The area sits in a cold, severe winter climate zone, and a door built around 2007 to the minimum code of that year wasn't speccing for today's energy expectations. On an 8,635-household town like Kuna, that means a meaningful share of garages are original builder doors nearing twenty years old, right at the point where the foam core has started pulling away from the steel skin and the seal at the floor has hardened and cracked.
That combination - older insulation standard plus genuine cold - is why a straight panel swap without reconsidering insulation level often disappoints. A new door hung to match the old one's spec just repeats the same shortfall for another fifteen years. The households in this area with the income to choose a better door ($93,545 median, above the service area's $75,270) are usually better served upgrading the insulation tier at install time, not just replacing like-for-like.
