The classification of isogams is done based on various parameters, which we will briefly examine in this field below:
*️ ️ Types of isogam based on its raw materials *1
Polymer Isogam, which consists of polyester and tissue layers in addition to bitumen, and has high durability, elasticity and thickness. Blown isogam, in which they use blown bitumen, but it does not have the quality of the polymer type. This type of isogam is not used for construction and is often used in car batteries and plating.

*️ ️ Types of isogam based on the number of layers and thicknesses *️
Isogams are also divided into 2 models, one-layer and two-layer based on the layer.
In the single-layer model, only the polyester layer is used, and in the two-layer type, they also use tissue in addition to polyester. .
*️ ️ ️ Types of isogam based on the coating *
Nowadays, it can be seen that Izogams are produced in 3 ways with aluminum coating, without aluminum coating and with pebble coating, the first example is used for the roof and things that are exposed to sunlight in the insulation.
Sample The second one is used to insulate building floors such as bathrooms, swimming pools, toilets, etc.
The third example is also usually used for facade isogham.
