Fire-resistant and thermal insulation boards for exterior walls cannot be used alone. To ensure they adhere firmly to the wall, it is not only essential to take basic precautions but also to be mindful of certain issues during the construction process. Otherwise, insufficient adhesive tensile strength can lead to the detachment of the fire-resistant and thermal insulation boards, potentially causing hazardous accidents. Let's take a look at the precautions to be taken during the installation of exterior wall fire-resistant and thermal insulation boards.

During the process of installing fire-resistant and thermal insulation boards on the exterior walls, the installation of the internal and external corners should be prioritized, followed by the sequential installation along both sides. Consider the positions of door and window openings as well as expansion joints when selecting the board sizes, and choose a single specification for the same project unit.

2. External fire-resistant thermal insulation boards should be adhered to the exterior wall. On other floors, adhesive should be applied along the edges on the back of the boards, with a width greater than fifty millimeters. The core of the board can be coated using either spot application or strip application methods, and the adhesive area rate on a single board should be greater than forty percent.

3. The manufacturer of exterior fire-retardant insulation boards explains that the boards should be粘贴 in a staggered manner, with the vertical joints offset by half the length of the board, alternating between the male and female corners.
