Wind-Borne Debris Zone Expansion Mandates Impact Glazing Broadly
Wind-borne debris zone building codes across Florida, Texas, and Gulf Coast jurisdictions have expanded rapidly since 2023, mandating impact-rated glazing in newly designated coastal zones that previously allowed standard glass without restriction. More than fifteen additional counties adopted expanded wind-borne debris zone codes since 2023, each requiring documented large and small missile impact certification before developers can obtain building permits for new construction. Fabricators offering pre-certified, large-format impact glazing systems are capturing specification share fastest, while fabricators without documented impact testing face growing exclusion from coastal zone construction projects entirely across the affected jurisdictions.
Market Impact: Adds 16 percent certified volume growth
