Plastic Spacer
Plastic Spacer is a protective component used in picture framing to create a physical separation between the glass (or acrylic) and the surface of artwork, preventing direct contact that could cause sticking, abrasion, or moisture-related damage. Plastic spacers are commonly used in conservation framing and display settings where maintaining the integrity of the artwork is essential.
Materials and Construction
- Plastic Composition: Typically made from durable, non-reactive plastics such as polyethylene or polypropylene, which are lightweight, archival-safe, and resistant to warping.
- Design: Available in U-channel, L-channel, or strip forms to fit snugly along the perimeter of glass or acrylic sheets.
- Dimensions: Thickness and width vary depending on the depth required to protect the artwork from the glazing surface.
Functions and Applications
- Artwork Protection: Prevents the glass from sticking to or pressing against artwork, especially for delicate media like pastels, watercolors, or textiles.
- Conservation Framing: Maintains a micro-environment around the artwork, reducing risk of humidity damage and off-gassing from glazing materials.
- Structural Support: Keeps glass evenly spaced from mats or mounts to prevent bending or bowing.
- Adaptability: Works with various glazing types including regular glass, non-glare glass, and acrylic sheets.
Installation Considerations
- Spacers should be cut or selected to match the dimensions of the artwork and frame.
- Ensure even placement along all edges to avoid tilting or pressure points on the artwork.
- Plastic spacers should be non-yellowing and free of harmful additives to preserve the longevity of the framed piece.
