High-speed door
Short definitionA PVC door that opens and closes in seconds. It reduces air infiltration where traffic is frequent.
A door that forklifts go in and out of all day cannot be opened and closed every time with a heavy insulated leaf, and it usually ends up left open. A high-speed door opens as the vehicle approaches and closes once it has passed.
Its insulation value is not as good as a panel door. So it is usually used together with an insulated door: the insulated door is closed at night and the high-speed door works during the day.
