Perlite is a kind of volcanic glass which was made by lava created in the acid phase of the magma. This lava cools and broken into pieces that can be seen by eyes or via microscope. Perlite has water drops within its body. The word “perlite” is derived from the word “perle” or “pearl” because some perlite types are turned to small balls as bright as pearl when they are broken. It is a naturally and volcanically comprised type of acidic glass that can expand with temperature and turn into a porous form in the commercial usage. Perlite dilates 4-20 times approximately when it is heated in 900-11000C in certain size of particle, then it pops like corn and its density becomes very light.

It has 2-6% bound water within its body and it is a glassy rock. When it is heated between 800 and 11500C and it gets bigger as 4-20 times, a low-density material called EXPANDED PERLITE is acquired. Expanded perlite is used in construction, filtering, isolating, textile washing, filling materials, casting, petrol industries, agriculture, preventing marine pollution and cleaning. Applying as double glass in the walls, roofs and floor and improving the boiler rooms can ensure 70% saving from the warming expenses.

As a consequence of this application;

- As a consequence of this application;

- Isolation is made against undesirable noises in buildings.

- The life of the building is extended because isolation which is suitable for the building physics prevents temperature differences on the material which changes in a short time.
