Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

In many cases, window tinting will boost your home value. If you’re selling your home, especially in a warmer climate, buyers are very likely to see immense value in window tinting, which improves the home’s energy efficiency and helps make the living space more comfortable. Buyers may also recognize the privacy and security improvements offered by window tinting, which could lead to them paying more for your home.

Visibility through tinted house windows or privacy film depends on the lighting. During the day, the tint or film typically prevents people from seeing inside. However, at night, if you have lights on inside your home, the interior will be brighter than the outside, which allows people to see in. You can choose from various shades of privacy film, from lighter to darker, to optimize the level of privacy you want.
