Outer wall stone wool board is also known as Insulation stone wool of Exterior Walls. The main raw material is natural basalt, and the high-speed centrifugal equipment is used to make the inorganic fiber, then the special high-strength adhesive and dust-proof oil are added in, and finally the temperature is solidified.

Features: high compressive and tensile strength, low water absorption and hygroscopicity, no thermal expansion and contraction, aging resistance, very good stability, fire resistance and heat insulation performance are first-class.

Application: mainly used in the sound insulation and heat preservation of building walls and roofs, fire prevention and noise reduction of firewalls, fire doors and elevator shafts.

As the natural basalt is selected as the main raw material for the outer wall stone wool board, the production cost is much higher than the ordinary mineral wool stone wool board. 90% of the common outer wall stone wool board on the market is mineral wool, or the basalt content is 30%, 60%, 80%. The price of Xuanwu cotton with 100% content is the highest, so-called one cent for one cent.
