When thermal insulation is used for external walls, fire-resistant thermal insulation materials must be selected to cause casualties and property losses due to the spread of fire. In the process of building construction, it is a very important choice not to choose some non-fireproof insulation materials because of cheapness. Sometimes we also notice the fire on the outer wall, which should also attract our attention, so what details should we pay attention to when doing the construction of the outer wall? Let’s discuss it today.

 

The thermal insulation materials used for exterior wall construction in China are graphite modified cement-based thermal insulation boards and rock wool thermal insulation boards. Graphite modified cement-based insulation board has better fire performance than rock wool insulation board. Rock wool insulation board is still a traditional insulation material, mainly composed of mortar and accessories to form an external wall insulation system. In addition to the fireproof performance of the thermal insulation material itself, the construction requirements and construction plans must also comply with the fire protection regulations, and corresponding measures must be taken to prevent fires. We recommend using regular products with relevant testing and certificates to ensure that every construction item is of high quality and meets fire protection requirements. However, we have also seen fires on external walls from time to time. Products that do not meet the fire protection requirements cannot be used, and some substandard products cannot be used because they are cheap. The fire protection requirements must be A-level non-combustible, and B1-level or B2-level products cannot be used to avoid fire or potential safety hazards caused by operational errors.

 

As a fireproof building material, rock wool insulation board can be used in external wall insulation, but if rock wool board is used as external wall insulation board, it needs to be of higher quality and higher density. Try to use basalt rock wool board, which has better fire performance.
