What Usually Gives The Best Return

Will the window actually cut heat gain in the rooms that get the worst sun? Does the frame fit your durability and maintenance expectations? Is the installer familiar with local code, weatherproofing, and moisture control? Are you getting the glass and spacer setup that matches the performance claims? Will the upgrade improve comfort enough to justify the cost?
