Reading The SHGC Number The Right Way

SHGC is the number that tells you how much of the sun’s energy passes through the glass.

That balance is what separates a bright room that stays livable from one that either runs hot or feels overly shaded.

What To Ask Before You Sign A Replacement Contract

Before signing, ask for the actual SHGC number instead of relying on a general energy-saving claim.

A window designed for the southern climate zone is usually a better fit for Brandon than a generic product chosen from a nationwide catalog.

A few practical questions are worth bringing up before ordering: - Will the installation be done as a full-frame or insert replacement?

Those questions matter because a window is only as good as its full system.
