Aluminum Sandwich Panel, Comes in Various Sizes, With Polyurethane Foam Core
Polyurethane sandwich panels are made of upper & lower steel sheets injected in between with polyurethane foam, with varying thickness.
They offer a high insulation factor with complete water and vapor leakage protection.
Their light weight and high load bearing allows for longer spans.
