Green Roof Insulation Thickness

In 2004 dunnett kingsbury conducted research at the airport in frankfurt germany.

Green roof insulation thickness.

Fatrafol 808 2 3 or fatrafol 810 1 5 is the most suitable waterproof insulation for green roofs. Depending on the green roof layers thickness that you go with you will need to determine which are the most important to have included. Insulation is a key element for a successful green roof. A noise reduction of 5 db was measured after the installation of a 10 cm green roof.

It is common practice to use the term extensive to describe green roofs that are very thin and will only support hardy drought resistant vegetation such as sedums herbs and perennials. The lithoplast dren 20 1 0 studded membrane is then placed on the surface. Penefol 800 1 5 is a conditionally usable membrane for small structures. This membrane must be integrated and concealed in the structure.

Geofoam made of expanded polystyrene eps provides an insulation layer that maintains its r value over time. The nominal thickness of a green roof is the approximate total height of the soil and drainage components that constitute the green roof system excluding the roof structure insulation waterproofing and plants. The thicker the substrate and vegetation the better the sound insulation. Intensive to describe green roofs that are thick enough.

Available in various densities r values and sizes it is the perfect solution for installation under the plants and growing medium of a green roof. Green roofs can help reduce energy costs for a building by acting as another layer of insulation between the inside and outside of the roof.
