I am working with an artist who has 48x72" "glossy" photos

In the past he has used non-glare plexi on smaller pcs 24x30.

He would like to use this for the 48x72 photos with no spacer.

any opinions?

thanks

Fine by me. If people insist on working with such large sizes, then they have a choice -- spend the money to do it according to conservation standards, or cut corners.
 
also...i can only find ng plexi in .125 thickness

at 48x72" this doesn't seem thick enough

At that size, a spacer wouldn't do much good anyway. Unless you find NG thicker than .118", the acrylic could flex as much as 1" (or possibly more) in the middle.

I'm sure that it will be in a non-windy environment, but without rigid back support it might just pop out of the frame with a good gust of wind (or if someone pushes against it).

For sure use a rigid back and I would use a 1/2 width rabbet and a strainer with cross braces.

How will the photo be mounted? If hinged, I would use a spacer for at least 1/2" separation, and 3/4" spacing would be better. If this is a standard process photo, pressing any glazing against it may cause problems. The photo could stick if any moisture condenses inside and softens the surface. That's less likely with acrylic, but still possible.

Instead of non-glare acrylic, consider using Museum Optium Acrylic. Its added cost may be reasonable, as a percentage of the total framing job, and it is available in 6 mm thickness; much better for the purpose.
 
if the photos are hinged with no spacer. what are the potential problems other than the possiblity of condensation?
 
Sticking caused by condensation may be the most obvious potential problem, and that would be most visibly destructive. But pressing the photo against the glazing could inhibit its normal expansion and contraction cycles, causing waves or wrinkles. Also, evidence of abrasion would eventually show up.
