Temperature Controlled Storage Benefits

Temperature controlled storage units are kept between 12C (55F) and 29C (85F). There are many benefits of choosing between temperature-controlled storage and standard storage:

  • Protection from more extreme temperatures. The temperature in standard storage units can reach above 38C (100F) in the months of summer, dropping drastically in the winter months. Such fluctuations can make sensitive materials warp, split/crack, yellow and degrade.
  • It may be more expensive to replace an item, rather than storing it.
  • Visit your self-storage unit at a comfortable temperature and with privacy since all interior units do not require driving up to load directly from a vehicle.
  • You do not have to concern yourself with pests, temperature damage or corrosion more typical of exterior units.
  • Flooding and water exposure that stems from humidity, rain or melted snow are not of concern due to them being enclosed in a building.
  • There is little to no dust and dirt that gets into interior units compared with basic storage areas.

We recommend storing the following items in temperature controlled units:

  • Wood furniture and antiques
  • Instruments
  • Bedding and mattresses
  • Old magazines and books
  • All electronics
  • Valued business and personal documents
  • Art and photos
  • Upholstered furniture, leather and clothing
  • Vinyl records
