SlenderWall composite panel insulated w 2-lbs/ft3 closed-cell spray polyurethane foam
Use of Grace Construction Products’ Monokote Z 3306 Thermal Barrier - Jensen Hughes, 11/26/16
During SlenderWall panel installation, there may be interior building locations which have limited access so that Type X gypsum board cannot be applied to the panel’s stud frame in order to provide the necessary thermal protection. In those instances, a sprayable cementitious fire protective coating like Grace Construction Products Monokote Z 3306 can be applied with appropriate thickness to provide the necessary thermal barrier.
