External doors play an important role in modern homes, both as a practical security feature and a way to add style and personality. However, there are also a number of other considerations to make when choosing external doors, such as the level of privacy provided and the ease of access allowed. Advances in manufacturing techniques and materials have given birth to a number of new door innovations over the last few decades, such as plate glass doors, folding door, and rotating doors.

However, most of the doors in use around the world have a long history, with most people choosing to use traditional doors in most situations. External doors can be installed in a number of locations, including the front entrance, back entrance, and side entrance of a home. Many people also use external doors to provide access and continuity between one part of a home and another.

There are some innovations in terms of door design and manufacture that have led to new trends, with modern glass doors perhaps being the most obvious example. The tough plate glass that is required for modern sliding doors was only made available in the later half of the 20th century, so these types of doors are a very modern design indeed. However, even glass sliding doors are based on traditional sliding doors that have been used for a long time. Some of the other trends in exterior door design are related to aesthetics, with many new styles and looks being appropriated over the last few decades. Advances in materials and interior design principles have accelerated these trends, with many people choosing doors that complement the designs and style of the rest of their home.

While single vertically hinged doors are by far the most common variation, double hinged doors are also common in larger homes and more ornate settings. Hinged doors are also common on the sides and backs of houses, although sliding doors are also used in these situations. Some modern applications also use flush doors and moulded doors, which are completely smooth doors which use plywood or MDF over a light timber frame. Exterior doors play an important role in security and aesthetics, and choosing the right doors for your home can make a real difference to the overall appearance.
