What Makes a Window Installation Energy-Code Compliant in Alabama

From the street, a window may seem perfectly serviceable and still fail to meet energy expectations. Meeting code in Alabama takes more than hanging a window in an opening, since the install has to work with the home’s insulation and air barrier.

The basic performance markers homeowners hear about most are U-factor and SHGC, or solar heat gain coefficient. A lower U-factor helps with insulation, and a lower SHGC helps block summer heat. In a climate like this, low-E coatings generally outperform plain glass because they cut solar gain without making the room feel sealed up.

An experienced window installation company can confirm the cause with a quick inspection.

The opening itself needs to be prepared so water does not migrate into the wall and air does not leak around the unit. Even a high-performing window can disappoint if it is installed poorly, particularly in a humid region.
