VRE Systems manufactures an easy-to-assemble round structure for seasonal garden center sales. The vinyl roof fabric has fire retardant properties and can be equipped with strips of frosted panels to allow entry of natural light. The gable ends are independent panels with built-in ventilation screening. Walls are optional and can incorporate partial sliding door openings on all sides. Walls can be covered with a combination of solid color vinyl borders with clear vinyl for good visibility. Standard sizes are in multiples of 20 feet.
