Building Codes
Overview
  • The UBC — Uniform Building Code — has specific requirements for the use of safety glass and for egress.
  • The theory behind the use of safety glass is just that — safety.
  • It is required where someone is most likely to slip and fall against the window, ie: running towards a door or falling in a bathroom.
  • Egress is established to allow a fireman to enter a bedroom window fully loaded with gear.
  • Some local jurisdictions have developed their own codes — check for these prior to making recommendations.
  • CAUTION: It is the customer's responsibility to check that local building codes are met.
