Which is better blown-in fiberglass or cellulose?
At 3.5 per inch of material, the R-value of blown-in cellulose is 23% better per inch than fiberglass batts! According to research done at the Oak Ridge National Lab, fiberglass loses up to 50% of its R-value in very cold conditions; making cellulose a better choice for homes in northern climates.
Is cellulose insulation any good?
Unlike fiberglass batts with paper backing, it doesn’t burn as you might expect ground up paper to. Despite competing industries stating otherwise, independent testing confirms that cellulose is safe and approved in all building codes. In fact, many professionals consider cellulose to be more fire-safe than fiberglass.
How long does blown in cellulose insulation last?
20 to 30 years
Because it is made primarily of recycled materials, however, cellulose insulation does degrade over time. The typical lifespan is 20 to 30 years, with degradation beginning as early as 15 years after installation. As with other types of insulation, severe weather or outside interference can reduce the lifespan.
