How To Read SHGC On Replacement Windows

Choosing The Right SHGC For Florida Homes

For most Florida homes, especially those with strong sun exposure, a lower SHGC is usually the better starting point, but there is no one-size-fits-all answer.

The Questions That Separate A Good Proposal From A Weak One

A salesperson should be able to point to the specification that shows the rating, the U-factor, and the relevant approval documents.

What is the SHGC rating for the exact glass being quoted? Does the product meet the code approvals required for this home? Will the installer manage the permit and inspection paperwork? How will the window perform for both heat control and storm protection? Are there financing or bundle options if the project includes doors too?
