Abstract
A door assembly having a core positioned within a frame. The door assembly further includes a pair of opposed molded skins. There are edges adjacent the skins. The skins are made of a polymer material, a low profile additive and reinforcement fibers. Each of the skins has an exterior surface and an interior surface. The interior surface is adjacent the core. The exterior surface includes a textured pattern consisting of level portions and depressions. The depressions have a range in depth from about 0.025 mm to about 1.0 mm from the level portions. The skins further include undercuts adjacent the depressions. The undercuts have a range in extent of undercutting from about 0.025 mm to about 0.10 mm from the depressions.
