Types of Picture Frame Glass
Picture frame glass serves several purposes, including protecting artwork or photographs from dust, moisture, and UV rays. There are several different types of glass that can be used for picture frames, each with its own unique properties and benefits.
Regular Glass
Regular glass, also known as float glass, is the most common type of glass used for picture frames. It is made by melting a mixture of sand, soda ash, and other chemicals, which is then poured onto a bed of molten tin and slowly cooled to create a large sheet of glass. Regular glass is relatively inexpensive and widely available, making it a popular choice for budget-conscious consumers.
While regular glass is a good option for protecting artwork from dust and moisture, it does not offer any protection against UV rays. Over time, exposure to sunlight can cause fading and damage to artwork. If you plan to display your framed photos or artwork in a sunny location, it is recommended to choose a different type of glass that offers UV protection.
Non-Glare Glass
Non-glare glass, also known as anti-reflective glass, is designed to minimize reflections and glare. It is achieved by etching one or both sides of the glass, which helps to diffuse light and reduce reflections. Non-glare glass is a great choice for picture frames that will be displayed in bright rooms or under direct lighting, as it allows for better visibility and reduced glare.
Non-glare glass also provides some level of UV protection, although it may not be as effective as other types of glass specifically designed for UV filtering. If your artwork or photographs are valuable or have sentimental value, you may want to consider a higher level of UV protection.
Conservation Glass
Conservation or museum-quality glass is specifically designed to provide the highest level of protection for artwork and photographs. It is made with an advanced coating that blocks up to 97% of UV rays, helping to prevent fading and damage. Conservation glass is also optically coated to enhance clarity and reduce reflections.
This type of glass is recommended for valuable or irreplaceable artwork and photographs, as well as for pieces that will be displayed in direct sunlight or bright areas. Conservation glass is more expensive than regular glass, but the added protection and clarity it provides make it worth the investment.
Plexiglas
Plexiglas, also known as acrylic or acrylic glass, is a lightweight and shatter-resistant alternative to traditional glass. It is made from a clear acrylic polymer that offers excellent clarity and UV protection. Plexiglas is a popular choice for picture frames, especially in situations where safety is a concern, such as in children’s rooms or public spaces.
While Plexiglas is more expensive than regular glass, it offers several advantages. It is lighter and less likely to break than traditional glass, making it easier and safer to handle. Plexiglas is also more resistant to yellowing and aging over time, ensuring that your artwork or photographs remain protected and vibrant for years to come.
Museum Glass
Museum glass, often referred to as museum-grade or conservation-grade glass, is the highest quality glass available for picture frames. It offers the maximum level of UV protection, blocking up to 99% of harmful rays. Museum glass is also coated with an anti-reflective surface, allowing for optimal clarity and minimal glare.
Museum glass is the ideal choice for preserving and protecting valuable or irreplaceable artwork and photographs. It is often used by museums and art galleries to showcase their collections. However, museum glass is more expensive than other types of glass, so it may not be necessary for every framing project.
