Four Key Aspects of Code Compliance for Windows

Aside from style and color, building codes are things you need to consider when it comes to windows and doors installation. Building codes aim to address important concerns like public health, safety and environmental protection. 

Here are the four key aspects of code compliance for windows. 

Emergency Escape and Rescue Openings (EERO)

Finished sill heights can’t be over 44 inches above the finished floor. Windows must open at least 20 inches wide or 24 inches high, with no less than 5.7 square feet of total open area. Keep in mind that an opening can’t be both the minimum width and height and still meet the minimum area requirement. In homes built before the implementation of these minimum requirements, the only way to install new windows is to enlarge or lower the opening in the wall. 

Fall Protection

Operable windows with a sill height lower than 24 inches above the floor are required to be more than six feet above the grate outside the window. This is to protect young children from serious injuries after falling through windows with low sills. 

Energy Conservation 

Energy-efficient windows and even sliding doors can help reduce your heating and cooling costs. Replacement windows must meet U-factor and solar heat gain coefficient (SHGC) ratings suitable for the location where they will be installed. 

Safety Glazing 

The International Rescue Committee (IRC) has identified seven locations that are considered hazardous. Your window must be safety glazed if it is placed in one of these areas. A safety glazing can either be a security film or tempered glass.
