What is the Nu-Wool WALLSEAL System?

The Nu-Wool WALLSEAL system is a spray-in--place cellulose insulation product that is applied to the wall cavities of new construction. Nu-Wool WALLSEAL is an insulation product high in R-Value, made by Nu-Wool Company, Inc., a business with over 50 years of proven performance standards.

How is Nu-Wool WALLSEAL different from other insulation materials?

Nu-Wool WALLSEAL is sprayed-in-place, eliminating the voids and air pockets common with other insulation materials. Density, or weight per cubic foot, which is necessary in reducing air infiltration and increasing effective R-Value, is more consistent with the Nu-Wool WALLSEAL system. The contractor and the customer can actually see the insulation in place and know that all of the areas in the wall are insulated.
