Oxygen production
Green roofs contribute to an improved air quality, especially in urban environments where the quality of the air is often unsatisfactory. The vegetation on the rooftop produces oxygen on the one hand and absorbs polluted particles from the air on the other hand.

Improved sound-proofing
A RENOLIT ALKORGREEN roof system serves as an excellent sound insulator. Green roofs can be very efficient in reducing indoor noise attenuation from hail and rainfall etc…

Benefiting the urban environment
Green roofs create more natural green areas in the urban environment. The plants on the roof give the owners a more natural view, instead of the increasingly dominating black or grey flat roof surfaces.

Reduction of heating/cooling costs
A green roof provides extra insulation and energy efficiency for the building. Because of its insulating properties, Alkorgreen roofs have a large impact on the interior temperatures, reducing the amount of energy needed to heat a building in winter and to cool the building in summer. As a result, RENOLIT ALKORGREEN SYSTEM ROOFS operate more efficiently than the traditionally roofed buildings, resulting in lower energy costs for the building owner.

New environment for the fauna and flora
A living roof brings nature into the cities and industrial areas. It offers a high biodiversity that may prevent some animals from disappearing from the urban environment. Apart from this, green roofs may offer high-rise flat residents a functional space or entertaining area, replacing the traditional garden.
