Dry Mounting

Dry mounting is a permanent mounting process where the art is glued to a mounting board, using heat and pressure. The mounting board is usually a foam core board, but other boards can be used 

A tissue-type adhesive is placed between the art and the mounting board. This combination is then inserted into a vacuum press and heated up to activate the adhesive while the press applies pressure. Fabric, such as canvas, or silk, may also be mounted on boards to create backgrounds or mats. 
If a piece of art is to be conservation framed then dry mounting cannot be used, since it would adversely affect the value of the art.  

An inexpensive replaceable movie poster, art poster or music poster would be good examples of items that would be dry mounted.
