Nu-Wool WALLSEAL® System

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. 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.

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 important in reducing air infiltration and increasing "Effective R-value", is more consistent with the Nu-Wool WALLSEAL system. The builder and the homeowner can actually see the insulation in place and know that all of the areas in a wall are insulated.

  • Resists Mold Growth
    Nu-Wool Engineered Cellulose Insulation undergoes rigorous testing to insure that it will not promote the growth of molds and mildew. "EPA registered fungicide, making it resistant to the growth of mold"
  • Acoustically Superior
    Cellulose insulation is very effective as a sound control material.
Ice dams not only indicate inadequate insulation, they can cause damage to the structure of the house. Heat escaping from the house through poorly insulated attic warms the shingles on the roof, melting the snow, which runs down the roof to the eaves. Since the eaves overhang the house and are cold, the melted snow freezes when it reaches the eaves. When enough ice has formed at the eaves, it begins to stop or dam additional water from draining off the roof. The ice dam eventually grow under the shingles, causing melted snow to enter the ceiling and walls.
Premium Insulation
Many insulation manufacturers claim to make a superior product, but the proof is in the performance. Nu-Wool WALLSEAL is a spray-in-place, energy-saving cellulose insulation. Using Nu-Wool Insulation eliminates the voids and air pockets common with other insulation materials. In fact, you may save as much as 40% on your heating and cooling bills by choosing Nu-Wool Insulation when you build.
Superior Performance
Installed in both attics and walls in residential and commercial structures, Nu-Wool has a high R-Value, offers superior thermal and air-filtration properties, defends against mold growth and even dramatically reduces noise transmission through floors and walls. Nu-Wool WALLSEAL carries the UL and EPA Five Star Energy Program labels. Nu-Wool's contractor training and field support is the best in the industry. Using Nu-Wool Insulation results in energy savings of up to 40% over conventional insulation materials.

Environmentally Friendly
Made from 100% recycled fibers, Nu-Wool is environmentally friendly. Nu-Wool processes over 150 tons of recycled paper each business day – that's the equivalent of 2,550 trees per day!

Nu-Wool is a naturally “green” product and a naturally "green" manufacturer. Over 150 tons of paper are recycled each business day at Nu-Wool – the equivalent of 2,550 trees! Producing Nu-Wool Engineered Cellulose Insulation is more energy efficient than manufacturing fiberglass insulation.

Nu-Wool Engineered Cellulose Insulation vs. fiberglass insulation:
Using Nu-Wool Engineered Cellulose Insulation is more than a smart choice for its comfort and savings benefits, Nu-Wool is environmentally friendly even in the manufacturing process. Fiberglass insulation is made by melting sand and recovered glass in gas-fired furnaces. It takes at least 8,500 BTU’s of energy to produce a pound of fiberglass insulation. Cellulose insulation is produced by processing post-consumer recovered paper through electrically driven mills. Estimates for the embodied energy of a pound of cellulose vary from 150 to 750 BTU’s. Converting this to BTU’s-per-R, it takes at least 40 times MORE energy to make fiberglass insulation than to produce cellulose insulation.

 Since less energy is used to manufacture cellulose insulation, and less fuel is consumed in buildings using cellulose insulation, the atmospheric emissions which contribute to global warming are reduced.
