Our picture frames and shadow boxes feature frame grade acrylic. We use acrylic instead of glass for many benefits. For one, acrylic is much more shatter-resistant. Frames featuring acrylic glazing are also much more lightweight. In addition to those points, acrylic is less expensive than glass to pass through those savings to our customers. There are two options when it comes to the acrylic we offer for picture frames. The first is a standard frame grade acrylic with UV protection properties. The UV protection will help preserve and protect your images and art from light damage. The second option is a non-glare frame grade acrylic. This is a great option for hanging artwork near a light source to cut down on, and in most cases, eliminate glare. Non-glare acrylic has a cloudy appearance when it's in a frame, but against artwork and/or matting, the cloudiness disappears, leaving you with a crisp, glare-free view of your image or artwork. For this reason, we do not offer non-glare acrylic as an option for shadow boxes.
