Architectural membranes are flexible, lightweight materials used in building design to create structures that are both functional and aesthetically pleasing. These membranes can be made from various materials, such as PVC, PTFE, or ETFE, and are often used for roofs, facades, and canopies. They allow for unique shapes and forms, enabling architects to push the boundaries of traditional construction. These membranes are valued for their durability, weather resistance, and ability to filter natural light. They can also contribute to energy efficiency by reducing heat gain and loss. Additionally, architectural membranes are often used in temporary structures for events or exhibitions, showcasing their versatility in design.
