When should I choose glass or acrylic to cover my artwork?

Most people are familiar with the use of moulding and matting when it comes to custom framing, however, many are unaware of the importance of glazing when it comes to the protection and beauty of their framed piece. This is understandable as you might even ask yourself, what is “glazing”? Glazing is the protective covering used in picture framing – it refers to either acrylic or glass. It’s understandable when people wonder if they should cover their artwork with glass, acrylic or nothing at all.


The glazing you choose can be extremely important as glazing will help protect your cherished artwork, family photos, or any object you wish to have framed. We know that when you come to SF Framing to custom frame, it is because the piece you are framing is important to you, and the project you bring to us is something you want to enjoy for a long time to come. The following are our recommendations for you:


We generally do not recommend glazing over oils, acrylic and giclee paintings.


Acrylic is preferable for the majority of artwork. It is both lighter than glass and shatterproof – important factors to consider in regions plagued with earthquakes and for pieces larger than 36 inches x 48 inches. An exception is pastels, since acrylic’s static charge can attract fine chalk particles from the artwork. In this case, glass is often substituted.


Whether you choose glass or acrylic glazing, when you have something that you want to preserve from the effects of damaging ultraviolet (UV) light, we recommend the glazing material chosen be treated with a special coating to keep out damaging UV light. This is often called “Museum” acrylic or glass – which is more expensive than standard acrylic or glass. A new economical anti-reflective, UV protective glass is now available from SF Framing to help reduce the cost of preserving your piece.


Always ask your SF Framing design consultant about the best glazing choices available for your treasured artwork.
