In the self storage world, climate control refers to keeping storage units within constant temperature ranges.
This helps protect your items from extreme temperatures and humidity.
These units are insulated against external temperatures, making it so that your items are safer year-round.
Not every item demands climate control, but all fare better in the long term. Some items, however, are especially prone to damage from extreme temperatures or humidity.
Because the internal temperature of storage units without climate control can be dozens of degrees higher than the temperature outside, this is especially dangerous for property sensitive to heat damage.
Wood can start to split. Metal might begin to corrode. Plastic can melt. Humidity can cause mold and mildew to form in fabrics and upholstery.
