What do you know about the green roofing Townsville? Amid urban chaos, in some metropolises, it is practically impossible to have contact with elements of nature. Despite being a solution used since ancient times, the green roof began to become popular in recent decades, becoming a great option for those who want to have a greener environment closer to their routine.
What are the types of a green roofs?
The green roofing Townsville has three different types that vary according to the type of use, the conditions of the building, and the maintenance requirements that it demands.
- Extensive:
In this type of green roof, the project is based on a system of thin and light roofs, allowing for a planting medium measuring between 6 and 30 cm in depth. This model has a maximum thickness of 8 cm, serving as a more viable financial solution for those who want to have a more sustainable project, however, have a tighter budget.
Because it is a simpler and more practical solution to install, it is great for almost any type of building. Its weight varies between 60 to 150 kg / m² and, therefore, does not require a more robust structure to support it.
It can support the planting of some drought-tolerant plants, with shallower root systems. Thus, it is possible to grow low-growing herbs and grasses, which are the most common choices for this type of green roof.
The great differential of the intensive model is that it needs some extra care to avoid problems with rainwater overload. In addition, extensive green roofs do not require a lot of maintenance, as they do not require constant irrigation, except in very hot periods.
- Intensive:
The intensive type of green roof, on the other hand, is a more intensified solution than the previous model, requiring a more robust structure to support its weight. It can weigh between 180 and 500 kg / m² and, therefore, requires prior planning to analyze whether it is possible to install it in the building.
In addition, intensive green roofing Townsville types require care with their maintenance. Therefore, to avoid problems, you must regularly irrigate the vegetation on your roof and keep it charming for a long time.
- Semi-intensive:
Semi-intensive roofing Townsville is a mix of the two previous types. Therefore, they have a thinner planting average than the intensive model, but thicker than an extensive one. In this way, the system can vary from 120 to 250 mm, with an average weight of 120 to 200 kg/m².
