Lapolla improves spray foam yield, performance

A spray polyurethane foam insulation said to be the first to eliminate ozone depletion and reduce the impact of global warming has been enhanced by Houston-based Lapolla Industries Inc. as company officials work to gain its acceptance around the world.

Lapolla uses Solstice, a liquid blowing agent developed by Honeywell International Inc., to make the closed-cell insulation product called Foam-Lok, which is low in hydrofluorocarbons (HFCs).

HFCs are potent greenhouse gases (GHGs) that contribute to climate change. Lapolla and Honeywell were private sector partners of a federal effort to limit GHGs. The blowing agent also is non-flammable and contributes to the foam’s insulating properties, which improves a building’s energy efficiency.
