Foam Core Spacer

Foam Core Spacer

Definition

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.
