Glazing - Glass - Acrylic
Glazing is the term for the glass or acrylic used to cover and protect artwork in a picture frame. Although neither material is perfect for all art framing, both have advantages and disadvantages.
For a deeper look at the difference between glass and acrylic glazing, read our Glass vs. Acrylic article.
The primary purpose of glazing in framing is to protect the work of art from damaging factors such as temperature, moisture, pollutants and touching. Glazing can also offer protection against UV radiation.
Glass has been the traditional material for glazing for many years. Despite its weight and relative fragility, many art lovers still prefer the sheen of genuine picture framing glass. It does have a few advantages over acrylic, in that it is typically less expensive and stiffer, so it will not bow. In addition, glass will not generally build up static charges like acrylic, which can attract dust into the framing package.
Acrylic, including the trade names PLEXIGLAS® and ACRYLITE®, offers clarity of the finest picture frame glazing without the heaviness or breakability of glass. It is a safer alternative, many times more resistant to impact, and easier to handle, making it a great choice for use in children’s rooms, schools, sports arenas, and with irreplaceable artwork.
