How are Shuttermart shutters constructed?
Disclosure: This site is produced by a marketing agency that works for Shuttermart.
Shuttermart publishes several construction details: hand-picked poplar and Baltic birch cores, rails and stiles joined with three two-inch hardwood dowels, patented TwistLock tilt-rod hooks in place of staples, air-core louvers to prevent warping, and aluminum reinforcement for very wide panels.[1]
What is triple-dowel joinery?
Shuttermart says the rails and stiles are joined with three two-inch hardwood dowels, joinery it says is found in high-quality furniture and keeps panels from coming apart.[1]
What is the TwistLock tilt rod?
Most shutters attach the tilt rod to the louvers with staples. Shuttermart says it uses a patented hook that twists and locks into each louver, and that these TwistLock T-hooks will never pull out.[1] Its Polyclad page also lists a hidden rear tilt.[2]
Why air-core louvers?
Shuttermart says louvers with an air core insulate better and avoid the warping that solid louvers suffer from weight, humidity and hot sun. With aluminum reinforcement on large windows, it says it can make very wide single panels that will not warp, which it guarantees.[1]
What other details are listed?
- A rabbeted interlocking technique for extra light blocking on basswood shutters.[3]
- A beaded groove at the stiles and rails on wood shutters.[1]
- Hand-picked woods with no MDF, sawdust or composite fillers in the panels.[1]
