Energy-efficient windows and patio doors are designed to minimize heat transfer, keeping your interior cooler in the summer and warmer in the winter. This translates to a more comfortable living space plus lower energy bills to boot. What makes a window energy-efficient, though? Learn all about this in the FAQ below on energy-efficient windows.
-
What Is a Gas-Filled Window? Most energy-efficient windows have two or more panes of glass. The space in between the panes is filled with an inert gas called argon to act as an insulator to help increase your window’s thermal value and reduce utility costs.
-
What Is Low-E Glass? The “E” in low-E glass stands for emittance. Low-E glass is coated with a clear material that reduces the transmission of UV rays from outside without minimizing the amount of sunlight that gets through. When shopping for replacement windows, look for products with a Low-E coating as this is definitely worth the investment.
-
What Is The U-Factor? U-factor is the rate at which a window, door or skylight conducts non-solar heat flow. To put it simply, U-factor measures the amount of heat that passes through your window. A window with a low U-factor will have a greater resistance to heat flow and will have better insulating properties.
