R-10 XPS rigid foam insulation board (2 in. x 4 ft. x 8 ft.)

Owens Corning FOAMULAR NGX F-250 is an unfaced XPS rigid foam board designed to deliver durable R-10 insulation in demanding areas like basements, crawlspaces, exterior foundations, and under-slab applications. It’s lightweight, easy to score and cut, and engineered for moisture resistance to help maintain thermal performance over time.


Key Features:

  • Moisture Resistance: Closed-cell XPS resists water and helps retain R-value even in wet or below-grade applications.
  • Easy to Cut & Install: Lightweight board can be scored and cut without special tools for fast fitting and installation.
  • Versatile Applications: Suitable for interior/exterior use on concrete, plywood, and wood surfaces including basement walls, crawlspaces, exterior foundations, and under slabs.
  • Unfaced Board Design: Unfaced foam board for flexible installation and layering within wall and foundation assemblies.
  • Lower Global Warming Potential Formulation: NGX manufactured with a next-generation blowing agent to significantly reduce global warming potential versus legacy FOAMULAR XPS.
