GreenGuard SLX-LG Sheathing

SLX Sheathing is an extruded polystyrene (XPS) board (½",¾",1") with an R-value of 5.0 per inch of thickness. SLX has interlocking shiplap edges that reduce energy-robbing seams and gaps, while also providing an extra barrier against moisture infiltration. Tough film facers on both sides of the board produce greater durability. It is an ideal thermal insulator that increases a home’s energy efficiency. With high moisture resistance, it retains its insulating properties over time.
