They cannot be kept under the sun or exposed to moisture for prolonged hours. it is preferable to use foamboards for temporary outdoor display, otherwise, they tend to get warped, discolored, and disintegrated when exposed to the outside elements.

Foam board is also quite acidic, so avoid mounting archival materials on it because the chemical composition of the plastic will degrade the artifact over time. Lastly, foamboards are known to be fragile, easily dented by a little fall and can be snapped over your knee or punctured with a fingernail. So as much as possible take good care of your foamboards.
