Green insulation for the environmentally conscious

Green insulation for the environmentally conscious

by Kristy Esch

While insulation helps make your house airtight and energy efficient, the pink fiberglass variety found in many homes contains carcinogens that may cause cancer.

Jeff Rogers, owner of N.E. Green Building Supplies and Services in Provincetown, Mass., says choosing a no-formaldehyde cotton batt insulation is a healthy, affordable alternative.

Cellulose shredded newspaper, rigid foam board insulation and spray foams are pricier but also more efficient and green. "There are a lot more options than there were a few years ago, and I recommend talking to a supplier to find the best one," he says.

Angie's List talked to dozens of homeowners and green building experts like Rogers about their favorite insulation brands. Here are the two we heard about most, plus a few others:

Icynene soft foam insulation expands in seconds to 100 times its volume and creates an air barrier system for optimum energy efficiency.
