Whether tempered glass windows are worth it comes down to where the glass goes. The building code requires it in several spots, and in a few others, the added protection is well worth the cost. Here is how to tell the two apart.
Where Tempered Glass Windows are Required by Code
Building codes require tempered glass in a few specific locations. These are the spots where a window is most likely to be accidentally struck.
The Three Places Code Requires It
Tempered glass is mandatory in these situations:
- Near tubs and showers. Any window around a bathtub or shower must be tempered.
- Close to a door swing. Windows within a set distance of a swinging door must be tempered.
- Low to the floor. Glass less than 18 inches above the finished floor must be tempered.
Why We Use It as a Standard
We treat tempered glass as a baseline rather than an afterthought, and we use it wherever the code calls for it. Meeting these requirements protects your family and keeps your project inspection-ready from the start.
Key Takeaway: These code rules are not arbitrary. Each one covers a location where broken glass could seriously hurt someone.
When Tempered Glass is Worth Choosing Beyond Code
Sometimes tempered glass makes sense even where the code does not demand it. The deciding factor is usually the risk of impact. Outside those code-required spots, the call is yours to make.
Homes Exposed to Impact
A good example is an atrium ranch that backs onto a golf course. Stray golf balls can strike that back wall, so tempered windows there add a real layer of protection. In a setting like that, the upgrade is easy to justify.
How Tempered Glass Breaks
Tempered glass behaves much like the windshield on your car. It cracks and holds together instead of shattering into sharp pieces. That single difference is what makes it safer:
- It resists breaking apart on impact.
- It cracks like a windshield rather than scattering shards.
- It offers more protection where flying objects are a concern.
Pro Tip: If your home backs onto a golf course or faces another impact risk, ask about tempered glass for those exposed walls even where code does not require it.

Is the Added Cost Worth It?
The only real downside to tempered glass is that it costs a little more than standard glass. For most of your home, the code settles it for you.
What Tempered Glass Windows Cost
Tempered glass adds a modest amount to the price of a window. Where the code requires it, the cost is simply part of doing the job correctly. Where it is optional, the extra protection is what you are paying for. Either way, you will know the exact price before any work begins.
Quoting Both Options
When tempered glass is a choice rather than a requirement, we can quote your project both ways. You get to compare the standard option against the tempered option and decide what fits your home and budget.
Key Takeaway: You never pay for tempered glass you do not need. The cost only applies where code calls for it, or the extra protection is genuinely worth it.
The Bottom Line On Tempered Glass
So, are they worth it? In the spots the code covers, the choice is already made, and the safety is real, not an upsell. Where your home faces a true impact risk, a small extra cost buys protection that is easy to justify.
