Here’s Why Cellulose Insulation is Best for Your Home

Today, as in the past, energy conservation is a vital concern of homeowners and the nation

Since the "Energy Crisis" of the mid 1970s sent heating and cooling bills almost into orbit, homeowners have appreciated the value of a well-insulated home. Although energy costs have moderated, there are still many compelling reasons for energy-efficient homes. In fact, effective energy conservation is one of the factors that has helped hold down energy prices.

Today, as in the '70s, adequately- insulated homes not only save money for homeowners every month, but they also help America conserve vital energy resources for the future, and keep the "demand-pull" factor from forcing energy prices higher.

What Insulation?

When you choose insulation for a new or existing home you will find a number of alternative products available. You must sort through confusing and conflicting claims to find the right insulation material.

  When you know all the facts, however, you'll find that one insulation material stands out from the rest. CELLULOSE! It's the insulation you will want in your home. It's best because...

...Cellulose insulates better. It not only offers more heat transfer resistance per inch than other fiber insulation materials, it also seals the home against air infiltration better than other fiber insulation.

...Cellulose insulation saves more energy when the energy required to make the material is figured into the total energy savings.

...Cellulose insulation makes homes safer by slowing the spread of fire.

...Cellulose insulation makes efficient use of natural resources.

CELLULOSE...insulation that makes sense...and saves you money!

Dollar for dollar, cellulose has more insulating power

"R-value" (an expression of heat transfer resistance) is the standard for measuring insulation performance. At R 3.6 to 3.8 per inch, cellulose insulation is considerably better than most mineral fiber blowing wools. Some materials, such as foam plastics, may have higher R-per-inch ratings, but they are typically much more expensive.

Remember! Compare costs on the basis of the total R-value of the installation, not on the price of individual bags, boxes, or rolls. When you do, you'll find that cellulose insulation gives you the most heat transfer resistance for the money.

Cellulose insulation fills existing walls with fewer voids and stops air infiltration better!

Demonstrations using transparent plastic "walls" inevitably show the superiority of cellulose in filling existing walls with many fewer gaps and voids than mineral fiber materials.

The fibers of cellulose insulation are much finer than mineral fiber blowing wool. When cellulose insulation is run through an appropriate blowing machine, it takes on almost liquid-like properties that let it flow into cavities and around obstructions to completely fill walls and seal every crack, seam, and opening. No fiber glass or rock wool material duplicates this action. Liquid applied foam plastics certainly do, but they cost much more than cellulose insulation.

In new construction, cellulose insulation can be installed in walls using wall-spray or several different dry dense-pack techniques that are even more effective at sealing homes against air infiltration.

Cellulose insulation saves more energy!

In terms of national policy, the energy you save directly at home isn't the only important consideration. Our country has emphasized energy conservation to reduce our dependence on foreign fuel sources and make America less vulnerable to international "energy blackmail." If you are concerned about America's energy independence, you need to understand "embodied energy." Embodied energy is the energy consumed in producing products.

Mineral insulation comes from giant furnaces that gulp fossil fuel to melt sand, slag, or similar materials. Foam plastics are petrochemicals. They are literally made out of energy!

Cellulose insulation is made by processing recycled wood fibers through electrically driven mills that consume relatively little energy when they are operating, and which can be shut down completely with the flip of a switch at the end of the shift — or even for lunch and coffee breaks.

Fiber glass, rock wool, and plastic insulation have from 50 to over 200 times more embodied energy than cellulose insulation.

When you choose these products, you will certainly save on the amount of energy you consume at home, but you contribute to increased overall demand for oil and gas. And increased demand drives up prices!

  When you install cellulose insulation, you are not only choosing to save energy in your home, you are choosing to save energy at the factory where the insulation is produced. By helping reduce our nation's overall energy consumption, you not only reduce our vulnerability to foreign pressures, you are actually helping hold down utility rates and the price you pay for gasoline, plastic goods, and other products that come from oil and natural gas.

Cellulose insulation makes homes safer

All residential structures contain large amounts of wood. Cellulose insulation is the only wood-based construction material that is normally treated for fire retardancy. This treatment makes cellulose insulation one of the safest materials used in home construction.

If a fire occurs, the dense structure of cellulose insulation and its fire retardants slow its spread through the building by blocking flames and hot gases and restricting the availability of oxygen in insulated walls. Scientists at the National Research Council of Canada report that cellulose insulation "in the wall cavity provided an increase in the fire resistance performance of 22% to 55%." Fire roars right through fiber glass. The NRCC study showed that "The fire resistance of an assembly with glass fiber insulation was slightly lower than that of a non-insulated assembly."

Several fire demonstrations have been conducted in which cellulose insulated structures have remained virtually intact while uninsulated and mineral-fiber insulated structures were reduced to ashes.

Cellulose insulation recycles a waste product that represents a significant disposal problem

Cellulose insulation is made from recycled wood fiber, primarily newspaper. One hundred pounds of cellulose insulation contains 80-85 pounds of recycled newsprint.

America's cities are struggling with the challenge of solid waste disposal. Waste paper is a major part of the refuse stream. Today, more and more communities are addressing this problem through "curbside recycling" and similar conservation programs. These efforts work only if there is a demand for recycled products.

The federal government is attempting to create demand through such measures as the Environmental Protection Agency "Guideline for Procurement of Building Insulation Products Containing Recovered Materials" (40 CFR Part 248). Cellulose insulation unquestionably meets every provision of the guideline.

Paper that is not recycled ends up in landfills, where it may contribute to environmental pollution, or at incinerators, where energy is wasted reducing it to ashes, soot, and smoke.

When you choose cellulose insulation, you are making a positive contribution toward solving the solid waste disposal problem. That may help your community hold down taxes or refuse disposal charges. It certainly contributes to a cleaner environment.
