What are the BakFlip panels made from?
BakFlip panels are actually sandwich panels. Although they are relatively light in weight, they are extremely strong. The exterior is either an impact resistant fiberglass polymer or aircraft grade aluminum. The inner core of the BakFlip is a super dense, EPS (polystyrene). This allows the BakFlip panels to be insulated and impact resistant. Most importantly the panels are completely watertight.
