STYROFOAM WALLMATE slotted extruded polystyrene insulation is designed as a quick, easy-to-install and durable option for insulating and finishing the interior of basement walls. It has an R-value of 5.0 per inch and resists moisture, helping to keep your basement warm and dry. It features slotted edges on the long sides of the boards. When butted together, the slotted edges form a slot between boards that accommodates a wood nailing strip, which is used for attaching the boards to the wall. It also provides a nail base for drywall — avoiding costly framing.
