What Is Low-E Glass?

Low-E, short for Low-Emissivity, glass are panes that are coated with a material that helps minimize heat or UV transmission. As a result, your windows become more energy-efficient minus the glare from the sun. This means you no longer have to squint or experience extremely warm temperatures when you’re using windows with Low-E glass.

What Is Insulated Glass?

Insulated glass is made up of two glass panes separated by an inert gas, usually argon, filling in the gaps. This gas is used to prevent heat and energy loss, keeping your home energy-efficient and comfortable at the same time. Many homeowners today use these window glasses for their home improvement initiatives due to the savings they provide.

What’s the Difference Between U-Value and R-Value?

R-value is often used when talking about wall and ceiling insulation. Note that this doesn’t translate accurately when it comes to windows and other fenestration products. For windows, U-values are used instead. Simply put, a higher R-value indicates better insulation in walls and ceilings, while lower U-values mean better efficiency of windows in keeping heat and cold out.
