Insul-X Insulation Board

Sto’s Insul-X is an extruded polystyrene foam insulation board used as the continuous insulation component for the company’s Energy Guard systems. It is a 4- by 8-foot board that is scored longitudinally on 16-inch and 24-inch centers so that it is easier to size to commonly used widths beneath masonry veneer, and in full sheets beneath stucco, stone, and thin brick veneer. It is available in three different thicknesses and can be resized to fit any project.
