Doors & Windows with Tempered Glass | Cost & Pros & Cons

Key Takeaways

  • Tempered glass is a type of safety glass that’s stronger and safer than regular glass.
  • It’s made by heating glass to high temperatures and then rapidly cooling it.
  • Pros include increased safety, durability, and maintenance benefits.
  • Cons can include higher costs and more complex installation processes.

What is Tempered Glass?

Tempered glass is used almost everywhere (even if you don’t recognize it) – and that’s for a good reason. Tempered glass is safer compared to regular glass (we will get into that later in the article) and offers several benefits that make it a popular choice.

Also known as toughened glass, tempered glass is a type of safety glass that is produced using controlled heat or chemical processes to increase its strength, unlike regular annealed ones.

As a result of its increased tensile strength, tempered glass can withstand far greater impact, and if it eventually breaks, it shatters into small blunt pieces with no real risk of causing any serious harm to you or your loved ones.

How is Tempered Glass Made?

Remember we mentioned that tempered glass is produced through a carefully managed process? 

Well, to temper glass, the glass is heated in a furnace at over 620oC (or 1,148 Fahrenheit) and then cooled down quickly. The rapid cooling causes the outer surfaces of the glass to compress, while the inner portion remains in tension, giving it its strength.

Cost of Windows & Doors with Tempered Glass

Let’s talk numbers. Tempered glass costs more than regular glass – typically, you can expect to pay about 20-30% more for the glass pane. However, this cost can vary widely based on a few key factors:

Breakdown of Cost Factors

  • Size
  • Shape
  • Thickness
  • Customization options, such as tinting or patterns

But remember, the initial cost is only part of the story. It’s also about the value added over time.

Long-Term Cost Benefits Of Tempered Glass

The initial cost of ordering doors and windows with tempered glass might be on the higher side, but considering the long-term cost-saving benefits – it will absolutely pay for itself throughout the lifetime of the window or door.

For example, tempered glass is best for storm doors. These doors see significant foot traffic – opening, closing, and yes, even slamming – on a near-daily basis. Its durability and extended lifespan minimize the need for replacement, repairs, and maintenance costs, offering significant savings in the long run.

Pros of Doors & Windows with Tempered Glass

Doors and windows with tempered glass offer several significant benefits in terms of safety, durability, heat resistance, and versatility.

Reduced Risk of Injury

Tempered glass offers a safer option compared to regular glass. When it breaks, it shatters into small, rounded pieces instead of dangerously sharp large shards. This greatly reduces the risk of injury to you and your loved ones. It also withstands higher thermal stress and impact pressure, making it perfect for areas with widely fluctuating temperatures.

Wide Range of Applications

Tempered glass is incredibly versatile. Its durability, thermal properties, and scratch resistance make it ideal for a wide range of uses. Whether for windows or doors, tempered glass is a reliable and safety-oriented choice.

Long-term Savings 

While tempered glass may cost more upfront, its strength and durability lead to long-term savings. You’ll spend less on replacement costs, making it a smart long-term investment for your home or commercial space.

Cons of Tempered Glass

Potential Risks and Limitations

Despite its strength, tempered glass is not indestructible. A well-placed impact at the right angle can still cause it to break. And when it breaks, it’s done; you’ll need a full replacement, which can be more costly than simply replacing a cracked pane of regular glass.

When To Use Doors & Windows with Tempered Glass

So when should you opt for tempered glass? It’s not just a matter of personal preference; more often than not, building codes require that tempered glass be used for the safety of patrons.

Specific Applications and Settings

Here are a few places where tempered glass shines:

  • Patio or balcony doors
  • Any home or commercial space located in an area prone to high winds
  • Near doorways and stair landings
  • Bathroom windows

And let’s not forget about building codes. Many local regulations require tempered glass in certain areas of the home for safety reasons. Always check your local codes to see where you might need to use tempered glass to stay compliant.

Regulatory Guidelines and Recommendations

Most importantly, safety is a top priority. That’s why building codes often specify areas in a home where tempered glass is a must. 

These guidelines are in place to protect you and your family, especially in high-risk areas like bathrooms, near doors, and around staircases. Because of its break-safe characteristics, tempered glass is often required in these potentially hazardous situations.
