Energy-Efficient Glass Upgrades for Existing Windows

Many older insulated windows still have frames and operating components that are in good condition, even though the original glass may no longer provide the level of energy performance available from modern glass technology.

In these situations, complete window replacement may not be necessary.

WindowFixGuru™ can replace eligible insulated glass units with modern Low-E energy-efficient glass, allowing you to improve window performance without removing an otherwise functional window system.

What Is Low-E Glass?

Low-E glass contains a very thin, nearly invisible coating designed to help control the transfer of heat through the glass. During colder weather, Low-E glass can help reduce heat loss through windows. During warmer weather, it can help reduce unwanted heat transfer into the building.

This allows modern insulated glass units to provide better year-round performance than many older standard glass systems. The important advantage is that Low-E glass can often be installed as part of a replacement insulated glass unit without replacing the entire window frame.

Benefits of Low-E Glass

Upgrading older insulated glass units to Low-E glass can provide several advantages for both residential and commercial properties.

Low-E glass can be particularly beneficial in rooms with large windows, significant sun exposure, or areas where indoor temperatures are difficult to maintain.

When Is a Low-E Glass Upgrade Recommended?

A Low-E upgrade can be considered whenever insulated glass is being replaced or when property owners want to improve the efficiency of existing windows.
