In a True Divided Light window, each window pane is a separate piece of glass. The glass is referred to as a “light”. The “lights” or individual panes of glass are held in place with a Muntin – a thinner piece of wood dividing the lights – similar to the tick-tack-toe pattern.
Windows with true divided lights sparkle when viewed from the street. If the glass is older and wavy, they sparkle even more.
Since muntins are made of wood, they provide a small shadow line on the glass pane. This makes the window pop with life and character, and changes with interest as the sun travels and the lighting changes.
We recommend both True Divided Light and muntins to our clients. Muntins can be a more cost effective option than a True Divided Light.
Some replacement windows, instead, offer one piece of glass with a flat plastic grill attached on the interior to imitate the look of window panes separated by muntins. The result is a very shallow, flat, and bland, not to mention cheap, appearance. It appears as if it were painted on the glass. Better options exist such as grills on the exterior and interior etc. Fake window grills on both the exterior and interior must have a spacer in between to give the appearance of real muntins. Buyer beware! PORTALS does not recommend cheap plastic products be installed in association with wood windows. are still not true divided light windows.
