Foam Board

Foam Board

Definition

Foam Board is a lightweight, rigid sheet consisting of a foam core sandwiched between two layers of paper or other facing materials. It is widely used in picture framing, graphic displays, architectural models, and presentation work. Foam board provides structural support for artwork while remaining lightweight and easy to cut, mount, or handle. Archival and acid-free versions are available for conservation purposes, ensuring that artwork is protected from acidity and degradation over time.

Uses

• Mounting prints, photographs, or posters for display or exhibition.
• Acting as a backing board inside picture frames to provide stability and support.
• Serving as a substrate for collage work, signage, or craft projects.
• Used in architectural models and prototyping due to its rigidity and light weight.
• Providing archival-safe support when acid-free foam boards are used in conservation framing.

Best Practices

• Choose acid-free or archival-quality foam board for long-term artwork preservation.
• Cut with a sharp utility knife or precision cutter to prevent tearing or chipping the outer paper layers.
• Use appropriate adhesives or mounting techniques (e.g., dry mounting, hinging) to avoid warping or buckling.
• Avoid exposure to high humidity or moisture, which can cause the foam core to warp or delaminate.
• When used as a backing board in frames, ensure proper sizing to fully support the artwork without gaps.
