Plexiglass is more expensive than glass, and is susceptible to scratching, however it offers some tremendous advantages. Plexiglass will not break during shipping or an accidental fall. It is also much lighter weight than glass, which can be a factor in larger pieces. Most framers do not handle glass over 40” x 60” for safety reasons. Most high-end galleries use plexiglass exclusively because it eliminates the problem of breakage. When glass breaks, it typically scratches the artwork. Plexiglass is also available in non-glare, and with additional UV filtering. It should be noted that standard plexiglass filters 50% to 60% of UV rays.
