A Foam Core Spacer is a sheet or block of foam core material used to elevate artwork, mats, or glazing within a frame, creating visual depth and a shadow effect. It is commonly employed in both traditional and contemporary framing to give artwork a "floating" appearance, separating it from the backing or mat for enhanced dimensionality. Archival-grade, acid-free foam core spacers are preferred for preservation purposes.

Uses

Creating a shadow or layered effect behind artwork or mat borders.
Providing separation between artwork and glazing to prevent adhesion and protect delicate surfaces.
Used in float mounting techniques to make artwork appear to float within the frame.
Adding structural support for lightweight artwork, prints, or photos.
Can be cut to custom sizes to fit unique frame dimensions or mat openings.

Best Practices

Use acid-free or archival foam core to avoid introducing harmful chemicals near artwork.
Ensure the spacer is cut precisely to the size needed for an even, professional appearance.
Combine with proper mounting techniques (e.g., hinging, flexible tabs) to secure artwork safely.
Avoid using spacers that are too thick, which can cause instability or stress on the frame structure.
Position spacers evenly behind the artwork to prevent tilting or uneven shadow effects.
