Stormwater Characteristics of Greenroof Trays and Bags: An analysis of stormwater runoff characteristics in Greenroofs

Product Information

The biggest factor that influences how well green roofs work is the volume of moisture in the soil. It is important to keep the soil from becoming very dry or near the plant “wilting” point. So, it’s important to monitor how much water the plants are using and irrigate appropriately. But, adding too much water doesn’t help the cooling – and it’s wasteful of the water. We believe it may be the largest green roof in Ontario and the City of Toronto has told us it’s the largest in the city,” says Jason MacDonald, a project manager with the construction department of the Toronto Transit Commission (TTC), which owns the facility. This is very dependent on your unique requirements. Any commercial green roof should definitely have an irrigation system. For residential projects, a green roof should be watered if we go without rain for two weeks or more. Whether this is done with a system or yourself is up to you. The important factor is that it happens. What other materials will I need to buy along with my M-Trays®?

While some green roofs are elaborate undertakings consisting of soil and large plants, the TTC opted for the sedum tray system for reasons that include ease of installation, low maintenance requirements, and, if needed, speedy removal and replacement.

The designation depends on their depth, type of vegetative cover, and function. Green Roofs also purify the air, help to regulate indoor temperatures, offers natural sound insulation (11 decibels), with flora that encourages insect biodiversity. Green roofs can provide a calm green space in which to live and provide a feeling of well-being when visible.

One great thing about these rooftop planter trays is their complete green roof system. It has details ranging from growth media and drainage to rain retention and filtration. Mount the tray directly atop your roof’s waterproofing system for the best result. This will work as a protection against heat fluctuation and solar radiation. Intensive green roofs offer more cooling and energy savings benefits than do extensive green roofs. The increased soil depth and plant density of intensive green roofs prevents heat from moving down to ceiling height. Energy use can be reduced 10 to 30 percent when a building has a green roof. This effect is more significant in hot, dry climates than in humid or temperate climates. For example, intensive green roofs reduced indoor heat by 2.5°F (1.4°C) in the hot, dry urban area around Cairo, Egypt. The same type of roof only reduced indoor heat by 1.4°F (0.8°C) and 1°F (0.6°C) in the humid climate of Hong Kong or the temperate climate of Paris, respectively.

However, you can make that possible with a rooftop garden because the plants on your green roof constantly filter the air from particulates. Then you’ll need to consider what type of sedum plants you’d like to use. Whilst the majority of very good value, pre-grown sedum kits can cost several thousands of pounds for a larger project. Whereas small sedum DIY projects can be created for a few hundred pounds. All you need is: Modular roof trays are the best option for creating a roof garden.
