Specifications for Premium Cellulose Insultation

Nu-Wool is code compliant and meets or exceeds ICC-ES code requirements for thermal insulation. Specifying Nu-Wool on your plans ensures performance and energy savings throughout the life of your structure.

The R-Value of Nu-Wool Premium Cellulose Insulation is 3.8 per inch. Installing Nu-Wool Premium Cellulose Insulation using 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.

Due to its product makeup and density, Nu-Wool Premium Cellulose Insulation can be installed in many unique framing situations and other hard to insulate areas.

Properly packing high density Nu-Wool Premium Cellulose Insulation into cathedral ceilings significantly reduces both the air pockets that cause moisture problems and the need for getting rid of condensation.
