CLEAN® Cellulose Insulation
What comes with having a CLEAN® home?
Better Sound Control
CLEAN® insulation has excellent sound attenuation characteristics. It creates a seal that doubles as a sound barrier, keeping unwanted noise from traveling through walls and ceilings. A CLEAN® home is a quiet home.
Safer for the Environment
CLEAN® is clean! Through a unique process, newsprint is recycled into today’s highest-quality, best-performing insulation. Using CLEAN® dramatically reduces the amount of newspaper that ends up in landfills. There are no itchy, unhealthy man-made fibers to become airborne, and installation is CLEAN® and easy.
Also, the technology used to produce CLEAN® uses much less energy than the production of conventional insulation. And because CLEAN® homes require less energy for heating and cooling, they reduce consumption of our nonrenewable energy resources.
Higher R-Value, More Comfortable
CLEAN® is the next generation of cellulose insulation. This revolutionary product provides better thermal performance than ordinary insulation.
CLEAN® keeps heat inside in the winter, and outside in the summer — so your home stays more comfortable all year long. CLEAN’s shorter fibers create a superior thermal barrier, preventing heat migration — while ordinary insulation can lose much of its thermal effectiveness in cold weather.
Lower Energy Costs
Recent studies show that cellulose-insulated homes use less energy than homes insulated with conventional batt insulation. That means you’ll spend less to heat and cool your home — much less.
CLEAN® insulation is blown to completely fill around wood framing, electrical wiring and plumbing. The highly efficient, natural cellulose barrier blocks air movement and heat loss.
Superior Fire Safety
CLEAN® forms a thermal barrier that actually repels intense heat, protecting your home and family. Its Class 1 Fire Rating meets or exceeds all local and national building code requirements, making it the safest insulation you can choose.
No Itchy Fibers
CLEAN® is made from natural fibers that don’t irritate the skin or lungs. Its primary ingredient is recycled newsprint, so you can breathe easier — knowing your home is a CLEAN® home.
