Texas Hailstorms & Severe Weather: Protecting Your Dallas & Houston Home Windows

Key Takeaways for Homeowners

  • Spring severe thunderstorms in Texas frequently generate golf-ball to baseball-sized hail traveling at 70+ mph.
  • Tempered outer glazing is four times stronger than standard annealed glass, resisting hail impact fractures.
  • TDI (Texas Department of Insurance) coastal windstorm certification is required for Gulf Coast counties.
  • Heavy-duty sash hardware prevents sashes from being forced open by extreme positive and negative wind pressures.
## Severe Weather Fenestration in the Lone Star State Texas experiences some of the most dynamic weather in North America—from 2-inch hail and tornado squall lines across Dallas-Fort Worth to tropical storms hitting Houston, Galveston, and Corpus Christi. Standard residential glass is highly vulnerable to catastrophic shatter during these weather events. ### Tempered vs. Laminated Glass for Hail Defense 1. **Tempered Glass (Heat-Treated):** Offers 4x mechanical strength against direct hail strikes. If broken, it crumbles into small, dull granules rather than dangerous shards. 2. **Laminated Safety Glass:** Adds a tough interlayer that keeps the window opening sealed even if the outer pane is compromised by flying debris.
