Green Roof Insulation Thickness

Penefol 800 1 5 is a conditionally usable membrane for small structures.

Green roof insulation thickness.

Fatrafol 808 2 3 or fatrafol 810 1 5 is the most suitable waterproof insulation for green roofs. Insulation is a key element for a successful green roof. 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. 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.

Intensive to describe green roofs that are thick enough. 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. One that we recommend considering is the green roof insulation layer. Geofoam made of expanded polystyrene eps provides an insulation layer that maintains its r value over time.

A noise reduction of 5 db was measured after the installation of a 10 cm green roof. This can add an extra level of comfort and make your property in general feel a lot better to be in. 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. Depending on the green roof layers thickness that you go with you will need to determine which are the most important to have included.

This membrane must be integrated and concealed in the structure. The thicker the substrate and vegetation the better the sound insulation.
