Selecting a matboard for the first time can be challenging when you are not familiar with the terminology. To help make this easier I have updated the Frame Destination website to provide more information about our matting choices. Click on our Mat Board Help Page. We offer the three basic types of mat board: wood pulp, alpha cellulose, and cotton rag. They range in cost and cost and archival capabilities. Wood pulp, otherwise know as paper mat board is the least expensive but only recommended for temporary framing. Alpha cellulose and cotton rag matboards are archival because those materials are naturally inert and acid free. Papermat can be buffered but they will return to being acidic over time.
