rooflite® is a product line of certified growing media designed specifically for green roof application. Precisely engineered and manufactured, they comply with all related ASTM standards as well as the German FLL1 - Greenroof Guidelines. The history of modern green roof technology began over thirty years ago in Germany. The German FFL - Greenroof Guidelines reflect the latest developments and worldwide acknowledged state-of-the-art technology. The FLL-Green Roof Guidelines define exact requirements and testing procedures for all green roof components.

Requirements for growing media are related to:

• Environmental Compatibility
• Salt Content
• Plant Compatibility
• Organic Matter Content
• Particle Size Distribution (Gradation)
• Nutrient Content
• Maximum Water Holding Capacity
• Limitations of Contamination
• Air-Filled Porosity at Max Water
  Holding Capacity
• Fire Resistance
• Water Permeability (Saturated
  Hydraulic Conductivity)
• Frost Resistance
• pH Value
• Structural Stability

By meeting these guidelines, rooflite® green roof growing media will function properly as a component of a corresponding green roof system irrespective of where it is located. Adjustments must be made to the green roof system, and most importantly the plant selection, for the local environments and conditions.

All rooflite® products are manufactured with strict quality control and include regionally available components like HydRocks® and USCC STA approved  premium compost . Look for the green ec2c granules as your assurance of genuine rooflite® quality.
