Green roof insulation properties.
Green roofs are great insulators.
So to be green you have to be cool.
In some cases a green roof may include thermal insulation typically a layer of extruded polystyrene.
The combination of substrate plants and the embedded air in the green roof system provide good sound insulation.
The basic anatomy of a green roof consists of vegetation growing medium filter membrane drainage layer waterproof root repellant layer roofing membrane support for plantings above thermal insulation vapor control layer and structural roof support.
Advice should be sought from a building energy consultant to establish the value of additional insulation considering the insulating properties of the green roof assembly substrate.
Since most of the green roof heat management happens right at the surface in the vegetation and the planting media any additional energy conservation measures that go underneath the drain layer should supplement the vegetation media heat management not the other way around.
In addition to thermal insulation a green roof also has a sound insulating effect.
Further if the roofing material doesn t have insulating properties it can create a secondary environmental issue by requiring the inhabitants of the building to crank up the climate control.
While this can be positioned below the roof deck installation above the waterproofing known as an inverted green roof is preferred as it further protects the membrane from condensation and physical damage.
So you can also save on your heating bills in the winter.
What are some of your options when it comes to roofs.
Does a green roof system have to include insulation it depends.
Especially their performance in the low frequency range could be interesting.
Quieter environment indoors and outdoors.
Sound waves are absorbed and reflected.
Due to their relatively large surface mass density low stiffness and pronounced damping properties green roofs increase the acoustic insulation on top of the basic roof.
More green roofs and fewer dark colored roofs equal a cooler city.
