As one family discovered, recycled denim insulation is an energy-efficient solution in a temperature-fluctuating environment.
- The warmth factor: Denim insulation has an R-value that is comparable to Fiberglas insulation; it’s available in R-13, R-19 and R-30 batts. The thickness of the denim insulation also allows it to perform well in extreme temperature-change environments.
- The nontoxic factor: Denim insulation doesn’t contain formaldehyde or other volatile organic compounds. And although formaldehyde-free Fiberglas insulation is now available, there are still many Fiberglas insulation products that contain formaldehyde.
- The sound factor: Denim insulation provides better sound insulation than Fiberglas material. According to Bonded Logic’s website, “UltraTouch is made from high-quality natural fibers. These fibers contain inherent qualities that provide for extremely effective sound absorption and maximum thermal performance.”
- The installation factor: You install denim insulation the same way you do Fiberglas, but the cotton fibers of the denim don’t have any of the “itch” associated with Fiberglas. We could handle it without special gloves. Denim insulation, however, has been known to dull cutting tools faster than Fiberglas. Although, at the advice of our local store manager, we used a circular saw and it worked well.
- The cost factor: Denim insulation is priced at about a 15% to 20% premium over traditional Fiberglas insulation. To us, the cost difference was worth keeping harmful chemicals out of our home and reducing landfill waste.
“[It] provides an organic alternative to formaldehyde-laden insulation materials. Recycled denim insulation holds more heat and absorbs sound better than spun Fiberglas insulation. It is also safer to handle. Even when denim insulation is treated with fire retardants and fungicides to prevent mildew, it is still easier to work with and doesn’t require installers to wear protective clothing or respirators.”
