What are the most energy efficient windows?
The three most common window types are aluminum, wood and vinyl. Vinyl window styles are proven to be extremely energy efficient and preferred overall due to several factors. They are non-conductive, meaning it’s hard for air to get in or out. They are durable and won’t bend or dent. They are low maintenance, so you won’t have to worry about warped wood or oxidized aluminum. They are affordable and cost quite a bit less than wood. They will last for many years and they can match any look you desire.

What is Low-E window coating?
A Low E window coating is a microscopically thin, virtually invisible, metallic layer that is deposited on the glass surface. Low E coating blocks damaging UV rays from the sun, improving insulation and reducing fading of your carpet and upholstery.

 What is a gas fill?
Instead of filling the space in between glass panes with air, odorless, colorless and non-toxic inert gasses like Argon and Krypton can be used for maximum energy efficiency.

What does U-Factor mean?
Energy Star defines U-Factor as how well the window insulates. It measures the heat transfer through a window. A low U-Factor indicates a greater resistance to heat flow (in and out) and a better insulation value. U-Factor values typically range from 0.25 to 1.25.
