Foamular NGX 1.5 in. x 14.25 in. x 4 ft. R-7.5 XPS Project Wall Panels Rigid Foam Board Insulation

Owens Corning FOAMULAR NGX Project Wall Panels are extruded polystyrene (XPS) boards designed to fit in 16 in. on center wood stud cavities providing an R-7.5. They are great for insulating unfinished basements and garage walls (must be covered by a 15-minute thermal barrier like gypsum drywall). The Owens Corning patented Hydrovac process technology makes the unique closed-cell structure of FOAMULAR NGX XPS highly resistant to moisture, strong, easy to cut and shape and it remains dimensionally stable over time.
