I am new to this industry but I have heard that Schuco are also leading manufacturers of vinyl windows. Anyone have any experience of Schuco ??
Schuco went out of the window business several years ago after leaving a trail of very unhappy homeowners and dealers.
Some of the better windows out there are made by Sunrise, Softlite, Okna and Gorell. A quick Google search for these brands that include where you live should bring up a few dealers.
