Green Roof Insulation Value

The insulation prevents the weight of the green roof from crushing the insulation and impairing the membrane.

Green roof insulation value.

A dark heat absorbing roof surface increases demands on mechanical systems making it more difficult to adequately cool a building whereas a green roof reduces the temperature of the roof and therefore the building itself. In order to make sure we are all clear on how insulation works particularly in a green roof system we need to take a little journey through the lexicon of insulation terminology starting with. Determining insulation r value accuracy. The extra layers of a green roof also serve as insulation.

Every construction design architect engineer a e knows a material s r value is an important factor when specifying insulation products with many regulations requiring minimum values for wall ceiling and roof assemblies. Sometimes it s wet sometimes it s dry. A green roof system provides good sound insulation keeps the living space quieter and creates more pleasant surroundings in urban areas and it contributes to noise. A green roof however is in a constant state of flux.

The protective layer can be a slab of lightweight concrete insulation. Experiments and measurements in a laboratory can test the insulation value of the product. A light weight extensive green roof can include insulation below the membrane. This may not seem much but for the human ear an 10 db reduction in noise levels is 50 quieter.

What is the r value of a green roof the most common request i get from architects and engineers is for the r value of a green roof system. The roof s membrane needs protection to prevent deterioration. The degree of sound insulation will depend on the thickness of the green roof structure.
