Vinylite windows

Vinyl windows are almost all the same.

Mine are fine, but after getting them I wished I had wood.

The biggest downside is the 3" all around the window opening for that tacky vinyl.

Just because they are Low E Argon doesn`t mean didly. There are many different performance perameters windows are rated for. Such as cdf , shg, vlt, r value etc.

Read Consumer Reports to start the learning experiance. Glass is not Glass as Bs salesmen will tell you. But evolving and not equal.

This information is incorrect.

There's virgin vinyl, and recycled vinyl. Also, it matters a great deal of the amount of cavities in the frame and sashes. Cheaply made vinyl windows are always very large frames like yours, and not as rigid. A slimline vinyl has extra cavities and made from virgin vinyl, the frames are less than half the size of yours (1-1/4"). Sounds like you have recycled cheap windows.
