SLX SHEATHING
SLX Sheathing is an extruded polystyrene (XPS) board that gives you an edge on moisture resistance and thermal performance. With an R-Value of 5.0 per inch of thickness, it is an ideal thermal insulator that increases a home’s energy efficiency. And because it’s made of XPS, the board doesn’t absorb water, allowing it to retain its insulating properties over time. 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 and less waste.
