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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
