In the integrated external wall insulation system, new energy-saving materials are often used, and designers have insufficient understanding of the materials, such as their elasticity, resistance to deformation, deformation recovery ability, ability to absorb and release temperature, hydrophobicity, and breathability. The overlapping length of fiberglass cloth should not be less than 10mm, and it should be overlapped vertically. One side should be pressed first, and then the other side. Dry overlapping is strictly prohibited. After laying, it should be flat and wrinkle free, and leveled and compacted with crack resistant mortar.
Regardless of the weather conditions, the integration of external wall insulation plays a crucial role in ensuring the effectiveness of the panels in construction projects. The material cannot be exposed to rain and must be placed indoors. If it is outdoors, it should be covered with an oilcloth. The use of vacuum materials or reducing the thickness of the solid part of the material to eliminate air convection and infrared transmission, reduce the occurrence of heat conduction and convection, and improve the insulation effect of the material is also a major trend in the development of insulation materials.
The overall adhesive force of the integration of external wall insulation will be small. In addition, the finished extruded board must be aged. The foam board without aging has a lot of moisture, which will affect the quality of the entire extruded board. Additionally, micro expansion anti cracking mortar or polymer mortar with high bonding strength, small shrinkage deformation, and certain elasticity can be used. Due to the soft texture of Shandong insulation board, it is recommended that the thickness of anti cracking mortar be between 25mm-30mm.
