Framed oil canvas with glass

[AtelierFrames]

Hi
A customer has requested a number of oil paintings on stretched canvas to be framed under glass. I have explained they would need a spacer or slip frame so that the painting does not come into contact with the glass . However, would I put a backing board on the back or leave this open for the canvas to breath.

Thanks

"Canvas doesn't breathe!" is a common exclamation on other forums.
As I understand it, it is common practice in the US to back a canvas with a corrugated polyproplene board, but not common in the UK. Personally I like the idea but would take my lead from someone like Tudor Rose.
I can say however that when framing a canvas it is advised to use Acrylic rather than glass, due to the high likelihood of costly damage to the canvas should the glass break.

Thanks for the prompt response. I will check out the other threads on yhe forum as you suggest.

Also, a valid point about potential damage to canvas should the glass break.

Your feedback is very much appreciated.

"...on other forums.." was referring to Framers Only/framing.academy groups etc on facebook.
