How Applegate Cellulose Insulation is Safe!

Fire Safety 

Applegate Cellulose Insulation is one of a few building materials used in homes that is commonly treated with fire retardants. Applegates' premium products go the extra mile with fire retardancy by using a unique, two-stage process that injects both dry and liquid (BurnBarrier) fire retardants to saturate the cellulose fibers. The use of our propriatary BurnBarrierfire retardant results in an exceptional insulation that meets and often exceeds stringent fire safety standards, helping protect you and your family. 

Applegate Cellulose Insulation's ability to add fire resistance is not limited to fire retardants, it also limits the amount of oxygen which can support a fire. Applegate Insulation gives occupants additional time to reach safety during a fire, unlike fiberglass which can actually decrease the amount of time a fire needs to destroy a wall. That's right! The National Research Council Canada wrote, "...the fire resistance performance of an assembly with glass fibre insulation in the wall cavity was slightly lower than that of a non-insulated assembly." Applegate Cellulose Insulation greatly restricts the amount of oxygen available to support combustion, preventing a chimney effect in which hot air and fire can race up a wall to a ceiling or attic where the fire can endanger the entire home.

Air Quality 

Many common building materials release and / or contain fairly dangerous substances. For example, particleboard emits formaldehyde. Carpeting outgasses volatile organic compounds. Fiberglass insulation is listed as a potential carcinogen, containing respirable glass fibers, and potentially formaldehyde. Applegate Insulation has none of these concerns. In fact, Dr. Arthur Furst, one of the world's foremost toxicologists, states, "In essence, the dusts from cellulose insulation materials can be considered as any household dusts... Biologically, cellulose is innocuous."

Donna Reynolds of the American Lung Association says, "Poor indoor air quality affects millions of


American Lung Association of Virginiaworkers' health, decreases productivity, and increases the amount of sick leave." Perhaps that's why the American Lung Association of Virginia (ALA-VA) chose Applegate Insulation to insulate their 12,000 sq. ft., Breathe Easy® office complex. Applegate helps ALA - VA realize their primary goal of minimizing indoor air pollutants.

Take a look at some of the health concerns and how Applegate stacks up against traditional fiberglass.

Mold SporesMold spores are everywhere. They're found in nearly every environment—inside and outside; can be carried in through windows, doors and HVAC systems, on people's clothing or pets; and are ready to rapidly reproduce if given appropriate conditions. In order for those mold spores to be activated and grow, three things must be present: correct temperature, nutrients/food, and moisture. Two of these components are a part of most living spaces. Most individuals like to keep their thermostat between 65F and 75F - a perfect range for comfort. Unfortunately, mold likes that temperature range, too, and can survive at temperatures between 47F - 120F. Furthermore, our buildings are built and furnished with the organic materials that mold devours for food; carpet, drywall, ceiling tiles, wall paper—even dust—are all materials mold uses for nutrients.

Moisture, however, can and should be a controllable element. Therefore, mold problems are actually moisture problems. In the EPA's

guide to Mold Remediation in Schools and Commercial Buildings, the first question they ask someone to consider when assessing a mold occurrence is: "Are there existing moisture problems in the building?"

In a paper entitled "Mold: Causes, Health Effects and Clean-Up", Joe Lstiburek, a well-known building scientist, emphasizes the correlation between moisture and mold, "Mold requires water. No water, no mold. Mold is the result of a water problem. Fix the water problem. Clean up the mold. And you have fixed the mold problem. To avoid mold problems, avoid water problems."

The good news is that Applegate does not cause moisture problems. In fact, it helps prevent them! Applegate's density and custom fit aid in controlling air infiltration and exfiltration. Other insulations may permit moisture to piggyback its way into the walls on humid air; once inside the structure it may condense and gather on cooler surfaces, jumpstarting the mold to life.

Cellulose Insulation Saved My House

The local fire department may have saved his house from burning to the ground, but it was the insulation that gave Bob Douglas and his family time to escape an electrical fire that had begun in his attic in South Grafton, MA.

“It was determined to be an electrical fire that smoldered close to eight hours before my smoke detectors went off and alerted my wife and I at 4:45 in the morning,” said a relieved Douglas. “We all got out safely, and the damage to my house was minimal.”

Cellulose has long been known to have superior fire-resistance to more commonly installed fiberglass insulation. In fact, there are now numerous fire-related construction assemblies for homes and commercial structures that call for the use of cellulose insulation. Its dense structure and fire retardant additives block flames and hot gases while restricting the availability of oxygen, thereby slowing a fire’s spread through a building.

In Douglas’ case, the fire never erupted into actual flames until the firemen opened up his roof and oxygen made its way in for a few short seconds before water from their hoses extinguished the blaze.

According to Douglas, cellulose insulation now has an advocate for life.

“I give credit – first and foremost – to the Grafton Fire Department for their incredible response time, and second, to the cellulose insulation I installed during a renovation three years ago,” said Douglas. “Hopefully, what happened to me will convince another homeowner to make a decision that might save his house and family!”
