Green Roof Insulation Thickness

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 roof insulation thickness.

Insulation is a key element for a successful 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. Fatrafol 808 2 3 or fatrafol 810 1 5 is the most suitable waterproof insulation for green roofs. In 2004 dunnett kingsbury conducted research at the airport in frankfurt germany.

This is most noticeable in intensive green roofs since there is a thicker and more consistent layer of soil which provides a higher insulating value. 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. One that we recommend considering is the green roof insulation layer. The lithoplast dren 20 1 0 studded membrane is then placed on the surface.

Depending on the green roof layers thickness that you go with you will need to determine which are the most important to have included. 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 thicker the substrate and vegetation the better the sound insulation. A noise reduction of 5 db was measured after the installation of a 10 cm green roof.
