If your home’s windows are outdated, you may literally be throwing money out the window. According to the U.S Office of Energy Efficiency and Renewable Energy, heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use. High-quality, energy-efficient windows will save you money and keep you and your family comfortable all season long.

How energy-efficient windows save you money.

When purchasing windows, be sure to look for the Energy Star label. Homeowners who who install Energy Star windows save an average of 12 percent on their utility costs each year. Below are the features that together, can add up to some big energy savings: 

GLASS SHEETS:  Today’s energy-efficient windows are constructed with multiple sheets of glass sandwiched together with spaces. Air pockets, which are created between the layers of glass, are sealed shut to prevent any air from entering or escaping. 

GASES:  For added efficiency, the air pockets are filled with odorless and non-toxic gases like argon or krypton, which act as an additional barrier between your home and the outside elements. 

LOW-E COATING:  A low-emission coating on the glass traps the sunlight that passes through, keeping your home warm during the cold weather months. 

FRAME:  The window frame material and construction also has an impact on the overall efficiency of the window. Non-metal, thermally-improved frames perform the best. 

INSULATION: windows must be installed to manufacturers’ specifications and properly insulated. Spray foam is recommended and must be correctly applied as the windows are installed.

Energy-efficient windows provide peace and quiet.

With energy-efficient windows, the same insulating qualities that reduce heat loss also help keep sounds out. This is great for those of us who live close to the street or in busy neighborhoods. 

The Importance of Proper Window Installation

A window can only perform well if properly installed. Quality installation is critical for an airtight fit and a continuous water barrier to prevent drafts, water damage, and condensation. The complexity of the installation depends on whether you are considering complete window replacement or inserting windows or sash kits within the existing frame. Make sure to follow manufacturers' recommendations on whether the particular installation requires trained professionals or whether do-it-yourself is an option.
