Seattle, Washington - Gaco Western's FireStop open cell polyurethane foam has passed an industry flammability test for the second time, the US foam company said in a 6 July announcement.
Gaco said its FireStop product passed the US AC 377 Appendix test for flammability, exceeding the minimum time of 4 minutes and 18 seconds without a coating. This second test was with the "skin on" meaning that it passed without any major trimming.
The foam in the first test, carried out in February of this year, had been shaved. Gaco said the results of these tests showed that FireStop can be used with or without trimming, and in both cases without any additional coating.
"The results of the second test mean that customers have double the safety," said Peter Davis, ceo of Gaco Western. "Now code officials and all of our customers - builders, contractors, and homeowners - can be doubly certain that GacoFireStop meets and exceeds all relevant fire codes because we passed twice."
As a result of the recent test, Gaco Western said it will be launching a campaign to educate fire and code officials about FireStop and the characteristics that allow it to pass rigorous testing.
