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 roof insulation.
Deep layers of substrate growing medium are extremely heavy.
The substrate blocks the lower frequencies while the plants absorb the higher frequencies.
Sedum has very shallow roots a key requirement for an extensive green roof considering the modest depth of the substrate layer.
Sound waves are absorbed and reflected.
These materials are covered by a waterproofing membrane which prevents moisture from entering the structure.
To create a sedum roof contractors start by installing traditional roof framing and sheathing.
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.
The combination of substrate plants and the embedded air in the green roof system provide good sound insulation.
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 can withstand drought for example in very hot summers.
Sedum roofs are lined with plant life rather than traditional roofing materials.
It can also raise the outside temperature of the roof on average by 4 5 c when the weather is cold.
And reduce heat loss due to wind by up to 50 compared to a bare roof.
Sedum is a lightweight method to create a green roof thanks to the modest substrate layer depth.
However there s a compromise here.
