B2级XPS挤塑聚苯乙烯保温板 25 kg/m³
B2级XPS挤塑聚苯乙烯保温板，密度25 kg/m³，导热系数0.032 W/(m·K)，闭孔结构吸水率低，适用于建筑外墙围护系统、平屋面保温层及地下室外墙防潮保温工程。
// 主要特性
- Low thermal conductivity 0.032 W/(m·K) reduces building envelope heat loss cost-effectively
- Closed-cell XPS structure limits water absorption to ≤1.5% for long-term R-value retention
- Lightweight 25 kg/m³ density enables fast handling and installation on large roof areas
- B2 fire class certified to GB 8624 meeting standard commercial construction requirements
