Paint-On Insulation: Is It Truly Green?
Non-Toxic and Environmentally Friendly Insulation
Winter is here, and if that utility bill is high, you are probably already troubleshooting problem areas of your home. One of largest contributors to drafty rooms is a lack of insulation. Insulation is designed to stop air passage through ceilings, walls, and the floor. The intention is to keep the right air where you want it in each season. Obviously, the windows and heating source are also important to maintaining an overall energy efficient program, but having the right insulation is a key factor.
In existing homes, it can be difficult to go back and insulate after the fact. If attic space allows, you can blow-in insulation. Under-floors and in-between walls can be difficult as well. Even with your best efforts, there is bound to be some location that is hard to reach. What if you had a product that you could apply from the exterior?
Sound a bit like science-fiction? SFGate highlighted the ingenious concept of Nansulate this past November. It is a paint-on insulation that suspends specially engineered particles with low-conductivity in an acrylic base. The particles are water-resistant, making the paint a weapon against mold and mildew. Unlike traditional fiberglass insulations, this new product is non-toxic and environmentally friendly.
So how green is this product? The company promotes it as a major breakthrough in green endeavors. Not only does it contribute to creating more energy efficient homes, but they also make this statement regarding the safety of the ingredients: "Nansulate® coatings contain none of the ingredients contained on the EPA listing as Class I or Class II Ozone Depleting Substances, nor do they contain any ingredients on the listing for Global Warming Potential (GWP) that are non-ozone-depleting." The company is anxious to become accepted into the green marketplace. "We are pleased to see that our Nansulate coatings are becoming a brand name in the sector of Green Nanotechnology," stated Francesca Crolley, VP Operations & Marketing.

Sounds like a pretty good idea, but is it affordable to the average homeowner? Surprisingly, it is actually quite affordable. At $66 for 150 sqft of coverage, it is an inexpensive alternative to other forms of insulation. Especially if you take into account the ability to avoid opening up walls or crawling under houses. The paint can be applied with a brush, sprayer, or roller. It is applied to walls, windows, pipes, and water heaters, and can even be applied over existing paint.
Because this is a fairly new product and its composition is so different from traditional insulation materials, it is hard to do a straight-across-the-board comparison between the two. So far, however, those who have already used it report a 20-40% savings on their utility bills.
A relatively new product, the company is working hard to bring awareness to its presence. I, like many, was initially skeptical. It sounds a bit too easy to be effective. They offer several case studies to promote its efficiency, but each of us will probably have to try it firsthand before we are believers. It definitely sounds like it is worth trying-out. Fairly easy to install, why not see how it can help your energy efficiency this season?
