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 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.

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.

Guaranteed Energy Program

Nu-Wool Cellulose Insulation is so energy efficient, we guarantee the heating & cooling bill savings on new homes built with Nu-Wool Insulation. Nu-Wool has been offering guarantees on the energy performance of homes for the past 18 years. In that time, tens of thousands of homes have taken advantage of this program. Nu-Wool Company, Inc. can offer this guarantee because the Nu-Wool WALLSEAL system is consistently superior to other insulation products.

How Does the Guarantee Work?
Each home's characteristics are entered into a computer program that calculates heating loads and the cost of heating based on fuel, weather data, efficiency of the heating system, and the air infiltration factor for that home. If only R-Values were used in the computations, homes with Nu-Wool Insulation would not heat any differently than homes with fiberglass. Through decreased air infiltration, Nu-Wool Insulation has a higher "Effective R-Value." Nu-Wool insulated homes heat and cool more efficiently than conventionally insulated homes.

Nu-Wool, through certified WALLSEAL dealers, offers this Guaranteed Energy Program for new houses insulated with Nu-Wool Insulation at no cost to the homeowner or builder. This energy guarantee not only ensures savings on fuel bills, it can help homebuyers add upgrades to their home without adding costs. Under this program, a homes heating and/or cooling bill is guaranteed for a period of three years. If the energy bills exceed the guaranteed amount, Nu-Wool will reimburse the homeowner 50% of the overage. Builders can use this guarantee as an attractive selling feature to homebuyers.

2 easy ways to qualify for this program:

  1. Get it in writing before building.
    Using detailed blueprints before construction begins, Nu-Wool offers homebuyers a three year guarantee on the amount of energy bills when Nu-Wool is properly installed by a certified Nu-Wool contractor. Key information from the prints will be entered into a computer program that calculates the guarantee amount. A certified Nu-Wool WALLSEAL dealer will verify that the key components of the house were constructed as drawn on the blueprints.

  2. Choose Nu-Wool even after construction starts.
    Have new houses insulated with Nu-Wool Insulation in both the attic and walls. A certified Nu-Wool WALLSEAL dealer can complete the guarantee form, listing the key characteristics of the house. This information will be entered into a computer program that calculates the annual heating and cooling guarantee amount.
