Why ONE STEP® Spray Foam Insulation?
Insulation in integrated modular units (IMUs) is essential for ensuring energy efficiency, reliable cooling, fire safety, and long-term performance.
Staycell ONE STEP® 502 HFO is the logical choice to insulate the underside of the structural, steel floor assembly due to its high R-value, fully adhered, seamless, fluid application that conforms to all shapes and configurations, providing unlimited design flexibility.
It’s quick and easy to install and eliminates the need to install ½" gypsum board underneath the floor prior to spray application as well as an intumescent paint over the exposed surface after installation.
