As the chill starts to roll in... the side walls go up and the tent heaters get pumping. Chicago Tent, LLC. Rentals and Sales can not only provide shelter from above, but we can wrap your tent up with sidewalls like a blanket and tent heaters like a cozy fireplace. Side walls not only block the wind, but they contain body heat and the warmth provided by tent heaters. Our climate controlled tents can provide a comfortable setting through the cold for Fall events and winter parties.
