Materials & Construction

Wayne Dalton's C-20 steel sectional doors feature pre-finished 20-gauge hot-dipped galvanized 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 full view sections; electric operator; and special engineering to meet windload requirements.

*Wayne Dalton uses a calculated door section R-Value for insulated doors.
