  • Non-Settling Wall Cavity System

    The Nu-Wool WALLSEAL System is a method of installing Nu-Wool Premium Cellulose Insulation in the wall cavities of new construction. The insulation is installed to a density of 3.0 to 3.5 lbs. per cubic foot and will not settle in the wall cavity. Fibers attach to the sheathing and studs, forming a seamless bond inside the wall cavity.
  • Air Sealing Benefits

    The Nu-Wool WALLSEAL System provides air sealing benefits, making it easier to satisfy energy code air tightness requirements without additional costs for air sealing.
  • Sound Control

    Because of its higher installed density and the elimination of voids and air pockets, Nu-Wool Premium Cellulose Insulation, installed using the Nu-Wool WALLSEAL System delivers impressive STC ratings in a variety of wall assemblies. STC ratings are available upon request. More about Acoustical Performance»
