The Four Major Aspects of Code Compliance for Windows

There are four major aspects of code compliance that every window installation company should understand: energy performance, safety glazing, fall protection and emergency escape and rescue. The International Residential Code (IRC) requires windows that are installed in any building are up to these standards, so it is important for you as a homeowner to understand these codes to be able to make informed decisions when selecting windows and who will install them for you.

Four Major Aspects of Code Compliance for Windows

Energy Performance

There are two metrics used to measure a window’s energy efficiency: the U-Factor and the Solar Heat Gain Coefficient (SHGC). The U-Factor measures how effective your window insulates. In general, the U-Factor for windows should be in the range of between 0.20 to 1.20. The SGFC, also called “shading”, measures how much of the sun’s heat comes through the window.

Safety Glazing

Some windows may be located in seemingly hazardous areas and will require safety glazing as a precaution. A location may be considered hazardous if the exposed area of a single pane is bigger than 9 square feet, the bottom edge of the window is less than 18 inches above the floor, the top edge of the glazing is more than 36 inches above the floor and if one or more walking surfaces are within 36 inches of the window.

Fall Protection

Fall protection is a provision in the code that prevents small children from climbing over the windowsill. In 2015, the code was amended so all windows must be at least 24 inches from the ground. If your home was built prior to 2015, be sure to check if your existing windows have the minimum height requirement that meets code guidelines.

Emergency Escape and Rescue

The IRC requires that all windows that are installed in any room that could be used as a bedroom be large enough to allow the occupants of the building to escape or for rescue personnel to access in case of emergencies, such as fires and earthquakes. These windows must also be operable without the use of keys or any special knowledge.

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
