Planted modules on a self-adhered membrane, cover board and insulation.
Layers, in order
| # | Layer | Thickness | Spacing |
|---|---|---|---|
| 1 | LiveRoof modules with plants and engineered soil | 4 1/4 in | at 16 in o.c. |
| 2 | Sarnafil G476 self-adhered waterproofing membrane | 1/16 in | |
| 3 | Sarnafelt NWP (if specified) | 1/8 in | |
| 4 | Grounding screen for electronic leak detection | 1/16 in | |
| 5 | DensDeck Prime cover board | 1/4 in | |
| 6 | Sarnatherm polyiso, 2 in R-10 | 2 in | |
| 7 | Thermal barrier | 1/2 in |
Build steps
- Waterproof under the green roof (Roofer). Thermal barrier and polyiso over the slab, DensDeck Prime cover board, the grounding screen for leak detection, Sarnafelt if specified, then the self-adhered Sarnafil G476 membrane.
- Set the green roof modules (Roofer / landscaper). Lay the Sarnafil drainage composite (gray fabric up) over the waterproofing membrane, then set the pre-grown LiveRoof modules in rows tight against each other, with a vegetation-free gravel edge.
