SWISCO - The Replacement Hardware Authority

UA value and SHGC value of Binnings Windows.

A quick learner from Raleigh, NC says:
You have helped us with replacement parts for these windows a couple of times. Currently, we are desperate to find the UA value and SHGC value of these windows which were installed in 1999 here in Raleigh. We have not been able to locate anyone from Binnings who can help us. Do you have any idea where we could obtain this information???

Hello! Hopefully we can help. 2003 Binnings window manufacturer was acquired by PGT window manufacturing company. No one there was able to help in the U-factor value for windows back in 1999. What I was able to find for Binnings standard double hung window was the following: for clear insulated glass, the U-factor was at .48 and the SHGC was at .62. For LoE insulated glass, the U-factor was .34 and the SHGC was at .27. I hope this helps you.

Paul,
Thank you for the information. Would the ratings be the same for a single hung window? How could I tell if it is a LoE glass? Thank you . . .

I believe that single hung windows might have a slightly better rating because the top sash is fixed. With the top sash fixed, no air can escape around the top of the window like it would if you had a movable top sash. Look at the window from the outside of the house. If you do have LoE glass, it will have a somewhat tinted look, almost like a mirror, when the sun hits it.
