Introduction to fireproof sandwich panel in Iran

What is fireproof sandwich panel?

In this period, one of the most important and widely used construction principles is the use of fire-resistant materials, which is a very important issue. Considering that it includes all buildings, but buildings such as hospitals, industrial sheds and factories and warehouses are of special importance.

The construction of completely fireproof structures is a bit expensive, but it is possible to use these materials with high fire resistance and reduce costs. In fact, the word “refractory” does not mean that it is fireproof, but it postpones the time of burning and destruction, and the destruction takes place in a later period of time.

The topic that is considered here is the construction of structures with high resistance against fire and reducing costs.

The sandwich panels that are produced according to these cases are called fireproof sandwich panels.

The fireproof sandwich panel is one of the types of sandwich panels, which consists of three layers, and in the middle core part, rock wool foam is embedded, rock wool is a natural mineral fiber, which is like white cotton material.
