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.
Consult your window professional for the energy-efficient glass packages available for your home and climate zone.
