And this is our guide to everything you should know about the insulating effects of green roofing.
What is the insulating effect of green roofing?
Green roofing offers two different types of insulating effects, including:
- Thermal insulation
- Sound insulation
Green roofing and thermal insulation
Green roofing has a heat regulating effect in both the summer and winter months. During the summer months, buildings can heat up significantly because of the sun. Installing a green roof allows the sunlight to be reflected instead of absorbed, which helps to maintain a lower temperature in the building. At the same time, moisture in the vegetation will evaporate, contributing to an overall cooling effect.
In the winter, the substrate layer is thicker than standard insulation and this will prevent the warm air inside the building from escaping.
Green roofing and sound insulation
Its not only thermal insulation that a green roof can provide. In fact, a green roof can also provide effective sound insulation too. This is because the plants and the substrate both absorb and block the sound frequencies, which prevents them from entering your building. The degree of sound insulation will depend on the thickness of the green roof structure, and the combination of vegetation and substrate. Studies have shown that green roofs reduce sound resonance by 3 dB and provide sound insulation of up to 8 dB. In real terms this reduces the sound by up to 50%.
