INSULATION MARKETPLACE Reflective Insulation Roll vs Armacell AP Self-Adhesive Sheet Insulation

These solve different problems. The INSULATION MARKETPLACE roll is a thin reflective radiant barrier for windows, garage doors and attics, while the Armacell AP sheet is a 1-inch closed-cell elastomeric foam for ducts, pipes and equipment. For blocking radiant heat and sunlight through glass or a garage door, the reflective roll is the better fit. For wrapping ductwork or metal surfaces that need real conductive insulation, the Armacell sheet wins. Owners of the reflective roll praise how easily it cuts and fits; Armacell's foam is the more durable, professional-grade material but is not a radiant barrier.

• Choose the INSULATION MARKETPLACE reflective roll if you want to cut radiant heat at windows, a garage door or an attic and need something thin, flexible and easy to cut to size.
• Choose the Armacell AP sheet if you are insulating ducts, pipes or equipment and need thick closed-cell foam with a self-adhesive backing.
