- System Summary
- Carlisle Extensive Roof Garden System, also known as a "shallow" green roof, is a built-in-place system with a media depth ranging from 7 cm (2.75 in) to 12.7 cm (5 in). Extensive green roofs are the most commonly specified type due to their lightweight design and cost-effectiveness, making them ideal for retrofit applications. The shallower growing media depth is well-suited for low-growing, drought-tolerant vegetation like sedum, which requires minimal maintenance compared to other green roof types.
