Non-Settling Wall Spray System
Nu-Wool WALLSEAL is a spray-in-place cellulose insulation applied to the wall cavities of new construction. It is installed to a density of 3.0 to 3.5 lbs. /ft.3 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
Nu-Wool WALLSEAL eliminates voids and air pockets common with other insulation materials, reducing air infiltration and increasing the "Effective R-value" of the wall assembly. Nu-Wool WALLSEAL will save as much as 40% in heating and cooling costs.

Sound Control
Because of its higher installed density and the elimination of voids and air pockets, Nu-Wool WALLSEAL delivers impressive STC ratings in a variety of wall assemblies. STC ratings are available upon request.

Premium Product – Competitive Price
Nu-Wool WALLSEAL delivers increased energy savings and superior sound control. Yet it is competitively priced compared to conventional insulation, 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 Engineered Cellulose Insulation. These safe, non-corrosive fire-retardant chemicals will not harm pipes or circuits. They will not cause harmful fumes or become a health hazard to humans.

Mold Resistant
Nu-Wool Engineered Cellulose Insulation contains an E.P.A. registered fungicide, making the insulation resistant to the growth of mold, even when exposed to conditions favorable to fungal growth.

Vapor Retarders
Vapor retarders are not necessary when using Nu-Wool WALLSEAL. Because of its high installed density (3.0 to 3.5 lbs. /ft.3) and the nature of cellulose fibers, Nu-Wool WALLSEAL minimizes air infiltration and moisture movement. Nu-Wool Company, Inc., the oldest cellulose insulation manufacturer in the world, guarantees the performance of properly installed Nu-Wool WALLSEAL without a vapor retarder.
