Lock in Carbon for Life
SANCTUARY® by Greenfiber® is the only major insulation product that is proven to actually reduce global warming potential because it’s made with recycled fibers from trees that lock in carbon for the life of the product. Couple this with low-energy manufacturing and short-haul transportation and it’s clear why cellulose insulation is the responsible, sustainable choice for homeowners and the planet.

Better for Homes. Better for the Planet.
Most insulation materials have significant carbon impacts due to energy-intensive manufacturing, long-distance transportation and high levels of VOCs. Greenfiber cellulose insulation is made with recycled materials and requires less energy to produce, helping reduce its overall carbon footprint.
