Using soilless lawn to build a "roof garden" can directly reduce the temperature of the top floor of the house, which is warm in winter and cool in summer. The experiment shows that when the surface temperature of the top floor is 60℃ in midsummer, the temperature under the thickened soilless lawn is only 27℃. In addition, the "roof garden" can prolong the life of the roof waterproof layer and alleviate the heat island effect.

Second, improve air quality.

Lawn, like other green plants, can absorb carbon dioxide, sulfur dioxide, dust, pollutants, water and oxygen, so using soilless lawn as roof greening can purify the air and effectively improve the air quality in the community.

Third, extend the life of the roof.

The roof garden is equivalent to the insulation layer of the building, which can not only absorb ultraviolet rays, but also reduce the damage of natural disasters such as high temperature and high humidity or low temperature and cold, strong wind, rainstorm and hail, thus prolonging the service life of the roof.
