Many workers often make mistakes when installing fire barriers. When the height of the adhesive reaches the position where the fire barrier should be, it's crucial to ensure that the rock wool is properly separated from the wall corner. The rock wool should be applied in a direction perpendicular to the fiber orientation. This is because the rock wool used in fireproof isolation belts is manufactured using the pendulum method, which results in lower tensile strength along the fiber direction. By placing the rock wool perpendicular to the fiber direction during installation, the system can fully meet the tensile requirements of the insulation system.
In my experience, following these steps ensures a more effective and durable installation. However, it's important to note that fire barriers are an integral part of the external insulation system. Since different insulation materials are used in this system, after completing the weather resistance test, a wind pressure test must also be conducted. The fire barrier is not just an add-on—it's a critical component of the entire thermal insulation system.
A complete external insulation system typically consists of seven key layers: the base wall layer, anchor bolts, adhesive, fire-resistant insulation board, external insulation material, plastering layer with fiberglass mesh, and the final finish coat. Each of these components must work together seamlessly. For the fire barrier, the insulation board must have the same thickness as the rest of the system and should be installed simultaneously with the external insulation. It should never be left out or added later, as this could compromise the integrity of the entire system.
By following these guidelines, you can ensure a safe, efficient, and long-lasting fire barrier installation. If you're unsure about the process, always consult with professionals or refer to the manufacturer's instructions for best results.
