Glass strength planning brief
Build a clear project brief for a qualified specialist. This workflow records assumptions and unknowns; it does not approve thickness, capacity or safety.
Opening, supports and use
PlanningStarts from your shared draft size if known; confirm the clear opening separately or leave blank as unknown.
Clear spans differ from overall glass dimensions. Blank remains unknown in the brief.
Record continuous bearing, fixing locations and support stiffness, or leave unknown.
Leave blank if unknown. Specialist determines the project design load and combinations.
Foot traffic, trolleys, loads and contact patch; units and source required.
Complete if people may walk on the glass.
Specialist assesses retained load capacity and consequences of failure; laminate chemistry alone does not prove it.
For example window, balustrade or floor; structural applications need specialist review.
Ordered layers start at the outside or stated reference face.

Specialist brief
Every blank field stays unknown. A stock thickness or example laminate is not selected as a safe construction.
SPECIALIST PLANNING BRIEF — GL01; no structural or thickness approval Use: Vertical infill; project-specific structural assessment required Clear opening: 1200 × 800 mm (distinct from overall panel size; supplied dimensions require confirmation) Proposed overall panel: 1200 × 800 mm; rectangle; specialist to confirm bearing allowance and final dimensions Proposed assembly only: 6mm clear toughened (6 mm nominal); not an approved construction Location / orientation: Not supplied / Vertical support: Unknown — specialist to confirm loadCategory: Unknown — specialist to determine distributedLoad: Unknown — specialist to determine concentratedLoad: Unknown — specialist to determine contactArea: Unknown — specialist to determine windLoad: Unknown — specialist to determine duration: Unknown — specialist to determine environment: Unknown — specialist to determine slipTreatment: Unknown — specialist to determine postBreakage: Unknown — specialist to determine bearing: Unknown — specialist to determine deflection: Unknown — specialist to determine fireDirection: Unknown — specialist to determine Outstanding information: support, loadCategory, distributedLoad, concentratedLoad, contactArea, windLoad, duration, environment, slipTreatment, postBreakage, bearing, deflection, fireDirection EN16612 concerns linearly supported infill lateral resistance. EN16613 supplies interlayer-property testing; neither is a blanket approval for floors, barriers or point fixings. Specialist to determine loads, applicable design basis, supporting structure, serviceability, breakage consequences, redundancy, fixing and installation requirements. Maintenance-only rooflights are not automatically suitable for regular walking. Wet walkways need project-specific slip assessment.
