Energy Savings
- Nu-Wool WALLSEAL is sprayed in place, eliminating the voids and air pockets common with fiberglass insulation. 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 contractor and the customer can actually see the insulation in place and know that all of the areas in a wall are insulated.
- Nu-Wool WALLSEAL is a premium insulation system. Homeowners, developers, builders, general contractors, and architects choosing this system are concerned about energy costs, sound control, and overall comfort. The installers of the WALLSEAL system are factory trained and certified professionals, and are equipped with specialized machines designed for this application. The increased efficiency of the Nu-Wool WALLSEAL system, along with Nu-Wool Premium Cellulose Insulation in the attic, saves homeowners as much as 40%* on heating and cooling costs and dramatically reduces noise from outside the building as well as from room to room.
- Nu-Wool Premium Cellulose Insulation Saves More!
- Independent studies by universities and research labs have shown that on the basis of installed thermal protection performance, a cellulose insulated building will obtain better performance under real-world conditions than a fiberglass insulated building of otherwise similar construction. Savings are on the order of as much as 40%* according to field studies.
