FAQ
Frequently Asked Questions
Yes, in many contexts they are synonyms, particularly in American English. 'Muntin' is slightly more general, while 'sash bar' specifically relates to a sash window.
Yes. Historically, they were primarily wood, but modern and specialised windows can have sash bars made from metal (e.g., steel, aluminium), vinyl, or even reinforced fibreglass.
Less so, as modern windows often feature large, single panes of glass (picture windows) or simulated divided lites (SDLs) where the 'bar' is just an aesthetic overlay. The term is most relevant for traditional, multi-pane windows and their restoration.
A chisel, rebate plane, and sash fillister plane are traditional woodworking tools for shaping wooden sash bars. Modern work might use table saws and routers.
