Most homeowners only consider tempered glass after someone tells them they need it.
In many cases, it is not optional. Building codes require tempered glass windows in specific locations to reduce the risk of injury.
This guide explains when to use tempered windows, where building codes require them, and why they matter for safety and compliance.
We're ready and able to assist with any questions or concerns.
When Should Homeowners Use Tempered Glass Windows? (Quick Answer)
Windows need to be tempered when they are installed in areas where human impact is likely.
This includes:
Near doors
In bathrooms and showers
Close to the floor
Along stairways and landings
Building codes require tempered glass in these areas because it breaks into small, less dangerous pieces. This helps reduce the risk of serious injury.
Longhorn Windows carries a variety of tempered glass options.
What Is Tempered Glass (and Why Is It Safer)?
Tempered glass is a type of safety glass that undergoes a heat-treatment process to increase its strength.
Compared to standard glass, this type of glass is:
Stronger under impact
More durable under temperature changes
Safer when broken
Instead of breaking into sharp shards, tempered glass shatters into small, rounded pieces.
Building codes require tempered glass windows in areas where people are more likely to fall or make contact with glass.
Tempered Glass Window Code Requirements
Building codes outline specific situations where tempered glass is required. While exact measurements may vary slightly by location, the general rules remain consistent.
Common Situations Where Tempered Glass Is Required:
Near doors: Windows located within a certain distance of a door
Near the floor: Windows installed low to the ground
Bathrooms and wet areas: Areas with higher slip risk
Stairways and landings: Fall-prone locations
These tempered window requirements exist to reduce injury risk in high-impact zones.
Always confirm local requirements, as exact distances and rules can vary by city.

Do Bathroom Windows Require Tempered Glass?
In most cases, building codes require safety glass.
Building codes usually require tempered glass for bathroom windows near bathtubs, shower doors, or other wet areas.
Water increases the risk of slipping, which makes impact more likely.
What About Shower Windows?
Building codes almost always require tempered glass for shower windows.
These areas are considered high-risk because:
Surfaces are slippery
Movement is limited
Falls are more likely
Local codes may vary slightly, but most require tempered glass in these situations.

Windows Near Doors: Do They Need Tempered Glass?

Tempered Glass for Windows Near Floors & Stairs
Windows installed close to the floor must often meet tempered window code requirements.
Why this matters:
People can fall into low windows
Larger glass panels increase impact risk
Stairways and landings also require tempered glass because of the increased fall risk.
Most building codes classify these areas as hazardous locations.
