This is a set of 8' double doors made out of solid Mahogany, one piece style and rail wood (not a veneer, laminated, or engineered). We only make USA doors. The stain and seal is eight coats of poly with UV inhibitors on each side and sanded between each coat. All doors, jambs, and moldings are … done the same way. Our entryways usually get about 14 years before they need to be refinished. We've been making these for 30 years, so we have a pretty good track record. The stained glass panels are incased inside of an insulated unit with tempered glass on both sides for security and protection. The stained glass panel is made with beveled glass and stained glass that has been etched, painted, and fired to get this particular look. This entryway has an adjustable threshold, kerfed weatherstripping, and ball bearing hinges.
