With a glass opening and a internal layer of decorative iron to add security, these doors produce an unparalleled look with unique designs inlaid in sturdy glass panes. Although most of these doors are Mediterranean style, there are also modern and contemporary options. Materials include mahogany and knotty alder for solid wood doors, wrought iron for iron grills and frames, and white laminated or tempered rain glass for glass inserts. Iron doors feature glass panels that swing open to allow for easier cleaning and security screening.
