Extensive green roof project with elaborate planting areas consisting of circles with a sedum tiles as the background and contrasting planted areas with grasses and perennials. Approximately 1500 linear feet of Oly-Ola Edgings’ 4” high flexible Teco-Edg TM green roof edging was used to separate the planting areas and neatly define the project’s green roof designs. Made of 100% recycled PVC, installing Teco-Edg helps contribute to LEED ratings. Available in flexible or rigid styles, there is no need for cutting or snipping to make curves. With two height sizes available, a 6" high version designed to accommodate intensive green roofs and a 4" high version ideal for extensive green roofs, Teco-Edg comes standard with 1.5" drainage slots on its vertical base.
