Rental-Friendly AC Optimization & Room Partitioning Kit

A renter needs to make an oversized room 'smaller' to improve the efficiency of an underpowered AC unit, considering rental restrictions and cost. Current curtain solutions are only 'kind of' effective. A specialized kit could include insulated, easy-to-install, and removable room dividers (beyond just curtains) designed to create smaller, sealed zones for AC, potentially incorporating humidity control features and improving overall cooling performance in rented spaces without permanent modifications.
