Monolithic glass is proper term for "single pane" glass. Both terms describe a single piece of glass in a sash frame (the movable part of the window into which the glass is set) There are a number of options but historically, the glass was either 1/8" thick in most residential applications and up to 1/4" thick in commercial applications. Between the fact the original glass may have had imperfections and that it has "moved" over time, it may have an unmistakable "wavy" appearance. Today that appearance is available but comes at a premium.
We can provide any thickness of monolithic float glass (the contemporary manufacturing method) or wavy glass in a varying degrees of distortion. Either float glass or wavy glass can be tempered if necessary.
