Reference tables
Look-up charts built from stable conventions — standard US garage door sizes, installed cost bands by material/type, torsion-spring cycle-life ratings, R-value by construction, opener HP by door weight, common repair cost bands, and wind-load rating zones.
Standard US garage door sizesStandard US garage door sizes (8×7, 9×7, 16×7, 16×8) with square footage, as labeled conventions — behind the cost-by-size and rough-opening tools.Garage door cost bands (installed)Typical installed garage-door cost bands by material/type, as labeled PLANNING bands — a sanity guide behind the door cost tools.Torsion spring cycle-life ratingsHow long 10k / 20k / 30k-cycle torsion springs last by daily use (one open + close = one cycle), as labeled ratings — behind the cycle-life helper.Garage door R-value by constructionTypical R-value bands by 1-/2-/3-layer door construction, as labeled bands — behind the R-value helper and insulation tools.Opener HP by door weightRecommended opener power (½ / ¾ / 1+ HP) by door-weight band, as labeled typicals — behind the opener HP sizing helper and weight estimator.Garage door repair cost bandsTypical spring, cable, track and panel repair cost bands, as labeled PLANNING bands — a sanity guide behind the springs and repair tools.Garage door wind-load rating zonesWind-load / hurricane rating zones (inland, coastal, HVHZ) and what they mean, as a labeled reference — behind the wind-load reference tool.
