Take a Closer Look at Mezzo’s Triple-Pane, Ultra Efficient Glass System
Further increase the energy efficiency of your Mezzo Windows with triple-pane glass protection. This high-performance design features a 1″ thick (nominal) glass unit, three panes of glass, two surfaces of Low-E (low- emissivity) technology and two spaces of argon gas, along with the ClimaTech ThermD Stainless Steel Intercept Spacer for a powerful energy-saving shield. You’ll also appreciate the improved overall comfort and quieter indoor ambiance of your home.
Insulated Glass Packages
Reducing energy loss is often the number one reason for purchasing replacement windows. Windows are roughly 80% glass, so it’s important to choose the ideal glass system for your home and climate. Upgrading to a high-performance Low-E (low-emissivity) insulated glass package may help further increase year-round energy savings.
Mezzo offers four families of high-performance insulated glass packages, including our innovative ClimaTech PriME insulated glass package, which meets ENERGY STAR Most Efficient in all climate zones:
| ClimaTech PriME – Combines three panes of glass, three surfaces of Low-E (low-emissivity) technology, two spaces of argon gas fill and two warm-edge spacer systems. |  |
ClimaTech – combines insulating Low-E glass, argon gas and the Intercept Warm-Edge Spacer System.
ClimaTech ThermD – features insulating Low-E glass, argon gas and a Stainless Steel Intercept Warm-Edge Spacer System.
ClimaTech Plus – combines our Foam Spacer System with a glass unit of UV-filtering Low-E (low-emissivity) glass and argon gas.
