In order for the water balance in built-up areas to closely resemble the balance in undeveloped areas, not only has stormwater to be retained but it must also evaporate again. This is where the HydroSpacer® HS 170 in the Zinco system build-up “Sponge City Roof” comes into play. It provides up to 160 l of storage space per square metre of roof area and subsequently supplies the stored water to the vegetation.

The cities of the future are blue and green

GaLaBau 2026, the industry meeting point, stood for networking, experience and inspiration for all. Networking was also proved to be a success factor for the renowned green roof manufacturer, Zinco, who participated this year together with Elevate. The latter is a sister organisation within the Holcim Group and the provider of premium insulation solutions, specialising locally in waterproofing for ponds and water basins.

New Chapter begins for Zinco GmbH as Ulrich Schäfer and Dieter Schenk bid farewell

Ulrich Schäfer and Dieter Schenk stepped down as Managing Directors of Zinco GmbH on 30 June 2026 as part of the generational change at the company.

The entire green roof sector is also saying goodbye to two people who have influenced the development of the market for decades.

Zinco – only manufacturer worldwide with over 20 Environmental Product Declarations (EPDs) for green roof systems

Verified Environmental Product Declarations (EPDs) for construction materials are becoming enormously important as they comprise a transparent and reliable source of information for planners and decision makers. While the provision of this data by manufacturers is still voluntary, Zinco was already a pioneer on the green roof market with its first core EPD in 2020. Including the current verifications, EPDs are now available for over 20 system build-ups.

St. Lawrence Market district, which comprises the St. Lawrence Hall and the South and North Buildings, has been a historic landmark in Toronto for over 200 years. Integrated into this heritage-rich context, the new five-storey St. Lawrence Market North commands attention with its glass atrium and the striking greened barrel roofs, covering an area of 1,500 m². This extraordinary green roof sets a new benchmark for architecture and sustainability. Installing a green roof on a 45° pitched surface pushes the boundaries of sloped green roof construction.
