July 29, 20233 yr Hi all, Hoping someone here can help, I am building a house and have used Dri Therm Cavity Slab 32 insulation. Does anyone know if both faces of the slab are coated for water resistance? Is there a specific face meant to face the exterior wall or does it not matter? I can’t find any information on this online at all. Be grateful for any replies. Thanks 😊
