So, you have items that need to be stored safely and securely in a temperature controlled storage unit. Generally, most household items do not require storage in a temperature controlled unit. However, there are some valuable items that require more care, such as computers, wooden items, musical instruments and fragile antiques. These would normally crack or split from constant weather cycling of frozen to hot weather. Your only option would be to store the items in a secure temperature controlled self storage facility.
A huge advantage of a temperature controlled self storage unit that you would benefit from is protection from ambient Connecticut weather. Rain and snow will not penetrate the roof and the storage units are usually built above flood levels. This means that the temperature controlled storage units are a great choice.
Another advantage of a temperature controlled storage unit is that the humidity control can extend the life of dry goods from damage. Too much humidity or extreme dryness can lead to biological contaminants. This includes mold, mildew, dust mites, bacteria and viruses. Having these grow inside of your items will result in rotting of paper and degradation of wood and possibly health issues. Antique furniture is easily damaged in an environment such as a shed or a garage as the humidity and temperature are hard to maintain in such harsh locations. Mold and mildew can also lead to stains on your upholstered furniture, blankets or other related items. This is another great reason to choose temperature controlled storage as you choice for storing documents and weather and humidity sensitive items.
