Upward acting sectional doors are very similar to the garage door on your house. The difference being, they are built for commercial and industrial applications. They also come in a wider variety of sizes including doors as wide as 30 to 40 feet depending on the manufacturer.
These doors are available in non-insulated and insulated sections. The sections are available in a variety of widths depending on the application. The sections travel in 2 inch or 3 inch track using rollers attached to the sections. The size of the track is determined by the application for the door.
Upward acting sectional doors can be push up, chain hoist, trolley motor operators or side mounted jackshaft operators. Frequency of usage and door size is a determining factor in selecting a means of operation.
Insulated sections can be filled with laid-in-place polystyrene or foam-in-place polyurethane insulation. R-Values can be in the 20’s depending on section thickness and the type of insulation used.
