Abstract
A roll-up door assembly includes a first curtain, a second curtain, and a side frame. The first curtain and the second curtain can transition between a lowered position and a raised position. The first curtain and the second curtain at least partially define an internal volume in the lowered position. The side frame includes an elongated body defining a hollow interior, a pair of curtain tracks, a heating assembly, and an inlet assembly. The pair of curtain tracks can guide the first curtain and the second curtain between the lowered position and the raised position. The heating assembly can circulate heated air into the internal volume. The inlet assembly can provide fluid commination between the heating assembly and a lower temperature conditioned space such that the heating assembly can circulate air from the lower temperature conditioned space into the internal volume.
