To ensure quality, we offer ENERGY STAR®-qualified replacement windows. If you’ve ever wondered why this is an important factor to consider, sit back, relax, and let us show you.
U-Factor
The lower the number you see on the window’s U-Factor, the better. This measures just how well a window can keep heat from escaping from inside the room. As a rule of thumb, look for a window replacement with ratings that range from .20 up to 1.20.
Solar Heat Gain Coefficient
The heat gain coefficient, on the other hand, measures how well a window resists heat gain. This is timely as it is particularly relevant during summer. For homeowners looking to lower cooling costs, look for lower numbers ranging from zero to one so you’ll spend less on cooling.
Visible Transmittance
Visible transmittance is the measure of how effectively a window can light your home’s interior with daylight. Homeowners who prioritize minimizing the use of artificial lighting should look for higher numbers in this regard.
Air Leakage
Lastly, air leakage is the measure of how much air enters a room through a window. For maximum insulation, make sure to look for products with lower grades ranging from .1 to .3. You will experience fewer drafts in your home.
Taking the time to learn about energy ratings can help you make informed decisions. Remember these factors as doing so will come in handy when it’s time to purchase replacement windows.
