Last night, on our way to a late-night snack at Atomic Cowboy in "The Grove," we happened upon a set of old doors in an alley off of Taylor Avenue. One of the doors was in great shape, and I loaded it into our truck. The other one was a fancy interior door, with twelve divided lights paired in two columns (this type is often called a "French" door). But I immediately noticed that the bottom four lights were missing their muntin dividers, and were replaced by a single pane of glass with thin firring strips nailed behind to simulate the look of the missing muntins.
It's one thing to look at a brand new factory-made window sash or door, and see flat simulated dividers tacked over a solid pane. The simulation never can replicate the depth of dividers on an authentic wooden sash or door.
It's another thing to see real dividers side by side with cheap replication on one old door. This really shows how ridiculous simulated dividers are, and how far from the authentic divider (a real muntin) they are.
Needless to say, we left the second door in the alley.
