California Law Addresses Fire Retardants in Homes

A review of the state's flammability standards could lead to a reduction in the use of fire retardants used in foam insulation

Posted on Oct 16 2013 by Scott Gibson

A measure signed into law by California Gov. Jerry Brown will require state officials to review California's flammability standards for foam insulation, and may ultimately reduce the exposure of homeowners to two common flame retardants.

According to an article posted online at SFGate.com, the state fire marshal and the Building Standards Commission will review current flammability standards and consider whether flame retardants are necessary.

Making Healthier, Greener Foam Insulation

A proposed change to the International Residential Code would eliminate the need for halogenated flame retardants in many applications

Posted on Jan 10 2013 by Alex Wilson

As readers of this blog know, I’ve come down fairly hard on certain types of foam insulation over the years. The downsides include the blowing agents used in extruded polystyrene (XPSExtruded polystyrene. Highly insulating, water-resistant rigid foam insulation that is widely used above and below grade, such as on exterior walls and underneath concrete floor slabs. In North America, XPS is made with ozone-depleting HCFC-142b. XPS has higher density and R-value and lower vapor permeability than EPS rigid insulation.) and most closed-cell spray polyurethane foam and the flame retardants that are added to all foam-plastic insulation to impart some level of fire resistance.
