What Optigruen does

Optigrün international AG, headquartered in Krauchenwies-Göggingen in the district of Sigmaringen, southern Germany, is a private, owner-managed family business and one of Europe's established system providers for green roof and building greening solutions. Founded in 1972, the company designs, manufactures, and distributes a complete portfolio of green roof system solutions — Economy, Lightweight, Nature, Retention, Pitched, Solar Green, Garden, Landscape, and Public roofs — together with the underlying component ecosystem including protection and storage fleeces, drainage boards (e.g., FKD series), drainage material, substrates, inspection chambers, outlet throttles (Smart Flow Control), vegetation and fertiliser, planters, solar mounting frames, edge elements, gravel retainers, drainage gutters, and fall protection products.

The business monetizes primarily through hardware sales of system components and engineered solutions, priced on a per-square-metre basis (from approximately €40/m² for urban gardening systems and €75/m² for landscape roof systems, net including installation) and per-watt-peak for solar mounting (€1.05-1.26/Wp for Solar vertikal; from €178/kWp for Solar TOP retrofit). Go-to-market is executed through a network of approximately 140 partner companies across Europe supplemented by direct engagement with architects, planners, contractors, and building owners; distribution also extends into the gardening and landscaping sector and the building materials trade. With approximately 160 employees and an annual production footprint of over 5 million m² of roof surface worldwide, Optigrün positions itself as the market-leading system provider for green roofs and green buildings in Europe, with active markets in Germany, Austria, the Netherlands, France, Poland, Greece, Italy, and the Czech Republic, and selected global reference projects (including Brooklyn Grange, New York).

Products and services

• Economy roof Entry-level green roof system solution designed for cost-effective roof greening with basic components for waterproofing protection and vegetation support, targeted at projects requiring economical green roof installations.
• Lightweight roof Green roof system designed for structures with limited load-bearing capacity, using lightweight materials while maintaining effective drainage and vegetation support for retrofit applications.
• Nature Roof Extensive green roof system supporting natural vegetation with minimal maintenance requirements, suitable for roofs with shallow substrate depths.
• Retention roof Green roof system with intelligent Smart Flow Control outlet throttle that delays stormwater discharge, contributing to sponge city rainwater management with discharge coefficients as low as Cs = 0.1-0.2.
• Pitched roof Green roof system designed for sloped roof applications with enhanced erosion control and secure vegetation establishment on pitched surfaces.
• Solar green roof Combined photovoltaic and green roof system where solar mounts are supported by the green roof structure without roof penetration, increasing PV efficiency through evaporative cooling from vegetation.
• Garden roof Intensive green roof system supporting diverse plantings including lawns, shrubs, ponds, and urban gardening with terraces and kitchen gardens.
• Landscape roof High, multi-layered intensive green roof enabling varied planting with shrubs and trees, visually indistinguishable from ground-level green spaces, with costs from 75 €/m² for 1,000 m². Water retention rates of 80-95%/year.
• Public roof Traffic roof system for walkable and drivable surfaces including passenger cars and lorries, with subcategories for walkable areas, greenable pavements, and retention functions.
• Solar vertikal mounting system Vertical solar mounting system for combining with existing green roofs, featuring bifacial/TOPCon/Double Glass modules (160 Wp nominal, 14 kg), priced from 1.05-1.26 €/Wp.
• Solar TOP Retrofit system Specially developed system for retrofitting photovoltaic modules on extensively greened flat roofs without roof penetration, with target price of 178 €/kWp or 89 €/module from 500 modules, fully removable for temporary use.
• Urban Gardening system Special form of intensive roof greening for growing fruits, vegetables, and culinary herbs with substrate depth of 80-400mm, costs from 40 €/m², water retention rates of 50-80%/year.
• Protection and Storage Fleeces Range of protective fleeces including RMS (Protection and Storage Fleece), FIL (Filter Fleece), SGL (Protection, Separation and Slip Layer), SSV (Structured Storage Fleece), RSV, TGF (Separation and Slip Layer), TWB (Root Protection Membrane) products.
• Drainage Boards (FKD series) Drainage and water storage elements including FKD series boards (FKD 40, FKD 60BO, FKD 60BU) that provide drainage capacity and water retention for various roof types.
• Substrates Growing media including Intensive Substrate I, Lawn Substrate R, Aeration Substrate U, and Intensive Substrate Urban Soil US for various planting applications on green roofs.
• Smart Flow Control (SFC) outlet throttle Intelligent flow control device for retention roofs that enables controlled discharge of retained rainwater, contributing to sponge city and intelligent rainwater management solutions.
• Solar mounting frames Mounting systems for photovoltaic modules on green roofs including SOLAR TOP retrofit system and Solar vertikal vertical mounting system.
