Myth-busting, round three. TRUE or FALSE π
1οΈβ£ An insulated garage door automatically keeps a garage noticeably cooler in Arizona summer.
2οΈβ£ If your door is still under manufacturer warranty, every issue is automatically covered.
3οΈβ£ A wider two-car door is structurally weaker than two single doors.
4οΈβ£ Weatherstripping is mostly about looks, not performance.
5οΈβ£ Once a door is properly installed, it never needs realignment.
β
ANSWERS:
1οΈβ£ TRUE, with a catch. Insulation helps reduce heat transfer and can make a real difference, but it's one piece of a system that also depends on weatherstripping and seal condition.
2οΈβ£ FALSE. Most warranties cover manufacturer defects, not wear items or damage from weather, impact, or lack of maintenance. Always worth reading the fine print.
3οΈβ£ FALSE. A properly engineered wide door with correct hardware and reinforcement holds up just fine. Engineering matters more than width alone.
4οΈβ£ FALSE. Good weatherstripping keeps out dust, water, and pests, on top of helping with temperature control. Function first, looks second.
5οΈβ£ FALSE. Hardware settles, tracks shift slightly, and Arizona's heat swings add to that. Periodic realignment is normal, not a sign something went wrong.
