Window Replacement: Tempered vs. Regular Glass

When it comes to upgrading your home windows in Bensalem, PA, owners often find themselves choosing between tempered glass and regular glass. This decision can impact not only the aesthetics of your home but also its safety, energy efficiency, and overall value. Let’s break down the differences between tempered glass and regular glass to help you make an informed choice for your next window replacement.

What is Tempered Glass?

Tempered glass, also known as toughened glass, is a type of safety glass that undergoes a special heat treatment process. This process involves heating the glass to a high temperature and then rapidly cooling it. This makes the glass much stronger than regular glass and less likely to shatter into sharp, dangerous pieces.

Key Benefits of Tempered Glass

  • Safety: One of the primary reasons homeowners opt for tempered glass is its safety features. When broken, tempered glass shatters into small, blunt pieces, reducing the risk of injury.
  • Strength: Tempered glass is four to five times stronger than regular glass. This makes it more resistant to impact and thermal stress, which is particularly beneficial in areas with extreme weather conditions.
  • Heat Resistance: Tempered glass can withstand higher temperatures without breaking, making it ideal for windows exposed to direct sunlight.
  • Enhanced Security: The added strength of tempered glass provides an extra layer of security, making it more difficult for intruders to break through your windows.

What is Regular Glass?

Regular glass, also known as annealed glass, is the most common type of glass used in new windows. It is made by slowly cooling molten glass to room temperature. While it is less expensive than tempered glass, it lacks the enhanced safety and strength features.

Key Benefits of Regular Glass

  • Cost-Effective: Regular glass is generally more affordable than tempered glass, making it a popular choice for budget-conscious homeowners.
  • Versatility: Regular glass can be easily cut into various shapes and sizes, offering greater flexibility in design options.
  • Clarity: Regular glass provides excellent clarity and is available in different thicknesses to suit various applications.

Comparing Tempered Glass and Regular Glass

When deciding between tempered glass and regular glass for home window upgrades, consider the following factors:


  • Tempered Glass: Shatters into small, blunt pieces, reducing the risk of injury.
  • Regular Glass: Breaks into large, sharp shards, posing a higher risk of cuts and injuries.


  • Tempered Glass: Four to five times stronger than regular glass, offering better resistance to impact and thermal stress.
  • Regular Glass: More prone to breaking under impact or extreme temperature changes.


  • Tempered Glass: More expensive due to its enhanced safety and strength features.
  • Regular Glass: More affordable, making it a cost-effective option for many homeowners.


  • Tempered Glass: Ideal for areas where safety and strength are paramount, such as patio doors, bathroom windows, and skylights.
  • Regular Glass: Suitable for standard windows and applications where safety and strength are less of a concern.


Choosing between tempered glass and regular glass for your home window upgrades ultimately depends on your specific needs and budget. If safety, strength, and heat resistance are top priorities, tempered glass is the superior choice. However, if you’re looking for a cost-effective solution with versatility in design, regular glass may be the better option.
