In the shower door industry, framing refers to the presence of metal on individual panels of glass, not whether or not there is metal on the outer perimeter of the shower enclosure as a whole. This, understandably, causes confusion among customers who aren’t familiar with the industry jargon.
In short, framed shower doors consist of glass panels that are individually framed in metal, sliding or swinging within additional metal wall jambs and channel to create a finished shower enclosure.
