GROWVista 2X – Extensive, Semi-Intensive & Intensive Green Roof Applications

Semi-Intensive Vegetated Green Roof Module

GROWVista 2X

The GROWVista 2X Vegetated Green Roof Module is a versatile modular green roofing system ideal for extensive, semi-intensive, and intensive green roof designs. This system takes the features of the GROWVista 2 module and adds our NutrawallTM Depth Extenders to expand the design flexibility to include semi-intensive and intensive green roof options. The extender walls are perforated to allow moisture, nutrients and plant roots to move and grow from one module to the next. This is helpful in keeping a vegetated green roof strong and healthy.

Extensive Green Roofs

 

Extensive green roofs are designed to be drought tolerant and require minimal maintenance. Growth media for extensive green roofs is comprised mostly of light-weight aggregates and minimal organic material. Plants that work best for extensive style green roofs include mainly varieties of Sedum and other succulents, plus some mosses, herbs, and grasses. Plant selections should be determined based on regional climate and site specific conditions.

Semi-Intensive Green Roofs

Semi-Intensive designs fall in between extensive and intensive designs. They generally incorporate a heavier growing media with more organic material than extensive media blends. These green roofs may require more maintenance and permanent irrigation depending on plant selection and climate. It is best to still use drought resistant plant species based on regional climate and site specific conditions. Plants for semi-intensive designs can include succulents, ornamental grasses, herbaceous perennials, and small shrubs. Some examples of these designs are perennial flower gardens, wildflower meadows, or rolling prairies. These designs can be accomplished using the GROWVista 2X-6 or 2X-8 modules.

Intensive Green Roofs

Intensive green roofs are often referred to as rooftop gardens. They typically are used for high-end design, incorporating ornamental plants and trees and hardscape elements. These designs will require regular maintenance and permanent irrigation. They require a heavier growing media with a more organic make up than extensive or semi-intensive media blends. Plants for intensive green roofs can include succulents, ornamental grasses, herbaceous perennials, shrubs, and small trees. Intensive green roofs can also be used to create beds to produce herbs and vegetables. These designs can be accomplished using the GROWVista 2X-8 module.
