Sandwich panel :

Sandwich panel is a kind of resistant and light prefabricated walls with combined layers covered by two sheets in outer layers and different types of insulator in middle layers which is used to cover different places. Metal sheets, aluminum, plastic sheets, PVC, composite, asbestos can be used to cover two sides of sandwich panel. As insulator; different types of heat insulator, damp course and acoustic insulator including: Polyurethane foam,Polystyrene foam, stone wool. Special polymers can be used between two sheets. Except Polyurethane foam that results in high adhesivity after combing polyure and isocyanate, other insulators should be used together with special industrial adhesives that obviously cannot have quality and resistance of sandwich panel with polyurethane. These days in modern architecture sandwich panel is used to cover different prefabricated places, niches, salons, roofs, refrigerators, residential projects. Sandwich panel is manufactured in two wall and roof type with plain surface and shutter form. Sandwich panel is in different width, normally about 100cm, but length can be changed as customer’s order. Thicknessof sandwich panel is specified according to need and usage and can be manufactured in 3cm and over.
