Sandwich

Sandwich

Overview

Sandwich refers to the consecutive layers of materials that are placed within a picture frame to protect, display, and support artwork. The concept ensures that each component-such as the glazing, mat, artwork, and backing board-is properly arranged to maintain the integrity, presentation, and longevity of the framed piece.

Typical Layers in a Sandwich

• Glazing: Glass, acrylic, or other protective covering that shields the artwork from dust, moisture, and physical damage.
• Mat: Acid-free or decorative mat board that separates the artwork from the glazing, providing visual depth and preventing adhesion.
• Artwork: The focal piece, such as a print, photograph, painting, or textile, positioned within the mat or frame.
• Backing Board: Rigid or semi-rigid support, such as acid-free foam core or museum board, that stabilizes the artwork.
• Mounting Accessories: Items like Tyvek tape, hinges, or corner pockets that secure the artwork within the sandwich without causing damage.

Applications

• Ensures proper spacing and protection between artwork and glazing.
• Provides structural support for fragile or heavy artwork.
• Maintains alignment and prevents warping or shifting within the frame.
• Facilitates preservation framing by incorporating reversible and archival-quality materials.

Best Practices

• Always use acid-free and archival-quality materials in the sandwich to prevent deterioration.
• Avoid direct contact between artwork and glazing by using mats or spacers.
• Check for even layering and alignment before closing the frame.
• Consider environmental factors like humidity and light exposure when selecting materials.
