Wind rating & compliance

Wind rating and glazing compliance checks on every window and door

Give a job its wind rating and Alumetric checks each window and door when you generate it: the unit size against the supplier's limits for that wind, the mullions, transoms and interlocks against their loading tables, the glass for its size, and safety glass where people could walk into it. Each problem is explained, often with a fix you apply in one click. The checks are an aid to your judgement, not certification.

Wind rating and glazing compliance

Every window and door checked against the job's wind rating, the supplier's limits and the safety-glass rules, with one-click fixes.

The job's wind rating

  • Rate each job from the builder's or engineer's plans: an AS 4055 class such as N3 or C2, or the engineer's design pressures
  • One default window sill height per job covers the safety-glass rules for every window; doors stand on the floor and need none
  • Corner windows and exposed sites are taken into account where the rating system has figures for them

What is checked

  • Frame and sash sizes against the supplier's size limits for the wind class
  • Mullions, transoms and sliding interlocks against the supplier's loading tables
  • The glass in every pane for its size, from the glass supplier's chart or a calculated estimate marked as indicative
  • Safety glass for doors and the panes beside them, low glass and wet areas such as bathrooms and showers
  • Water resistance, where the supplier gives water figures

Results and fixes

  • A plain verdict on every item: Compliant, Review, Needs input, Not rated or Not compliant
  • One-click fixes such as a stronger glass for every pane or an extra mullion or transom, and the check runs again
  • A part with no supplier data is counted as unchecked beside the verdict, never as a fail
  • Change the job's wind rating and every saved item is checked again
  • Nothing is ever blocked: you can save, quote and print whatever the result

Setting it up

  • Switched on once in Settings; while it is off, nothing changes
  • Your supplier's size limits and loading tables are entered once per system from their technical manual, and we can help you set them up
  • The wind rating prints on the quotation, the window labels and the glazing certificate
