Humidity Control • Airtightness • Volatile Organic Compounds



The humidity level in the showcase should follow the conservation requirements for the object. The required humidity level can be achieved through a passive approach by using silica gel. Passive climate control relies on the natural circulation of air within a case. The silica gel cassettes are placed in a compartment underneath the showcase and are accessible via a removable plinth.

Alternatively, you can consider an active approach by using an automatic device.
Which solution is best suited for your particular situation depends on the artifacts themselves and the environment. We are happy to advise on a suitable solution.

Air tightness

The Air Exchange Rate (AER) expresses the amount (%) of air renewal over one day. An AER of 0.1 means that 10% of the air is being renewed per day. What AER is appropriate for your situation, depends on the conservation requirements of the object.

During the quality control at the end of the assembly, an AER test is performed on each case.


Volatile Organic Compounds (VOC) are harmful molecules that can be found in some materials and finishes such as wood, sealants, or paint. In order to keep the level of VOCs below the international standards, each material and finish is tested by an independent laboratory. Additionally, materials and finishes can be tested using the ODDY method. For more information, contact our experts.
