XPS foam insulation panels (extruded polystyrene) are a top-tier insulation solution for commercial buildings, offering excellent thermal resistance, moisture resistance, and structural integrity. Here's a detailed look:
What Is XPS Foam Insulation?
XPS (Extruded Polystyrene) is a rigid foam board insulation made by extruding polystyrene plastic into a closed-cell structure. It’s known for its high compressive strength, water resistance, and consistent R-value, making it ideal for demanding commercial applications.
Common Commercial Applications
- Below-grade insulation (foundation walls, basement floors)
- Roof insulation (especially inverted or protected membrane roofs)
- Cavity wall insulation (interior and exterior)
- Under slab applications (resists ground moisture and compressive forces)
- Exterior insulation finishing systems (EIFS)
Considerations
- UV-sensitive: Should be covered if exposed to sunlight.
- Not inherently fireproof: Requires thermal barrier (e.g., gypsum board) per building codes.
- Cost: Slightly more expensive than EPS but offers better performance and durability.
