Special Material

Finishing material & Base material
The storage system uses materials that are resistant to moisture, and uses the guidelines recently suggested in national and public museums as a basic principle. Performance criteria should be presented clearly and objectively.

Outline

  • The storage system uses materials that are resistant to moisture, and uses the guidelines recently suggested in national and public museums as a basic principle. Performance criteria should be presented clearly and objectively.
  • Environmentally friendly, humidity control, deodorization, anti-mildew, and non-flammability make the environment inside the storage room clean (no formaldehyde emission, excellent humidity control, formaldehyde, ammonia deodorization rate of 95% or more), and It should be able to safely store and manage the stored items by blocking it from external hazards (anti-fungal/non-combustible).
  • It is important to create and manage a storage environment systematically and stably with materials that are applied to the storage of the National Museum as well as the objective performance check. Therefore, we preferentially use those with a number of performances in the publicly trusted National Museum.

Subbase meterial

moisture preventing panel

As a subbase material before installation of the humidity control finishing material, a product with minimal formaldehyde emission is applied.
Materials that physically blockexternal heat, moisture, pollution factors, and harmful factors of concrete from entering the storage.

Exclusive Door of the storage
The storage door must be able to prevent contamination of various outside air from entering the storage, and must be able to stably maintain the internal temperature and humidity environment.

Outline

  • The storage door must be able to prevent contamination of various outside air from entering the storage, and must be able to stably maintain the internal temperature and humidity environment.
  • It should be manufactured to have fire resistance test and airtightness to ensure safe carrying in and out of the storage, and should be able to maintain the temperature inside the storage at 90°C or less for 2 hours or more in case of fire outside.
