U-Factor and SHGC Requirements for Montgomery County Windows

What U-Factor And SHGC Actually Mean For Your Home

When homeowners start comparing replacement windows, the conversation often jumps straight to style, frame material, or price.

SHGC, or solar heat gain coefficient, measures how much solar heat passes through the glass.

They affect how drafty a room feels, how hard the HVAC system works, and whether a new window actually performs better than the old one on paper and in daily use.

The right balance depends on orientation, room use, and how the home is built.

That mix is exactly why window performance has to be balanced instead of one-sided.

Typical U-Factor And SHGC Expectations In Montgomery County
