The 4300 and the 4301 are Premium Series doors: steel + insulation + steel. Clopay's Premium Series offers discerning homeowners an elegant yet affordable combination. These models offer 2" of polystyrene insulation pressure-bonded two steel "skins," creating a three layer door that delivers unparalleled strength and beauty. For homeowners with rooms above or adjacent to the garage, these doors provide quieter operation and offer greater insulation from weather conditions than any other doors. These doors are available in elegant raised panel design and flush woodgrain design.
