How to use this research
Ask whether a proposed framing package includes protection for the back of the work. The answer should name a material and explain how it suits the setting. Do not infer that any board creates a sealed climate-controlled enclosure. For an international move, explain both the current room and the destination conditions to the specialist reviewing the package.
