1 FI-FOIL® products are designed to be used alone or combined with other insulation as part of a system.

2 Semi-permeable versions of reflective insulation are highly recommended in hot-humid climates.

3 R-values vary based on amount of enclosed air space, air films, and R-value of other insulation used in combination and the direction of heat flow; contact us for an engineered solution.
