If your attic has enough insulation and proper air sealing, and your home still feels drafty and cold in the winter or too warm in the summer, chances are you need to add insulation to the exterior walls. It may be worth the cost—especially if you live in a very cold climate. When you replace the exterior siding on your home, consider insulating your exterior walls at the same time.

WHAT IS DENSE PACKING WITH CELLULOSE INSULATION?

Dense-packed cellulose is a highly efficient option for insulating exterior walls. It insulates better than the average fiberglass batt (R3.5-3.8/inch), and slows air flow through walls making your house cheaper and easier to heat and cool. In addition, the high density of packed cellulose provides you with a better sound barrier than batt insulation. Cellulose insulation is manufactured with borate, which is a fire retardant that also resists mold and and insects. In fact borate, in small amounts, has been determined to be largely harmless.

As well, cellulose insulation is considered to be more flame resistant than both fiberglass and mineral wool batts. The dense packed method in and of itself adds to the flammability resistance. Consider how hard it is to burn a phone book versus burning a single sheet of paper. The lack of air gaps and air circulation make burning a phone book much more difficult than burning a single sheet.

CELLULOSE INSULATION - "Greenest" of the Green.

If you are looking to insulate using the greenest of options, cellulose insulation is probably for you. It is manufactured using upwards of 85% recycled materials, acts as carbon storage and requires significantly less energy to manufacture than any batt insulation on the market.


Cellulose Insulation is one of the greenest products in the world.


Made from a renewable natural resource which diverts waste from landfills, Cellulose insulation not only limits greenhouse gas emissions during manufacturing, but also prevents waste paper from releasing environmentally harmful gases as it decomposes.


Cellulose Insulation fire retardants are also well-characterized and regarded as nonhazardous. The toxicity of borate, a common fire retardant in cellulose insulation, is virtually identical to that of table salt. Other cellulose insulation ingredients are equally benign.

    Beneficial Insulation has completed evaluation and insulation of three residential homes for us. Two of these homes are in Wisconsin and one is in northern Illinois where my mother lives.

    We have a cape cod that was had a lot of air leakage and extremely uncomfortable in the upstairs bedrooms due to poor insulation in the attic. With air sealing and insulating the side walls our home is much more comfortable. The crew was very professional.

    Thank you very much for all your hard work. After hearing and thinking bad things about insulating contractors, it was a pleasure to do business with Beneficial Insulation Solutions. I have known for a long time that I needed more insulation in my attic.

  • Jennifer & Trent

    A little over a year ago, you installed quite a bit of additional insulation in our home. This note is just to say thank you for your excellent work and solid recommendations.

    In November we hired Beneficial Insulation Solutions, LLC to fully insulate our home. Owner Cliff Wakefield thoroughly explained the various options and procedures to us.

    Thank you Cliff for saving our gutters and a possible head trauma.
