Green roofs, written as a system
Keep green roofs written as a system. A gardened roof is a roof, a root barrier and a drainage build-up. Catalogue 2026 names the membrane that carries ETA 11/062. Therefore the planting is not a Krypton membrane.
Why green roofs written as a system need a named membrane
Impermax Polyurea H (hot-spray hybrid polyurea) is the hot-spray hybrid written for roofs and green roofs, with ETA 11/062. It is also marked for root penetration in Catalogue 2026. Impermax B 1K (one-component polyurethane-bitumen) is the bitumen-PU the catalogue calls root-resistant for details and foundations. Impermax 2K is listed for green roofs among its uses.
Do not print a separate Root mark beyond the allowed Catalogue 2026 set. The application page for gardened roofs is the specifier path: primer, membrane, finish, then documents. The planting build-up is not given a kilogram rate here.
However, if the roof is only a roof, use the pedestrian or industrial roof application. Do not use the garden card. Also, read consumption from the current TDS, then the calculator.
What stays off this note
This note will not invent a drainage mass. Green roofs written as a system still send the reader to the current sheet.
See gardened roofs, Impermax Polyurea H, and documents.
Outbound reference: EOTA.
A planting build-up does not carry ETA 11/062. Only the named membrane does.
Therefore the current TDS remains the source for mix ratio, overcoat and consumption. Then the calculator sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. After that, open documents. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
