8 CONCLUSIONS

The viability of the microclimate frame-vitrine depends on successfully sealing the interior air space from the outside air. Minimizing the interior air volume in relation to the panel volume ensures minimal moisture transfer. The seals and backplate needed can be made from a variety of readily available, low-cost materials, thus ensuring the practicality of the design. The use of high-quality glass will be the greatest expense. The development of this vitrine design has resulted in cost savings of 60–70% per vitrine at the Rijksmuseum.
