We are kicking off the 2009 edition of the Healthy Building News with a new feature called Did You Know? We got the idea for this new column through research for our building materials evaluation project, Pharos, which regularly reveals things that may not yet be on your green radar, or that you suspected, but hadn’t been able to confirm. Did You Know? will alternate with my regular column on emerging market and political trends in the green building industry.
In this issue . . .
Did You Know ... that fiberglass batt insulation can release potentially hazardous levels of a known cancer-causing chemical?
LEED and many other green building rating systems reward the avoidance of wood products with added formaldehyde, but don’t address the formaldehyde-based binders used in most fiberglass batt insulation. An HBN research memo reveals that fiberglass insulation may expose you to potentially dangerous levels of formaldehyde.
The good news? An increasing number of batt insulation products are now available with no added formaldehyde.
