What's A Finger-Joint?
The term "finger-joint" suddenly seems to have surfaced in window covering nomenclature although it’s a woodworking technique that’s been around for years. A growing number of industry executives are describing some of their shutters as featuring finger-jointing. It’s a matter of splicing two pieces of wood into a jigsaw-puzzle type of bonded joint in order to utilize shorter pieces of wood in shutter stiles, frame, and other parts.
Those industry veterans swear that a good finger joint will hold up as well as a single piece of wood, and that the process is ecologically sound as well. But, the wood has to be matched in type and moisture content for the joint to hold up, and that process can only be used with painted finishes to conceal the joint.
