Insulated Option Available: Insulation is available as an option for Expand-O-Flash® to provide a thermal barrier or noise reduction. The insulation option includes a high-quality polyethylene vapor barrier that both supports the insulation and prevents moisture from inside the structure from collecting on the insulation.

Other R-values are available upon request.
