Understanding U-Factor and SHGC for Louisiana Home Windows

What U-Factor Means In A Hot, Humid Climate

Among the ratings on a window label, U-factor is usually the one that tells you the most about heat transfer.

In plain terms, the lower the number, the better the window is at resisting heat flow.

In a climate like this, poor insulating performance can leave rooms feeling sticky even when the AC is running.

U-factor is not the same thing as solar heat gain control, and the two get confused all the time.

For most homes in Mandeville and across St. Tammany Parish, a lower U-factor is usually the safer bet for year-round comfort.

What SHGC Tells You About Sunlight And Heat

If a window faces strong afternoon light, SHGC often shows up in comfort complaints before homeowners even think to check it.

You do not want a window that is so open to solar gain that the house bakes in the afternoon, but you also do not want to overcorrect and end up with a dark, flat feeling inside.
