Hardware and installation are easy to overlook, but they make a real difference.

A few performance details deserve attention when comparing options:

• Low-E coatings that help control glare, heat, and energy loss
• Multiple panes that improve thermal performance compared with single-pane units
• Warm-edge spacers that reduce condensation at the glass edge
• Tight weatherstripping and a durable sill design
• Frame construction that performs better in seasonal extremes
