Introduction
Polyurethane edge-sealing rockwool sandwich panels, also known as polyurethane side-sealed rockwool sandwich panels, fully utilize the thermal insulation properties of polyurethane and the fireproof performance of rock wool, making them a new type of composite panel that combines thermal insulation and fire resistance.
Polyurethane edge-sealed rockwool sandwich panels are made with two layers of high-quality colored coated steel plates or other precisely pressed metal plates as the panels. After being rolled and formed, the rock wool/glass wool is flipped 90 degrees after being cut into strips (so that the fibers are perpendicular to the upper and lower steel plates).
Through high-strength, high-viscosity, and high-fire-resistant adhesives, high-quality rock wool/glass wool is firmly bonded to the metal panels to form beautiful, flat, and rigid building panels. The finished polyurethane edge-sealed rockwool sandwich panels have excellent fireproof, thermal insulation, and environmental protection properties, providing a good choice for industrial building enclosure systems.

Advantages
Excellent fireproof performance
Good thermal insulation and heat preservation
Significant sound insulation and sound absorption results
In terms of material, polyurethane edge-sealed rock wool panels have two more polyurethane edge seals than ordinary-colored steel rock wool sandwich panels. In terms of performance, polyurethane has better bending resistance and load-bearing performance, so polyurethane edge-sealed rock wool panels are firmer and less prone to delamination than ordinary colored steel sandwich panels and have better thermal insulation performance.

Testing Quality
The first two dynamic test images visually demonstrate the flame-retardant properties of our cold storage panel core material. We simulated a real-world fire using a standard flame source, continuously burning the panel surface. As you can see, the panel didn't burn violently. Instead, it carbonized its surface, forming a dense char layer that effectively blocked the flames from penetrating deeper. This is the most critical step! Once the fire source was removed, the open flames on the panel extinguished themselves within a very short time (approximately 2-3 seconds), with no signs of sustained combustion.
The third dynamic test image is a transparent statement about our "closed-cell rate." Our closed-cell rate of over 98% means that the vast majority of the countless cells within the panel are independent and sealed. These countless tiny "vacuum compartments" together create an impenetrable barrier, completely isolating moisture and water vapor.
