Simpson Door Co. has expanded use of its “Water- Barrier” technology to contemporary, flush doors made from any kind of wood and featuring different shapes, designs, and windows with standard raised or flush Shaker moldings. The water barrier combines a moisture-resistant overlay with a thermoset acrylic latex topcoat on the door’s exterior. The moisture-resistant surface can then be painted any color for a contemporary finish. Pricing varies. simpsondoor.com
