The fire-resistant polyurethane foam Sika Boom-420 Fire – 750 ml is a one-component expanding foam developed by Sika specifically designed for fire-stopping sealing of linear joints in buildings.
It offers fire resistance of up to 240 minutes (EI 240) depending on configurations in accordance with the EN 1366-4 standard. The Sika Boom-420 Fire thus restores the fire resistance performance of walls and floors crossed by passage joints or openings.
Thanks to its combi aerosol, this foam can be applied with the Sika polyurethane foam gun via the integrated adapter or manually using the supplied extrusion nozzle.
Ready to use, it is easy to implement and perfectly suited for quick interventions on site. After curing, the foam can be cut and sanded, facilitating finishing and integration into the structure.
