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.

Energy Saving

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 on heating and cooling costs.* Read more»

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. Read more»

Premium Product – Competitive Price

Nu-Wool Premium Cellulose Insulation delivers increased energy savings and superior sound control, yet is competitively priced, making it one of the best values in the insulation market.

Effective, yet safe

Borate-based fire retardants are incorporated in the manufacturing of Nu-Wool Premium Cellulose Insulation. These non-corrosive fire-retardant chemicals will not harm pipes or electrical wiring,  cause or contain harmful fumes or become a health hazard to humans. 

A Naturally "Green" Energy Saving Product.

Nu-Wool Premium Cellulose Insulation is made from recycled paper. 100 pounds of Nu-Wool Premium Cellulose Insulation contains 85 pounds or more, of recycled paper, primarily newsprint. The manufacture of Nu-Wool Premium Cellulose Insulation uses at least 10 times less energy than it takes to manufacture fiberglass insulation. In addition, Nu-Wool Premium Cellulose Insulation will save in heating and cooling costs.* By eliminating voids and air pockets common with other insulation materials, reducing air infiltration and increasing the "Effective R-Value" of the wall assembly, Nu-Wool Premium Cellulose Insulation helps control sound, provides superior thermal properties, and is environmentally friendly, even in the manufacturing process. Read more»
