Carlisle SealTite PRO R-3.7 Open Cell B Side Polyurethane Spray Foam Insulation 351817

For more comfortable and consistent indoor temperature control and optimum energy efficiency, SealTite PRO’s Open Cell spray foam products are the natural choice. Open Cell is a two-component, light-density, one-to-one-by-volume spray polyurethane foam. No Ignition Barrier Coating is required when used in assembly-specific attic applications. To produce Open Cell requires the use of a blended "B" component (Resin), which contains ZERO ozone-depleting blowing agents, catalysts, polyols, and fire-retarding materials. Open Cell is an insulation system designed for use in residential applications. Use it in lieu of more traditional forms of insulating materials such as fiberglass, cellulose, or other loose fill products. Typical areas where Open Cell is applied are exterior walls, vented attics, unvented attic assemblies, and between floors.
