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.
The Nu-Wool WALLSEAL System eliminates voids and air pockets common with other insulation materials, reducing air infiltration and increasing the “Effective R-Value” of the wall assembly. Using the Nu-Wool WALLSEAL System will save as much as 40%* in heating and cooling costs.
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.
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.
