Defrosting roll-up climate controlled door

A roll-up door assembly, comprising:

• (a) a pair of curtains configured to transition between a lowered position and a raised position, wherein the pair of curtains at least partially define an internal volume in the lowered position;
• and
• (b) a side frame, wherein the side frame comprises:
• an elongated body defining a hollow interior,
• (ii) a pair of curtain tracks configured to guide the pair of curtains between the lowered position and the raised position,
• (iii) a heating assembly configured to circulate heated air into the internal volume,
• (iv) a sensor located within the internal volume, wherein the sensor is configured to generate a signal, and
• (v) a control module configured to generate an instruction in response to the sensor generating the signal, wherein the heating assembly is configured to adjust a ratio of air originating from a lower temperature conditioned space and the internal volume in response to the instruction generated by the control module.
