DRICORE Insul-Armor provides insulating power in a subfloor. It is engineered with 100 percent inorganic EPS foam that is lightweight and durable enough to hold up to 3,650 pounds per square foot while weighing less than 2 pounds per panel. The product’s Air Gap Technology helps protect against moisture, mold, mildew and small water leaks. It makes floors feel warmer with an R-value of 4.1. The product’s 23 1/4- by 47 1/4-inch size with tongue-in-groove design doesn’t require power tools to install. It is engineered to protect all hard-surface floors, including LVT, LVP, laminate and engineered hardwood. DRICORE Insul-Armor features a limited 25-year warranty.
