In most circumstances, it is not necessary to cover a canvas work with glass or acrylic, but there are some circumstances where it is appropriate. If you do wish to cover and don’t wish to use a liner border we can put spacers on the outer edges of the glass/acrylic to prevent it from having direct contact with the artwork.
Typically our clients use either Ultraviolet Filtering Acrylic (UFA) or Optium Museum Acrylic (OMA). Both protect against color fading and other pollutants such as dust, whilst acrylic won’t shatter like glass and is significantly lighter. OMA is a higher price than UFA, but offers 99% UV filtration, scuff resistance, anti-static protection, and still remains almost crystal clear vs. many other options in the market.
