I second reviewing the AAM Sustainable Exhibition toolkit for its overview of flooring materials. See the footnote regarding rubber flooring. We avoid vulcanized rubber products around special collections storage, and when possible exhibited materials, as rubber flooring and wall bases offgass their sulphur components that can degrade certain collection materials, especially photographs/negatives. Additionally, the AIC lists rubber and rubber derivatives as unacceptable for exhibit case construction. Let me know if you have questions. Best, Michele
