Green Roofs are Growing

The core of a successful green roof is the growing media that makes it grow. A successful green roof is engineered to be lightweight, porous and support plant life. Growstone is the basis of a successful green roof.

Since green roofs last longer than conventional roofs, reduce energy costs with natural insulation, create peaceful retreats for people and birds, and absorb storm water, using long-lasting Growstones as the key ingredient in a green roof growing media will allow you to achieve your objectives.

A proper green roof growing media possesses the following properties:

· Good drainage and aeration

· Good water holding capacity

· Good nutrient holding capacity

· Permanent, lightweight but sturdy, and stable media

Green roof growing media formulas are designed with each specific project in mind. And for that reason, no matter if your project is in the Pacific Northwest, the Northeast, or in a warmer climate, Growstone is the answer to these changing climate needs. Growstones perform well in all situations.

Growstones’ water holding capacity keeps moisture deep in the media, encouraging the plant roots to grow deep so they are more drought tolerant. Growstones’ main mission is to provide aeration to the growing media, but its porous nature allows plants to quickly “knit” into it.

With its lightweight of 11.5 pounds per cubic foot, Growstones open up a whole new class of roofs that previously were not candidates for one. The thinner the green roof soil layer, the higher the physical demands on the plants. Using Growstones as the basis for a green roof growing media allows shallow soil depths without risking root damage from heat and frost fluctuations.

Green roofs are divided into two categories – extensive and intensive. Extensive green goofs, the more common of the two categories, use a shallow growing medium of five inches or less. Growstones can be used successfully in this shallow medium to reduce weight and provide growing conditions for plants to thrive in that normally would not have in a shallow soil. Intensive green roofs use hardier plants that require a growing medium of at least 6-12 inches. Roofs in this category are heavy presenting structural challenges. Using Growstone as the basis for the growing media significantly reduces the weight of the soil and the structural challenges that go along with it.
