Sedum Roof Insulation

However there s a compromise here.

Sedum roof insulation.

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. 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. These materials are covered by a waterproofing membrane which prevents moisture from entering the structure.

And reduce heat loss due to wind by up to 50 compared to a bare roof. The deeper the growing medium on your green roof the better it will insulate. A sedum green roof is not quite as good an insulator as a wildflower green roof. Deep layers of substrate growing medium are extremely heavy.

Sedum roofs are lined with plant life rather than traditional roofing materials. To create a sedum roof contractors start by installing traditional roof framing and sheathing. 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 has very shallow roots a key requirement for an extensive green roof considering the modest depth of the substrate layer.

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. Sedum is a lightweight method to create a green roof thanks to the modest substrate layer depth. In addition to thermal insulation a green roof also has a sound insulating effect. During the winter months it is possible to gain up to an extra 25 insulation in dry conditions by installing a green roof.
