge tape protection: Intumescent fire interlayers are sensitive to moisture and UV degradation; verify sealed perimeter tapes are intact prior to glazing.
Ensure door vision panels comply with Approved Document M: minimum glazed zone between 500mm and 1500mm from floor level to ensure small children and wheelchair users are visible.
