Nu-Wool Insulation

We use premium Nu-Wool Cellulose Insulation with WALLSEAL to ensure the best quality of insulation and the most energy savings. Before settling for typical foam or fiberglass insulation, be sure to check out our facts about Nu-Wool and the benefits of choosing our insulation services for your project. 

Five Reasons to Use Nu-Wool


Energy costs are going to increase over time, so insulation quality matters.


 Nu-Wool can save as much as 40% on energy bills.


Nu Wool insulation is "Green"  A recycled product 86%.  And nearly zero waste installation. 


Nu-Wool Premium Cellulose Insulation provides superior sound control.


Nu-Wool Premium Cellulose Insulation is treated to resist mold growth, even on the materials it contacts. 

Nu-Wool Air Filtration

"The most common insulation, fiberglass, does not stop air leakage. In older homes, dirty fiberglass is a telltale sign of air movement (it simply collects dirt like a filter). Certain types of insulation, such as dense-packed cellulose and certain foams, can be effective at reducing air flow as well as heat flow.”

Common Misconceptions about Insulation

 You may have heard: Cellulose insulation contributes to mold growth.
FACT: Nu-Wool Premium Cellulose Insulation contains an EPA registered fungicide, which makes the insulation resistant to mold growth, even when exposed to conditions favorable to the growth of mold. EPA registration is achieved only after rigorous testing to ensure that the borate-based fungicide resists mold & mildew.
You may have heard: Cellulose insulation is not fire resistant.
FACT: Nu-Wool Premium Cellulose Insulation contains 100% borate-based fire retardants, enabling the product to not only surpass all federal and industry fire resistance requirements (ASTM C-739, ASTM E-84, and UL 723) but also to achieve 1, 2 and 3-hour firewall ratings in at least 50 UL-approved designs.
You may have heard: Cellulose insulation costs more than fiberglass.
FACT: Fiberglass insulation is sometimes less costly to install than cellulose insulation. However, the initial cost savings is lost within the first 1-2 years due to higher utility bills. The cost continues to rise as homeowners with fiberglass insulation pay consistently higher heating & cooling bills throughout the life of the house. Unlike fiberglass, Nu-Wool Premium Cellulose Insulation has a higher density and is proven to fill in the air pockets and voids within walls and ceilings to reduce air leakage. This not only provides a much more comfortable home, but also reduces the cost of utilities throughout the life of the building.
You may have heard: Cellulose insulation settles inside the wall.
FACT: Because Nu-Wool WALLSEAL is installed at a density of 3.0-3.5 pounds per cubic foot using a controlled water fog, it adheres to the studs, plates, and sheathing inside the wall cavity. When properly installed, Nu-Wool WALLSEAL will not settle over time.
You may have heard: Foam insulates better.
FACT: Open cell foam has about the same R-Value as Nu-Wool Cellulose WALLSEAL per Inch (3.8), meaning Nu-Wool insulates at the same rate. 
You may have heard: Foam seals out moisture and stops moisture accumulation
FACT: Open cell foam with the skin layer compromised (a puncture or shaved) will absorb water similar to a sponge. As well, anytime you have less than about 2” of foam in this area (west central Ohio), you may get condesation on the foam, which is moisture accumulation.
You may have heard: Foam doesn’t shrink.
FACT: Most foam specs in the fine print even say it will shrink by .5% and what they don’t tell you is that with closed cell foam, many times it is so rigid that as the stucture moves, the bond will break free and leave a crack.
