Some people also refer to the mounting board as the foam board. The mounting board typically denotes the back of the frame. It is section to which many canvas mounting and framing professionals attach the artwork. Some people often select cardboard as the mounting board for their frames. But this is an unwise choice. This is because cardboard typically has high acidic levels. As a result, it will cause the artwork to turn yellow very quickly.
Instead of cardboard, it is better to select high-quality mounting boards made from other materials. Some of the top residential and corporate framing companies typically use mounting boards that feature polystyrene cores. In many cases, these polystyrene cores lie tightly bonded between two paper covers. These kind of mounting boards will usually have smooth surfaces. In addition, they will cut cleanly and resist warping as well.
In many cases, you will come across the following kinds of mounting boards:
- Standard Mounting Boards: These refer to the standard 1/8-inch foam boards. These usually have small amounts of wood pulp acid. Suppliers of these boards tend to keep the acidity of these boards as low as possible. Therefore, you can use these for many framing projects.
- Acid-Free Mounting Boards: Many framing companies use these mounting boards because they are totally acid-free. These boards are useful if you want to frame art pieces that have a significant value. These boards can help in the preservation of your valuable artwork for many decades.
- Mounting Boards with Self-Adhesive Sides: These boards come with self-adhesive sides. Many picture and custom mirror framing professionals usually affix the picture permanently to this side. When used for posters or digital frames, these mounting boards are ideal. However, avoid using these boards for valuable art pieces. This is because separating the adhesive backing from the picture afterwards can be quite impossible.
