The Question posed is important. Why are people paying almost double for a product and not getting double the value. We addressed the major design issues of thermal performance, air infiltration and balance systems. The Andersen Renewal product is a good window but for the money you would get a whole lot more from the Soft-lite Imperial LS. By selecting the Imperial LS window with Ultimate glass, you will have a window that has almost twice the thermal performance, 15 times less air infiltration, Comfort-Foam filled cavities, Kevlar reinforcement, anti-bacterial weather stripping, superior balance systems and internal parts, coupled with one the industries best warranties.
A better window for less money!
Now this is a winning combination!
