PU stone, or Polyurethane stone, is a lightweight, durable, and versatile decorative material made from polyurethane. It is designed to mimic the appearance of natural stone but is much easier to handle, cut, and install. PU stone panels are often used for interior and exterior wall cladding, offering a realistic stone texture and aesthetic while being resistant to moisture, mold, and termites. They are popular for their affordability, ease of maintenance, and ability to enhance the beauty of spaces without the weight and cost of real stone.
