Hotel Burj Al Arab - Features and Exterior

ExteriorThe Burj Al Arab artificial islandThe building design features a steel exoskeleton wrapped around a reinforced concrete tower. Notably the building is shaped like the sail of a dhow, with two "wings" spread in a V to form a vast "mast". The space between the wings is enclosed by a Teflon-coated fibreglass sail, curving across the front of the building and creating an atrium inside. The sail is made of a material called Dyneon, spanning over 161,000 square feet (15,000 m²), consists of two layers, and is divided into twelve panels and installed vertically. The fabric is coated with DuPont Teflon to protect it from harsh desert heat, wind, and dirt; as a result, "the fabricators estimate that it will hold up for up to 50 years."During the day, the white fabric allows a soft, milky light inside the hotel, whereas a clear glass front would produce blinding amounts of glare and a constantly increasing temperature. At night, both inside and outside, the fabric is lit by color-changi
