If you are comparing energy efficient windows for Sumter SC homes, pay close attention to U-factor and SHGC. U-factor shows how much heat escapes or enters through the unit, and SHGC shows how much solar heat the glass lets through.

For most homes, a double-pane window with low-e coating is the minimum worth considering. It is a common setup for good reason, because it helps reduce heat gain without making the house feel dark or closed in.

Compare full frame replacement to insert replacement if the existing frame is in rough shape.

Window replacement vs full frame replacement Sumter SC is not just a technical distinction, because it affects the look, the cost, and how well the new unit performs.
