Perlite insulation board (FSG Hydrophobic Perlite Insulation Board ) is used expanded perlite bulk material as aggregate and join waterproofing agent and binder. Then after preparing, filtering, compression molding, drying and other processes, waterproof insulation board can be produced. By using FSG Hydrophobic Perlite Insulation Board, the technical problems of insulation and water-proof in one for all types of building roof cover, can be solved effectively. So that a lot of cost for building and maintenance can be saved.  

    Product features:

    It is light, and with good thermal insulation properties. It is fireproof, dust-proof, moisture resistant, indeformable, non-modifiable, incorrodible, mildewproof, non-toxic and odorless. And it is with great hydrophobic property. The water repellency rates of it can up to 98%. The construction is safe and simple. It is available to use natural mineral as paste materials for both roof and walls.

It is mainly applied for walls and roofs of residential buildings, industrial buildings, public buildings, and swimming pool, boiler, refrigerator, some waterproofing and other special insulation projects with water-proof requirements.
