Sedum roof insulation.
Sedum roofs are lined with plant life rather than traditional roofing materials.
Sedum can withstand drought for example in very hot summers.
The deeper the growing medium on your green roof the better it will insulate.
Key considerations when designing green roofs include overall weight of the system to ensure it can be supported by the roof structure in addition.
And reduce heat loss due to wind by up to 50 compared to a bare 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.
The combination of substrate plants and the embedded air in the green roof system provide good sound insulation.
However there s a compromise here.
Deep layers of substrate growing medium are extremely heavy.
A sedum green roof is not quite as good an insulator as a wildflower green roof.
It can also raise the outside temperature of the roof on average by 4 5 c when the weather is cold.
During the winter months it is possible to gain up to an extra 25 insulation in dry conditions by installing a green roof.
Sedum is a lightweight method to create a green roof thanks to the modest substrate layer depth.
To create a sedum roof contractors start by installing traditional roof framing and sheathing.
The substrate blocks the lower frequencies while the plants absorb the higher frequencies.
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.
