viherkatoihin

Viherkatot, also known as green roofs, are roofs partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. They offer a variety of environmental and economic benefits.

There are two main types of viherkatot: extensive and intensive. Extensive green roofs are typically shallow, lightweight, and require minimal maintenance. They are usually planted with sedums, grasses, and other hardy, drought-tolerant plants. Intensive green roofs are deeper and can support a wider range of plants, including shrubs and trees. They are heavier and require more maintenance, similar to a traditional garden.

Viherkatot help to manage stormwater runoff by absorbing rainwater and reducing the amount of water that flows into sewer systems. They also improve air quality by filtering pollutants and producing oxygen. Furthermore, green roofs provide insulation, reducing heating and cooling costs for buildings. They can also extend the lifespan of the roof membrane by protecting it from UV radiation and extreme temperature fluctuations.

Ecologically, viherkatot create habitats for birds, insects, and other wildlife, contributing to urban biodiversity. They can also help to mitigate the urban heat island effect by lowering ambient temperatures. The implementation of viherkatot is becoming increasingly popular in urban planning and construction as a sustainable building practice.
