Do floater frames have glass?

No. Floater frames are not classic picture frames or clip frames. They have neither a glass pane nor a closing back panel and are therefore not suitable for framing posters or photos. Instead, they are used to frame stretched canvases and canvas pictures. The canvas is placed in the floater frame and screwed in from the back.

PS: Panel pictures on Dibond, Forex or wood also look great in floater frames.
