Sedum Roof Insulation

Sound waves are absorbed and reflected.

Sedum roof insulation.

Sedum can withstand drought for example in very hot summers. In addition to thermal insulation a green roof also has a sound insulating effect. And reduce heat loss due to wind by up to 50 compared to a bare roof. During the winter months it is possible to gain up to an extra 25 insulation in dry conditions by installing a green roof.

However there s a compromise here. Sedum is a lightweight method to create a green roof thanks to the modest substrate layer depth. It can also raise the outside temperature of the roof on average by 4 5 c when the weather is cold. Sedum has very shallow roots a key requirement for an extensive green roof considering the modest depth of the substrate layer.

To create a sedum roof contractors start by installing traditional roof framing and sheathing. These materials are covered by a waterproofing membrane which prevents moisture from entering the structure. 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.

Sedum roofs are lined with plant life rather than traditional roofing materials. Key considerations when designing green roofs include overall weight of the system to ensure it can be supported by the roof structure in addition. The substrate blocks the lower frequencies while the plants absorb the higher frequencies. 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.
