Icynene: Ozone-friendly, Open-cell Polyurethane

We first learned about Icynene at the First Annual Conference on Alternatives to CFCs and Halons in November 1990. At that time it was a tiny Canadian company (founded in 1986) with a type of foam insulation that had no harmful effects on the Earth’s stratospheric ozone layer. Company founder Graeme Kirkland recognized early on that Icynene had significant environmental benefits over its spray-polyurethane cousins, but it has taken him a long time to convince a conservative U.S. insulation industry to embrace his product.
