• GREAT STUFF Fireblock Insulating Foam Sealant with Quick Stop Straw Technology can save much more than energy costs. By sealing the pipe, cable and duct penetrations, you minimize airflow. During a fire, that means flames, harmful gasses and toxic smoke cannot spread as quickly. And in an emergency, that could make all the difference. The fact that it helps you conserve energy, reduce drafts and save on heating and cooling costs is great too.
