Designed Green Roofs

(Semi-Intensive)

Engineered for Impact, Designed to Inspire

Achieve stormwater control, energy savings, and architectural elegance in one system.

Designed vegetative green roofs—also known as semi-intensive systems—strike the perfect balance between engineering performance and visual appeal. These systems are ideal for visible roof areas where stormwater management, energy efficiency, and architectural beauty are equally important. With deeper soil profiles and diverse plantings, they transform rooftops into functional, living landscapes.

Design Elements

  • Supports GreenGrid® 4 inch, 6 inch, and 8 inch module depths.
  • Accommodates a wide range of plant types: succulents, perennials, and native grasses.

Semi-Intensive Product Details
Intermediate Depth Modules – 6 in
Module Size 2 ft x 2 ft x 6 in
Weight Approximately 39 to 44 lb/sf fully vegetative at maximum water holding capacity.
Uses Intended for designed vegetative green roof applications or functional vegetative green roofs applications where loading is required to combat against wind loads. Excellent tool for managing stormwater and integrating into well into new or existing buildings where there is ample structural support.
Plants Succulent ground covers, conventional perennials, native forbs and grasses. When irrigated, this pallet of plant material increases.

Semi-intensive roofs are often used as building amenities accessible to the occupants as an area to enjoy nature.
