Staycell ONE STEP® 255 Intumescent Spray Foam Insulation - Preferred Solutions, Inc. (PSI)

Staycell ONE STEP® 255 is a two-part, closed-cell, intumescent, spray polyurethane foam product used to insulate roof decks, ceilings, walls, siding or structural steel and to provide an integral air barrier / insulation / vapor retarder for building envelope assemblies.

What makes it unique?

Staycell ONE STEP® 255 offers superior fire-resistance and qualifies as an Alternative Thermal Barrier Assembly when installed exposed without thermal barriers, ignition barriers or other fire protective surfaces - a first for the spray foam industry. Staycell ONE STEP’s patented intumescent technology makes the foam fire-resistant – the fire resistance is built right into the foam itself. It’s less expensive to install because it does not require the addition of fire barrier coatings.
