Inside the home, interior doors affect the look and feel of a room while providing privacy and deadening sound.Exterior DoorsExterior doors need to be heavier and more durable than interior doors, as the door must be able to withstand the rigors of rain, snow, heat and cold. Exterior doors are also a defense against criminal entry and block noise from the street.Exterior doors may fulfill very practical functions, but that doesn't mean they need to look utilitarian. Entry doors can include glass paneling, grilles and decorative carving, all of which add to your home's beauty.Interior DoorsInterior doors offer more design choices than exterior doors, because the doors don't have to withstand the same forces. Interior doors are often hollow frames covered with a plywood veneer, but can also be made of solid wood if you want a classical look that also deadens sound.Glass DoorsGlass doors blur the line between doors and windows.
