The Search for Better Insulation Continues
We can all celebrate 25 years of improvements to insulation, but we still have a wish list of seven better products we’d like to see.
by Alex Wilson
When we first started writing about insulation products here at BuildingGreen, the big environmental concern was the ozone-depletion potential of the chlorofluorocarbon (CFC) blowing agents in polyisocyanurate, spray polyurethane foam, and extruded polystyrene. Those products were pretty bad, and we can celebrate dramatic improvements over those 25 years.
Today, there are no insulation materials made that impact the Earth’s protective ozone layer, and some data show that the ozone hole over the Antarctic is beginning to heal.
