Tempered glass is no less energy efficient than regular glass, especially when you go with a C5 Window from Conservation Construction. That’s because we still use all the same extraordinary coating on the glass that makes it energy efficient. We use Neat Glass, LoE-366 Glass Coatings, and Krypton/Argon Gas mixture to ensure lifelong energy efficiency and insulation for the window. On top of this, you’ll get vinyl frame which are foam filled to ensure better strength against air infiltration.
Tempered glass prevents breaks, cracking and everything else in between. It is multiple times stronger than regular glass which prevents it from turning into jagged shards on the floor when guests exit and enter your home. Not to mention tempered glass is about 3x more expensive than regular window glass so you wouldn’t want it in your entire home or you’d be spending a lot more money.
