Would like to update my previous review – the Soft-Lite Imperial LS is an attractive window, though I do not like the somewhat “sloppy” diagonal corner welds on the sashes. But you don’t notice it unless you are looking closely. The fiberglass screens are more reflective than our old aluminum ones and block the view more in strong sunlight. But I like that they can be raised to the top sash level and will stay in place, allowing the top sash to be lowered for air flow. Soft-Lite does not offer outside-the-glass simulated divided lights that look real, as I saw on a Pella wood window – would have liked that option. The locks on several of my windows are a little difficult to open/close, not sure if that is a Soft-Lite, installation, or “user” flaw. The windows themselves open and close easily. As this is a new installation I cannot yet comment on energy efficiency.
