Making Healthier, Greener Foam Insulation

Posted on April 25,2015 by AlexWilson in EPS

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 (XPS) 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.

Insulation to Keep Us Warm — Not Warm the Planet

Posted on April 25,2015 by AlexWilson in climate change

I’ve been pretty vocal about a big problem with some of our most common insulation materials: that they are made using blowing agents that are highly potent greenhouse gases. All extruded polystyrene (XPS) and most closed-cell spray polyurethane foams (SPF) are made with HFC (hydrofluorocarbon) blowing agents that have global warming potentials (GWPs) many hundreds of times greater than that of carbon dioxide. (My apologies for contaminating this column with so many acronyms!)

New Blowing Agent Addresses Climate Impact of Foam Insulation

Posted on April 25,2015 by Tristan Roberts in blowing agents

Honeywell has introduced two new blowing agents that could dramatically reduce the global warming potential (GWP) of a variety of foam insulation types. Marketed under the brand name Solstice, they are designed to be “drop-in” substitutes for blowing agents currently used to manufacture insulation for both buildings and appliances, including extruded polystyrene and closed-cell polyurethane foams.

What Is a Deep Energy Retrofit?

I recently heard that a good blog is like a red party dress: long enough to cover the important parts, but short enough to maintain one's attention. By that measure, the Green Architects' Lounge podcast episodes are like royal wedding gowns with long trains that flow down the aisle. This is great if you like wedding gowns, but ... Because we feel that many short dresses are better than a single long one, we've decided to divide our episodes into smaller, more manageable parts, and release them with greater frequency. (Time to switch metaphors...)
