Attenu8® System - Roofing System
Verified by manufacturer 1 day ago
Roofing system.
Application
Suitable for:
- Intensive green roofs: Creates a finish for lawns and intensive specialist planting.
- Semi-intensive green roofs.
- Extensive green roofs and bio-diverse roofs: Designed to be self-sufficient and low maintenance, creating a natural habitat supporting birds, insects and invertebrates.
- Biosolar roofs.
- Blue roofs: Reduces and controls the peak rate of storm water discharge, and is engineered to attenuate water at roof level to alleviate the risk of flood at ground level.
