Sears weatherbeater windows at one point in time were a product manufactured by Simonton windows. I have heard from ex Sears associates that the Windows are it's own brand now. While Simonton is arguably the best brand in Windows, Sears would rebrand the product and hide the prestigious Simonton name so prices could not be compared with competitors such as Lowe's or home depot. Cliche isn't it? This is what they do for many of their name brand products.
