PUBLIC SERVICE ANNOUNCEMENT:
Don’t make shutters from Hardie-board!
Some large new subdivisions are being constructed right here in our area of North Jefferson County, and the builder has been outfitting the new homes with board-and-batten shutters made from Hardie (fiber-cement board).
Since I make window shutters from Cedar, I thought I might add a Hardie-board shutter to my repertoire to keep up with the competition. So, I contacted The James Hardie Co. to inquire about best building practices. My question: Which fasteners and what type of glue would work best for this board-and-batten shutter application?
The technical staff from James Hardie Co. responded with the following: “Unfortunately, we do not recommend our trim products be used to make shutters. It is not structural and there is no reliable way to attach Hardie to Hardie.”
In other words, the manufacturer has such little confidence in the material holding up over time in a shutter application, that it’s willing to walk away from millions of dollars rather than endorse their product as a shutter material.
Don’t get me wrong; Hardie is an excellent material for siding and trim but it’s not designed to connect to itself with a lap joint for shutter applications, because that connection is expected to fail over time, which means the shutters might fall apart.
Western red cedar is still a fine material for window shutters, by the way.
