A disposable, pressurized kit containing two chemical components that mix in a nozzle to create expanding polyurethane foam. Crews use these kits for air sealing, filling small voids, or patching insulation where bringing in a large spray-foam rig is not cost-effective.
Heard on the job
Grab a froth pack from the truck and seal up those rim joists before the drywallers get here.
Insider tip
The chemicals are temperature-sensitive; if the tanks are too cold, the foam will not expand properly and will cure with a dense, brittle texture.
