We had 15 Atrium replacement windows installed in our home. Wouldn't waste your money!! The first set of windows that were delivered and installed, grill work inside windows were all bent. All windows needed to be replaced, out of the 2nd set we received 4 were still unexpectable. On the 3rd try we finally had grill work straight inside. Very hard to open, I can't even open my window over the kitchen sink without almost standing on the counter. Screens are also very hard to put back on, I like to have screens off for the winter, I can't even get them on my husband has to do. I'll have to hire someone as I age just to put the screens back on. WORST INVESTMENT EVER!!
