Materials & Construction
Wayne Dalton's C-2400 steel sectional doors feature pre-finished interior and exterior skins on nominal 24-gauge hot-dipped galvanized steel sections roll-formed to a full 2" thickness for ultimate strength and durability. The 3" wide fully-fitted boxed stiles are adhered with adhesive, preventing rust and leakage associated with rivets. Standard bottom door seal along with optional seals on the perimeter and between sections greatly reduce air leakage, adding to the thermal efficiency of the building.
Additional options include insulation and weather stripping that provide a U-value of 0.13 and an R-value of 7.60; factory installed vision lites or aluminum full view sections; and special engineering to meet wind load requirements.
*Wayne Dalton uses a calculated door section R-Value for insulated doors.
