What about extreme heat?
Heat can warp poly, vinyl, or basswood shutters, but not our engineered poplar. Our vendor, O’Hair Shutters, is a mill in Lubbock, Texas that is over 75 years old. In their extreme climate, they start the drying process by “baking” the lumber in the Texas sun. But the most important thing O’Hair Shutters has been doing for over twenty years is “joining” their wood with radio-frequency gluing equipment. This creates strength in every component and keeps the materials from warping (even the louvers are made from joined wood). All the strengths of these components add up to the ability to build a 50” wide panel and warrant it for life. We know of no other wood shutter that is built like this.
Unlike our shutters, basswood and composite shutters are susceptible to warping, but this is not entirely from the sun. And with poly and vinyl shutters, the softening of plastic in the heat makes warping very likely. Plastic and the sun don't mix!
If you still don’t believe engineered solid wood is the best material for shutters, get online and search for shutter companies in the cities with desert climates such as Tucson, Phoenix, El Paso, San Antonio, Palm Desert or Las Vegas. Call the shutter companies in these markets and ask them what type of material they use to build their shutters. They all use wood for good reason!
