The rock wool applies quality basalt as the raw material and the basalt is definitely non-combustible.Rock wool sandwich panel building envelopesystem can greatly reduce the occurrence of fire accidents.


Take the 50 mm thick rock wool sandwich panel for example and the panel can absorb the sound over 30 db/m2.Widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.


Super flame retardation


The rock wool sandwich panel adopts the top-rated rock wool and durable steel sheets which have outstanding properties, such as anticorrosion and anti-freezing.


The Italian production line is totally automatic and all the procedures are finished on the production line, such as the filming, the profiling of steel sheets, the cutting of rock wool, the conglutination of the rock wool and steel sheets, the cutting of the finished panel and the stacking.


On the basis of non-combustible rock wool, the unique design of polyurethane seal gives the rock wool an extra protection from being destroyed by water.


No carcinogenic content is inspected in the rock wool sandwich panel and the thermal conductivity of the rock wool is less than 0.035w/m.k, so it is safe to use rock wool sandwich panels as insulation building materials.
Easy and quick installation


Without deliberate destruct ions, the rock wool sandwich panel can be used for over 25 years.

Technical parameters

Effective width 1000mm
Thickness 50mm, 75mm, 100mm
Length According to customer's request, normal less 11.8m
Color Blue, red, white gray,as customized
Surface Material Galvanized ,stainless steel, aluminum steel
Steel Thickness Nomal: 0.4-0.7mm

Upper and lower surfaces: galvanized color steel, thickness of 0.4-0.7mm. According to the specific requirements of customers, can be colored galvanized steel or galvanized steel. After the first steel roll forming machine in rock wool factory complex.
Rock wool core material: the density of 120kg / m3; rock wool block staggered laying, the fiber direction perpendicular to the sandwich is still under the surface, and closely Detailed enrich the entire vertical and horizontal surface movement plate. And wool and, through the high intensity blowing agent connections between the lower plate is formed integrally between rock wool blocks. Sophisticated production process to ensure to produce high density rock wool insulation between the body and the metal plate inside the inner wall of strong adhesion, so that the rock wool sandwich panel has good stiffness.


Manufacturing technology

Polyurethane sealing side rock wool sandwich panel used the assembly line production process, give full play to the rock wool core material of the unique properties, such as fireproof, sound-absorbing, and good use polyurethane excellent waterproof performance, and avoids the shortcoming of rock wool bibulous absorb moisture, let polyurethane, rock wool board got fully the advantages of integration, to carrier to save, thus effectively extend the service life of the product.



It has the following characteristics
1) seal, not bibulous. Effectively prolong the service life of the product.

2) beautiful performance: the interface design with European standards, and smooth, round shape, board face level off beautiful, seams, reliable strength, effectively prevent the formation of hot and cold bridge.

3) strength good: polyurethane sealing rock wool on both sides with two layers of steel plate and core material bonding into a whole, to work together, plus the roof plate surface wave pressure type, its overall stiffness is far better than the pressed powder rock wool, glass wool cotton) the site of the composite plate. Sandwich board by fitting and purlin fixed, greatly improving the overall stiffness of roof, roof to strengthen the overall work performance.

4) reasonable hooking way: rock wool board connected by hidden-interlocking roof polyurethane sealing side, to avoid the roof plate joint leakage hidden trouble, save the dosage of accessories.

5) fixed firmly reasonable methods: polyurethane seal rock wool roof plate self-tapping screws on both sides set up between the two plate seam roof plate wave location, and the use of special waterproof structure, avoid to produce waterproof vulnerabilities.

6) short installation period, polyurethane sealing side rock wool sandwich panel, due to the site without secondary processing, the average daily installation area of 600 ~ 600 square.

7) anti scratch protection: rock wool sandwich board in the production of polyurethane sealing side, can paste polyethylene adhesive protective film on the surface. To avoid the transportation and installation process of the steel plate surface coating from scratch or wear.


1. You need to ensure that the heat preservation facilities and pipeline surface drying, there is no leakage. rock wool board and rock wool felt have to butt joint closely in order to let the heat loss minimum,

2. It is best to use metal or plastic package on its surface when the rock wool products for outdoor insulation or where vulnerable to mechanical wear, and pay attention to the joint tightness and sealing. If used in cold areas, it must be combined with a layer of moisture proof layer on the surface.

3. The polyurethane rock wool insulation board must be combined with appropriate outer sheath when the temperature is greater than 200 degrees Celsius, and it won't make the product thickness and density of change.

4. It must be combined with the heat preservation nail, and to guard against when used in large diameter or wall rock wool insulation products equipment and the temperature is greater than 200 ℃.
