A stable and constant surrounding environment is crucial in preserving costly art and antiques from fluctuations in temperature and humidity.

These changes in the environment caused by external factors such as visitors coming in and out, weather changes and heating are a significant concern for museums and exhibitors.

The effect that these changes can have can often be visible through things such as materials cracking or warping. Often the most damaging effects are caused by repeated changes in the environment and as the arts and antiques grow older they become fragile and less able to acclimatize.

As it is important to control the temperature and humidity, it is recommended to keep a rh of between 45% and 55%. To avoid any damage, a humidity system controlled by a humidistat to monitor the environment 24 hours a day should be used.
