When shopping for extruded polystyrene xps foam board as exterior wall insulation materials, you can consider the following key tips:
1. thermal insulation performance indicators: the main role of extruded polystyrene xps foam board is thermal insulation, so you need to pay attention to its thermal insulation performance indicators, such as thermal conductivity (λ value). the smaller the λ value, the better the thermal insulation performance. According to the climatic conditions of the region and the need for thermal insulation effect to choose the appropriate λ value.
2. Material density: density directly affects the compressive strength and durability of extruded polystyrene xps foam board. Generally speaking, the higher the density, the greater the compressive strength and durability, but at the same time the price may be slightly higher. Choosing the appropriate density can be decided according to the specific project needs and budget.
3. Waterproof performance: external wall insulation materials need to have good waterproof performance to avoid moisture intrusion leading to a decline in insulation effect or material aging. Extruded polystyrene board usually has good waterproof performance, but in the actual choice still need to confirm its waterproof performance indicators.
4. Environmental performance: environmental performance is an aspect of the current society is paying more and more attention. Selection of extruded polystyrene xps foam board in line with national or regional environmental standards, to ensure that its production and use of the process of less impact on the environment.
5. Convenience of construction: the construction method of extruded polystyrene xps foam board should match the project demand and the technical level of workers. Understand its construction methods and characteristics to ensure that it can be installed and adjusted smoothly.
6. Supplier reputation and after-sales service: choose suppliers with good reputation and after-sales service to ensure that they can provide technical support and solve problems in time.
Comprehensive consideration of the above points can help you choose the extruded polystyrene xps foam board with superior performance and suitable for the needs of the project. In practice, according to the requirements of the specific project, you can combine all aspects of consideration for detailed evaluation and selection.
