If you’re considering a new patio door or front door, you might be thinking about how to optimize its performance. The right glass can help with energy efficiency, noise reduction, and can even provide return on investment. But the right glass choice depends on your home, your climate, and other factors unique to your situation. Not to worry! We’re here to explain how to weigh these considerations and decide between double-pane and triple-pane glass for your new French door, sliding door, or entry door.

Triple-pane glass improves your door’s performance in the following ways:

1. Energy efficiency is improved with triple-pane glass

This is due to the two air spaces filled with an argon-gas blend and the opportunity for multiple Low-E coatings. These features improve the insulating abilities of triple-pane when compared to double-pane glass. This level of performance is most needed in Northern climates, especially if there’s a desire to meet progressive energy requirements or build a high-performance home.

2. Noise is reduced by triple-pane glass

This is because of its thickness. When sound waves have to travel through multiple glass panes and multiple air spaces, they're slowed and effectively reduced. Triple-pane glass could be worth considering if you live near an airport, highway, etc.

The change from double-pane glass to triple-pane glass can increase a door’s weight by 1 ½ times. Our doors with triple-pane glass include framing and components like hinges, sliding mechanisms, and rollers that are designed to perform properly, even with a weightier piece of glass.

When it comes to installation, the weight of the door might necessitate an extra pair of hands or rental equipment, which could increase labor costs.
