Thermal insulation stone wool board is a kind of mineral wool. It is fluffy short fibers made from natural Stones. It belongs to the Grade A non-combustible external wall insulation material. Here we will introduce how we do a good job of pasting the stone wool fireproof isolation belt.

     When we carry out the pasting of the external wall thermal insulation stone wool board, we must do a good job in the pasting of the Grad A non combustible fire isolation belt.
     The pasting of the thermal insulation stone wool board fire isolation belt should be carried out in a unified process with the large wall thermal insulation board, that is, the external wall thermal insulation board should be pasted from bottom to top. When the pasting of board reaches a certain height, start pasting the insulation stone wool board fire isolation belt from the external corner of the wall. When the stone wool is pasted, it is pasted in the direction perpendicular to the stone wool fiber. Because the stone wool used in the fire isolation belt is made by the pendulum method, the tensile strength parallel to the fiber direction is low, which is 10kpa, but the tensile strength perpendicular to the fiber resistance is very high, which is greater than 150kpa, which is higher than that of EPS insulation board. So pasting stone wool in direction perpendicular to the  the stone wool fiber, can fully meet the tensile requirements of the thermal insulation system.
