Sedum Roof Insulation
The substrate blocks the lower frequencies while the plants absorb the higher frequencies.
Sedum roof insulation. It can also raise the outside temperature of the roof on average by 4 5 c when the weather is cold. Sound waves are absorbed and reflected. To create a sedum roof contractors start by installing traditional roof framing and sheathing. In addition to thermal insulation a green roof also has a sound insulating effect.
Key considerations when designing green roofs include overall weight of the system to ensure it can be supported by the roof structure in addition. Sedum plants come in many colours and varieties so it is possible to design s edum mats blankets sedum walls or modules such as the s pod some times called the sedum tray green roof tray or modular system the s pod tailored to your needs or that of the environment. And reduce heat loss due to wind by up to 50 compared to a bare roof. Sedum can withstand drought for example in very hot summers.
However there s a compromise here. A sedum green roof is not quite as good an insulator as a wildflower green roof. Our mineral wool green roof growing mediums help to produce innovative extensive green roofs which support sedum moss herbs grasses and other vegetation where low or no maintenance is required. Sedum is a lightweight method to create a green roof thanks to the modest substrate layer depth.
Sedum has very shallow roots a key requirement for an extensive green roof considering the modest depth of the substrate layer. These materials are covered by a waterproofing membrane which prevents moisture from entering the structure. The combination of substrate plants and the embedded air in the green roof system provide good sound insulation. Deep layers of substrate growing medium are extremely heavy.
