Insulation for your ATTICHave you considered cellulose insulation?

Why is insulation important?Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leaking cause energy waste.Source: Typical House Memo, Lawrence Berkeley National Laboratory, 2009 and Typical house_2009_Reference.xls spreadsheet.

Why is insulation important?You probably have less insulation in your home than you actually paid for. 80% According to research by the Insulation Contractors Association of America, nearly 80% of new homes tested had less insulation installed than was paid for.46,000,000 According to industry experts, that’s how many homes in the United States need additional insulation.

Fiberglass insulation– let’s have a lookNotice how the fiberglass insulation has been blown away from the edge of the attic, creating an area with almost no insulation.An example of blown-in fiberglass insulation in a Grand Forks home.

Proper insulation not only saves you money, but also makes your house more comfortable to live in. However, it can be difficult to know where to start. First of all, how do you even know if you need more insulation? And second, what kind of insulation do you need? Not all insulations are equal, in terms of performance and environmental impact.The most popular option is fiberglass insulation. A lot of homes, especially newer ones, have fiberglass insulation. But have you considered cellulose insulation? Cellulose is made of waste paper (up to 85% recycled newspapers).A BETTER OPTION: CELLULOSE INSULATIONHere we have fiberglass insulation on the left, and cellulose on the right. As you can see, cellulose is denser.

MAKE YOUR HOME MORE COMFORTABLECellulose is a very effective insulator. It performs well in extreme weather, when there is a big difference between inside and outside temperatures. It has a higher density than fiberglass, and it can cover difficult spaces like pipes, electrical wiring and other mechanical areas.Fiberglass, on the other hand, is less dense, so air flows through it more easily, which diminishes its insulating value.

HEALTH IMPACTAccording to a report by the Natural Resources Defense Council (NRDC) report:There are substantial and well-documented public health threats associated with fiberglass.No adverse health effects from cellulose insulation have been identified. Cellulose is non-toxic. Biologically, cellulose is innocuous.

Environmental impactCellulose takes less energy to make: the amount of energy required to produce fiberglass is 10 times greater than cellulose. Fiberglass is produced in furnaces that burn natural gas and release greenhouse gases into the atmosphere. Cellulose is produced in electrically-driven mills.Cellulose insulation is the least polluting and most energy-efficient insulation.Cellulose is made from waste paper that would otherwise end up in landfills, and it can be locally produced.Source: Natural Resource Defense Council, a nonprofit environmental membership organization with over 300,000 members worldwide.

Cellulose and fire safetyIn the United States, cellulose insulation must meet the strict flammability standards of the Consumer Products Safety Commission. Cellulose is saturated with fire retardant (accounts for about 20% of weight) during the manufacturing process to insure fire safety.As a result of this fire resistance and as several studies have found, under some fire conditions, cellulose gives building occupants more time to reach safety and fire fighters more time to save the structure.
