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.
Gaco FireStop™ 5500 is a water blown spray-applied system that cures to a semi-rigid low density foam. In-place density is approximately .55 lb/ft3. The cured product is dimensionally stable in all weather conditions and its insulating properties do not significantly diminish over time. GacoFir eStop 5500 is safe for the environment, containing no CFC’s, HCFC’s, formaldehyde or ozone depleting chemicals. GacoFireStop 5500 is a Class 1 fire rated foam. GacoFireStop 5500 meets the requirements of AC377 Appendix X for use in attic and crawl spaces.« back to products
