Testimonial
"About three months after we had our insulation done by Heritage Weatherization, our natural gas utility had a representative come out to make sure our remote meter was functioning properly. When I inquired as to what prompted the visit, the technician asked if we had some unusually high bills and explained that if unusually high bills register, the company will come out to make sure the readings are correct. Turns out the opposite was true: Our bills had been cut in half, and the company must have noted it and wanted to make sure the drop was in fact valid. Thank you so much for the great work you do!"

Cellulose is kind to our environment
Cellulose Insulation is an 80% recycled product made from engineered wood fiber (cellulose). Obtained primarily from recycled newspapers and other paper products. The energy used to produce cellulose insulation is substantially less than required to manufacture fiberglass insulation.

Cellulose makes homes safer by slowing the spread of fire
Low melting point fiberglass insulations can shrink and melt during a structural fire, thus compromising fire containment. Scientists at the National Research Council Canada report that 'cellulose in the wall cavity provided an increase in fire resistance performance of 22% to 55%. Glass fibre insulation reduced fire resistance because it melted quickly when exposed directly to heat.

Meeting the highest standards set for insulation materials
This industry standard, set by a branch of the Federal Government, is more comprehensive than the Consumer Products Safety Commission regulation, which has strict requirements for flammability and corrosiveness, but does not address other important characteristics that are not safety-related.

Today's cellulose insulation is covered by American Society for Testing and Materials Standard Specifications C-739 for loose-fill insulation and C-1149 for spray-applied self-supporting insulation. Developed and refined over many years through the consensus standard development process of ASTM, the cellulose insulation standards cover several material properties, including:

• Heat transfer resistance (R-value)
• Settled (or design) density
• Critical radiant flux (a measure of surface burning characteristics)
• Smoldering combustion (an assessment of fire resistance within the insulation layer)
• Corrosiveness
• Odor emission
• Moisture vapor absorption
• Fungi resistance
• Adhesive/cohesive strength (spray-on only)

Enter your data into our easy-to-use insulation calculator. By entering in the size of your house, the current and desired R-value you want from your insulation and the cost of your energy, you can see immediately what you would be saving this year and for years to come.

As an added feature, you can also see how your insulation decisions can impact your CO2 emissions.
