What U-Factor and SHGC Mean for Montgomery County Windows

How These Ratings Shape Real-World Window Performance

Anyone comparing windows in Montgomery County will run into two ratings right away, U-factor and SHGC. They are not there just to make a brochure look technical.

U-factor tells you how much heat escapes through the whole window assembly. A lower SHGC means less solar heat comes inside.

That is why an experienced window replacement company can confirm the right balance of U-factor and SHGC with a quick inspection.

How To Read The Ratings Without Getting Lost In The Details

In plain terms, homeowners want a window that slows heat transfer as much as possible without creating other problems. Two windows with the same number of panes can still perform very differently because of coatings, gas fills, and frame material.
