To achieve healthy construction designs it is important to make a proper selection of green roof construction materials.
Green roof structure thickness.
A green roof with a lightweight solution of 30 kg m2 is only possible with sedum vegetation and a green roof with a weight of 220 kg m2 is composed of a combination of sedum grasses herbs or host plants.
Roughly speaking extensive green roofs have a thickness of between 4 and 15 cm and a weight of between 30 and 220 kg m2.
Beam design procedure 1.
A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane it may also include additional layers such as a root barrier and drainage and irrigation systems.
One important item to design for is an increased structural load.
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.
Because water runs off the roof more quickly a thicker substrate layer is needed.
Also the green roof drainage layer material is made to be sturdy and strong so that piercing can be limited and that the integrity of the entire program can be retained with ease.
Green roof structural design description to accommodate the increased load on the roof structure the existing structural system.
The green roof drainage layer thickness makes sure that nothing can go wrong below offering a solid and effective guard.
Calculate live and dead loads being induced on the slab.
Intensive to describe green roofs that are thick enough.
The slab thickness for a typical bay was calculated to be 6 5.
This is especially true of intensive green roofs which can have soil that is two feet deep or more.
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.
With green roofing one can observe a great improvement in health and well being.
There are a number of things to consider when designing for a green roof.
Shallow pitched green roof 5 25 the structure of a shallow pitched green roof differs slightly from the structure of a flat roof.
Steeply pitched green roof 25 40 sempergreen has the perfect solution for pitched roofs.
These materials will determine the efficiency of the roof and keep your house free from trouble.
