If a door will face direct afternoon sun, the frame’s ability to stay stable and keep its seal matters as much as its appearance.

For most homes, insulated glass with quality spacers and tight perimeter seals does more useful work than decorative upgrades that do not affect performance.

• Low-E insulated glass that helps control summer heat and winter loss
• Multi-point locking with tighter compression seals around the sash
• A thermally broken or non-metallic frame design where possible
• A sill and threshold designed to drain water instead of holding it
• Hardware that keeps the door aligned after repeated seasonal expansion and contraction
