Straight answers
Buying energy-efficient windows
What makes a window custom?
The frame is built to the approved width and height with a selected operation, frame depth, glass package, finish, grid pattern and installation method. Manufacturing limits still apply to every combination.
Is triple-pane always the best option?
Not automatically. Climate, orientation, frame, weight, sound goals, cost and whole-window performance determine whether the upgrade makes sense.
