When using construction cement foam board, it's essential to pay close attention to key details. One of the most important factors is ensuring that the external insulation material is impermeable while maintaining good permeability within the insulation system. This helps prevent freezing and thawing damage, which could lead to structural issues like bricks falling off. Additionally, improving the fire resistance of the external thermal insulation system is crucial. In case of a fire, the system must not develop cavities that could compromise its integrity, especially when tiles are placed on the surface and subject to gravitational forces.
Cement foam boards are typically installed on the exterior of the main building structure, meaning they are directly exposed to various stresses such as thermal expansion, moisture, wind pressure, and seismic activity. To ensure long-term stability, proper reinforcement measures must be in place. This helps maintain the overall performance of the building and the insulation system, reducing the risk of problems like veneer cracking, tile drumming, or even detachment.
The surface tiles are applied to the outer wall, and the cement foam board should be integrated into a solid structure to protect the insulation layer. The surface layer needs to be reinforced to increase its strength, ensuring it meets required standards for durability and safety. Proper adhesion and compatibility between materials are also vital to avoid future failures.
It's also important to consider the performance characteristics of aluminum silicate products used in the system. Factors like folding ratio, bond strength, weathering resistance, and the ability to match the deformation of the entire insulation system play a significant role in managing stress from temperature changes, moisture, or other environmental factors. These elements help the system expand and contract without causing damage over time.
