Middlebury Replaces Unsafe Wired Glass

After learning about the hazards of traditional wired glass and changes in the building code, MIddlebury College acted quickly to survey and catalogue every piece of traditional wired glass panel on campus. They created a spreadsheet noting the location and sizes of over 1500 pieces of traditional wired glass in doors and windows. Then, Middlebury set out to replace the wired glass with clear, safe, fire rated alternatives.
