Spacer

Spacer

Overview

A spacer is a framing material used to create separation or depth between layers in a picture frame package. Spacers serve functional and aesthetic purposes, such as preventing direct contact between glazing and artwork, or adding dimension by elevating mats or sinking artwork beneath multiple layers. They may be made from foam core, plastic, wood, or specialty archival materials, depending on the application.

Types of Spacers

• Glass Spacers: Plastic or acrylic strips that sit along the rabbet edge of the frame to separate glazing from artwork.
• Foam Core Spacers: Strips of foam core cut and inserted to raise mats or create recessed areas for floating or sink-mounted art.
• Plastic Spacers: Durable and transparent materials, often used in conservation framing, to provide unobtrusive spacing.
• Custom Spacers: Handcrafted or wood spacers used in shadow boxes or to complement moulding styles.

Applications in Framing

• Protects artwork by ensuring glazing does not touch delicate surfaces such as paintings, photographs, or pastels.
• Used to build depth in shadow box frames or deep frame assemblies.
• Enhances visual impact by creating recessed or elevated matting effects.
• Provides flexibility in designing float mounts, layered displays, or three-dimensional presentations.

Conservation Concerns

• Archival-quality spacers should be used for preservation framing to prevent chemical transfer to the artwork.
• Improperly cut spacers may shift over time, causing pressure points on mats or glazing.
• Non-archival adhesives used to secure spacers can off-gas and affect long-term preservation.
