That's why it is a national regulation requirement that both the comprehensive thermal conductivity coefficient and heat storage coefficient of the walls must meet the standards. EPS or XPS thin coat systems fully meet the requirements. Strength: The strength referred to here should be tensile strength. There is a relationship between the density and tensile strength of polystyrene boards. For exterior wall insulation extruded boards, the general EPS has a tensile strength of 110-120 KPa with a density of 18 Kg/m3, and about 140 KPa for a density of 20 Kg/m3. The density of XPS is typically from 25 Kg to 45 Kg, with Ningbo extruded boards having strengths from 150 KPa to 700 KPa or higher. (Provided that the thermal conductivity coefficient is around 0.03.)




Application Range: Building roof insulation, steel structure roof, building wall insulation, building ground moisture control, square ground, ground frost heave control, central air conditioning ventilation pipes, etc. Performance Comparison: The exterior wall insulation systems of thermal insulation boards mainly include: EPS board exterior wall insulation system, XPS board exterior wall insulation system, with performance comparisons between the first and second systems. Insulation and heat preservation performance: The thermal insulation performance of EPS and XPS increases gradually with the same thickness. EPS is 0.041, B1 grade extruded board, and XPS is 0.030.




Due to its inner closed-cell structure, it exhibits excellent moisture resistance and maintains good thermal insulation properties in damp environments. It is suitable for buildings with special thermal insulation requirements, such as cold storage facilities, as well as for façade materials like tiles or stone. XPS boards have high compressive strength, making them resistant to cracking and damage during construction. This is attributed to the high compressive strength of XPS boards. The performance of XPS boards is superior; the typical service life of general XPS boards is 60 to 80 years, far exceeding that of EPS boards. After more than a decade of development in China, XPS boards have gained widespread attention and promotion.
