Eco Doors & Windows say that upgrading to Low-E glass and Argon gas doubles the thermal performance of their doors and windows. Low-E works by allowing ambient heat inside, but the glass reflects the heat back into the room when it tries to escape. Argon gas slows conduction through the double glazed unit.

When it comes to windows, the type of glass you choose is a critical consideration. Experts estimate that 70 percent of energy loss occurs in windows and doors, and that 90 percent of window heat loss occurs through the glass. Low-E glass windows have a microscopically thin coating that is transparent and reflects heat. The coating is even thinner than human hair! The Low-E coatings keep the temperature in your home consistent by reflecting the interior temperatures back inside.

Argon gas is used to increase the energy efficiency and general performance of thermal windows. Air also insulates less effectively than gas fills. Argon is an inexpensive, non-toxic, colourless, and odourless gas that occurs naturally and constitutes less than one percent of Earth's atmosphere.

Thermal windows, also called insulated glass units, or IGU, are either double-pane or triple-pane, meaning each section of window has two or three layers of glass with a sealed space in between. The spaces are filled with Argon or other gasses to slow the transfer of heat through the window. Gases like Argon are preferable to air because air contains moisture that can condense on the inside of the glass units, making the window cloudy.
