Gaco FireStop™ Open Cell Spray Foam

Gaco FireStop™ is unlike any other open cell spray foam insulation, because it requires no additional ignition barrier, an often lengthy—and spotty—second application step. Thanks to BioMax technology, it’s built into the formula. A proprietary formula that of course, also includes Gaco’s Air Seal Advantage: a single, solid polyurethane barrier with energy savings up to 40%. So it’s strong, formulated to last for decades. It’s seamless, so it’s high performance. And it’s one step installation to save time and money.
