The rock wool outer wall thermal insulation board is designed and manufactured specifically for the external thermal insulation and thin plastering system of the building. It is suitable for the thermal insulation or energy saving of the external walls of newly built or existing buildings where the foundation strength is a dense structure such as concrete or brick walls. Transformation. Natural minerals such as basalt, gabbro, dolomite, iron ore, and bauxite are used as the main raw materials, and artificial inorganic fibers are produced by centrifugal melting at high temperature. Rock wool fiber is added with an appropriate amount of binder, dustproof agent, hydrophobic agent and other additives, and then collected by the capture belt, pendulum shop cotton, curing, cutting to form a rock wool board with a certain strength. If you are interested in this aspect, you may wish to follow me to further understand the relevant knowledge of the rock wool outer wall insulation board .
Rock wool outer wall insulation board introduction
Rock wool external wall insulation board is special rock wool board for external wall insulation, Class A non-flammable fireproof and heat insulation material, high compressive and tensile strength, low water absorption and moisture absorption, good dimensional stability, no production Thermal expansion or contraction, anti-aging, etc., can be compatible with external wall systems, provide buildings with effective thermal insulation, energy conservation, fire protection, and extreme weather protection.
Yanmian External Wall Thermal Insulation Board is designed and produced specifically for the external thermal insulation and thin plastering system of buildings. It is suitable for the external wall thermal insulation or energy-saving renovation of newly built or existing buildings with dense structures such as concrete or brick walls. The external wall insulation rock wool belt can also be used as a fire insulation belt, and it can be used in combination with the insulation material whose combustion performance cannot reach Class A, in order to improve the fire protection function of the external wall of the building.
Rock wool outer wall insulation board product features

With high-efficiency sound absorption and noise reduction and elastic vibration damping physical properties.
Not hygroscopic, anti-aging, long-term stability of performance.
Lightweight, can be cut and sawed, easy to process.
First, rock wool outer wall insulation board construction process
Rock wool is made of selected basalt and diabase as the main raw material, plus a certain amount of auxiliary materials. The man-made fiber made by high temperature melting and blowing is non-flammable, non-toxic, light weight, low thermal conductivity and sound absorption performance. Good insulation, good chemical stability, long service life, etc. are recognized as ideal insulation materials at home and abroad. Its main types are rock wool board, rock wool felt, rock wool belt, rock wool tube shell and so on.
According to the production process, rock wool board can be divided into settlement method rock wool, pendulum method rock wool and three-dimensional law rock wool. Their characteristics are as shown below.
Second, the performance of different types of rock wool
Glass wool has excellent properties such as fire prevention, heat preservation, and easy cutting. It is one of the most commonly used materials for sound absorption in buildings. However, because the surface of the centrifugal glass wool is not decorative and there will be fiber spills, it must be used in a concealed manner. The construction process of glass wool insulation has the following main points:
1. The glass wool material must have the factory certificate and inspection report form after entering the market. After entering the site, the re-test shall be carried out for installation and construction.
2. After the construction of the keel is completed, a fireproof glass wool insulation layer is laid in the keel sandwich. The exterior thermal insulation wall of the glass wool is composed of a functionally distinct wall structure layer, an insulation layer and a decorative layer, and the exterior thermal insulation wall is made. The main technical key of the body is: the insulation layer and the structural layer are connected.
3. Insulation layer and structure layer connection method: The connection mode between the insulation layer and the structural layer is fixed by 8*120 expansion bolt scheme, 6 expansion bolts per glass wool board, thickness of glass wool board 80, plaster layer 15, for guarantee The bulging bolt anchoring into the structural layer is larger than 25, marking on the drill bit to ensure that there is no negative difference in the thickness of the woven wool board, the construction method is convenient, the fireproof, the safety is reliable, and also the durability is good.
Third, the installation of glass wool board
1. The requirements for the row of glass wool boards: According to the standard whole format (specification: 1200X600), horizontally cross-stitching along the horizontal direction is 1/2 board length. From the corners of the wall, the plates are vertically staggered to ensure that the corners are straight and vertical. Yin and Yang corners are interlocked with glass wool panels. The glass wool of the corners of the door and window openings shall not be spliced, and the entire block of glass wool shall be used to cut and form the incision perpendicular to the board surface. The same insulation board shall be used to paste and fix the corners of the wall.
2. Before the glass wool board is used, design the laying method. Calculate the size of the cutting blanking, the straight edge of the cutting edge should be less than 5mm, the seam is not more than 2mmm, and the gap between the board and the board is bonded with a special tape.
3, glass wool board laying from top to bottom interconnected, glass wool board should be laid in order, when encountering doors and windows openings, should meet the relevant atlas requirements.
4, board surface anchorage and surface treatment
Anchorage: The depth of the installation of the installation of the insulation board anchorage into the structural wall is not less than 25mm. Use Φ8X120mm anchor bolts for anchoring, use electric hammer to drill holes in the outer wall with an aperture of 10mm, hole depth of 120-130mm (including insulation board thickness), and install and sturdy plastic expansion bolts to make the glass wool panels closely contact with the outer wall surface. Combine.
The fastening point should be 1-2mm below the surface of the glass wool board after fastening. Anchor point arrangement: Anchorage points are set in the middle of the four corners and horizontal seams of the glass wool board.
Anchor bolt installation vertical distance 300mm, lateral spacing 400mm, plum-shaped layout, base wall corner encryption to the spacing of 200mm, and meet the design and related standards.
