When it comes to replacement patio doors and windows, today’s homeowners are more conscious about these products’ ENERGY STAR® ratings and consider it to be a must-have feature. After all, this seal verifies that the products use 20% to 30% less energy than their counterparts, which mean more savings on energy bills.
Here at Renewal by Andersen® of Arkansas, we take great pride in providing window products that are designed to be more energy-efficient than standard windows, which mean that they qualify for the ENERGY STAR seal. There are three main factors that determine whether a window can be an ENERGY STAR-rated product:
U-factor – This measures the ease with which heat flows through a window. A window with a lower U-factor means heat transfer is more restricted and has higher insulation properties. The glass we use for our replacement windows can also be used for sliding French doors, delivering the same level of energy savings.
SHGC (Solar Heat Gain Coefficient) – This indicates how much heat from the sun can travel into a home through the window. SHGC is a crucial factor since the sun’s heat is one of the major influencers of indoor temperature levels. A lower number signifies that less solar heat is allowed in, which translates into higher energy efficiency.
Air Leakage Rating (AL) – This is the measurement of how much air can flow through the frame and joints per square foot of window space. It is important because it can determine just how hard your heating and cooling units will have to work just to achieve and maintain your preferred indoor temperatures. Higher air leakage means you’re not keeping indoor heat in and outdoor heat out, making HVAC units work even harder, which leads to higher energy bills.
