A stile and rail door is built with a rigid frame and floating panel. This allows the door to maintain a consistent width and flatness even if the wood moves due to season and environment changes. The entire door can be built from recycled content and all with NAUF glues. All of these doors are fully covered by our warranty. Unlimited options abound for panel design, applied moldings and profiles. The flush plank doors can give a different look or feel to a project. They basically look like boards edge glued together in one flat consistent plane. There is less decoration, and it is a simpler design. Our flush plank doors can be built with a foam core over the majority of the surface area which allows us to build a lighter or better insulated door. These doors never have recycled content in their core. Typically the most that they will be reclaimed material is about 33% content overall, but everything that shows on the face or edges is matching reclaimed material. The core is usually a combination of engineered materials. Be sure to ask the source, some of these materials we cannot get as a NAUF product. Our warranty excludes coverage on warping in this style of door as is the industry standard. Generally these doors cost slightly less than a comparably sized stile and rail door. If we do not use a foam core product, these doors tend to be heavier than normal. Since there is no panel or rail system, one has more flexibility to apply strap hinges or other decoration anywhere on the surface of the door.
