After laying out the trays with 500mm square planting areas, L-shaped brackets are installed on top of the securing brackets that hold the trays in place. There is a hole at the top of the L-shaped brackets. A wire is threaded through this hole and stretched around the perimeter. This ensures that even when the net is placed over the rooftop greening, space is maintained. The bird damage prevention net is suitable for the thin-layer tray type, fixed around the perimeter with edge materials. 【Features】 ■ A system that reduces bird arrivals ■ Bird damage prevention with space to prevent arrivals ■ Installation of wires to support the bird prevention net ■ Easy installation and low cost achieved

In 2019, a large typhoon struck Chiba Prefecture. In September of the same year, I visited several properties where we had delivered and installed work in Chiba Prefecture for a self-inspection. Self-inspections were conducted at Store A, Store B, and Store C, all of which have metal roofs. First of all, I heard that maintenance had hardly been performed, yet the condition of the rooftop greenery at each property was good. We also conducted a self-inspection to check for any issues with the installation of the thin-layer tray-type rooftop greening system. The inspection results showed no problems. Before conducting the self-inspection, I was particularly concerned about Store A, which we had delivered and installed in 2010, as the number of years since installation crossed my mind. It has been nine years since then. The plants have been growing and declining with the seasons on the rooftop, spreading their unchanging greenery towards the sky. The fixtures that secure them continue to support the planting trays without change. Our rooftop greening system is a non-irrigation system compatible with various metal roofs. [Case Overview] ■ Location: Chiba City, Chiba Prefecture ■ Delivery date for Store A: May 2010 ■ Delivery date for Store B: October 2013 ■ Delivery date for Store C: November 2014 I would like to extend my heartfelt sympathies to everyone affected by the large typhoon that hit Chiba Prefecture in 2019.

Verify thin-layer greening with numerical data. Confirm on-site, reflect it in products, and then verify again. Our company is committed to improving the quality of rooftop greening through continuous verification. We conduct multifaceted verifications, including measuring soil temperature with data loggers, cross-referencing with weather data, and recording and analyzing growth conditions. Additionally, we are accumulating insights gained through a three-year dead plant warranty. To date, we have overseen stable growth over many years among more than 2,459 construction projects. Based on this track record and verification, we have adopted a volcanic gravel mulching specification. Rooftops present harsh conditions for plant growth, including dryness, high temperatures, and high humidity. The thin-layer tray system has a shallow soil thickness, making the balance of "water and air in the soil" crucial. The specification with mulching suppresses moisture evaporation from the planting trays and rapid temperature changes, and we have confirmed through both measurement data and actual site conditions that it helps control heat retention and soil temperature increases in thin layers. As the climate changes, rooftop greening will also change. Along with the changing climate, the thin-layer rooftop greening "Mizuirazu" will evolve. We continue to apply the three-year dead plant warranty to this new specification, embodying our responsibility for quality.

This article introduces our rooftop greening system, specifically the "Mizuirazu Low Shrub Type and Flower Type (with Irrigation)" that is suitable for compliance with regulations and landscape-oriented rooftop greening.
