High-Performance Extruded Polystyrene (XPS) Insulation for Superior Energy Efficiency

Durable & Moisture-Resistant XPS Insulation for Homes & Commercial Buildings
Extruded Polystyrene (XPS) insulation is a rigid foam board designed for high-performance thermal insulation in walls, foundations, and roofing systems. Its closed-cell structure provides:
- Superior moisture resistance, preventing water absorption and mold growth
- High compressive strength, making it ideal for load-bearing applications
- Long-term thermal performance with a stable R-value over time
- Easy installation for both residential and commercial construction projects
Commonly used in below-grade foundations, slab insulation, and exterior wall assemblies, XPS insulation enhances energy efficiency and protects buildings from moisture-related issues.
