Honeywell Enovate® HFC 245fa blowing agent is a non-flammable, zero ozone-depleting liquid that allows closed-cell spray foam insulation to expand. It provides many of the foam’s key performance characteristics:
•Closed-cell spray foam using Honeywell’s Enovate foam blowing agent has R-values greater than 6 per inch, which result in heating and cooling cost savings. Drafts are virtually eliminated and a more constant indoor environment and temperature is maintained.
•Closed-cell spray foam offers superior performance in resisting moisture transmission and condensation. When sprayed at a 2” thickness, it provides a vapor retarder with a 1 perm rating.
•Wind uplift resistance can be increased up to three times when closed-cell spray foam is applied under a roof deck.
•Closed-cell spray foam helps prevent uncontrolled outdoor air infiltration and the penetration of dust, pollen and other allergens, creating a cleaner, more comfortable environment.
•Closed-cell spray foam can be used in both wood & metal framed structures, including walls, floors, ceilings, roof decks, attic floors, crawl spaces, basements and foundations.
