We would like to replace our 1985 aluminum windows, 4 sliders, 4 double hung (2 of which we would like to make a picture window), 2 lg trapezoids, 1 sidelite, 1 transom and 3 patio doors. We live in the southeast and have had 4 quotes already from $9,000 to $14,000 for 4 different products. I am on window overload, I read all 67 pages here on the forum and found it to be informative. Does anyone have experience with these two products that we have narrowed it down to - Soft-lite, Elements with dual pane argon with LowE and the Preservation triple pane with argon with LowE. They all have references and are good solid companies. We appreciate any help. Thank you.
