In this video, we take a close look at aluminum foil faced polyurethane insulation panels and explain how their reflective foil surface and closed-cell core work together to reduce heat gain and heat loss. You'll see how the panels are installed with butted, staggered joints and sealed foil overlaps, and learn where this vapor-tight, moisture-proof insulation is best used across roofs, walls, ducts, cold rooms, and industrial envelopes.
