Rock wool products_Inner Mongolia Shenzhou thermal insulation building material Co., Ltd.

Rock wool, the application of the construction industry, building external wall thermal insulation partition wall and roof enclosure insulation sound-absorbing noise reduction; Petrochemical industry, petroleum, electric power, chemical industry equipment insulation Sound-absorbing noise reduction; Industrial and mining industry - industrial kiln drying oven, large diameter storage tank and ship insulation fire prevention, etc.;

Rock wool board cotton silk order different from the traditional flat wire rock wool board Thus has more pulling force and pulling force, solved the phenomenon of rock wool layer, weather resistance and drawing strength experiments show that can be at ease in the exterior wall, roof, roof, partition wall equipment insulation heat preservation and heat insulation and construction, and other fields.

Rock wool board in different work environment requirements prevent condensation of moisture, and other functions This would require the stickup on insulation outer protective layer, the shenzhou with a variety of aluminum foil cover to choose from.

Packing: according to the thickness of the customer needs to decide on the number of pieces in each package normal packing thickness of about 300-300 - mm, in order to meet the demands of logistics distribution, the shenzhou rock wool adopting thermal contraction and the two kinds of packing method, we at the request of customers, all over the world to accept OEM production of various brands, for packaging.
