Tyvek® Solar™ W20 provides all the benefits of Tyvek® Solar™ W10 but with the addition of a special performance-enhancing inner layer. The combination of a high reflectivity outer surface with a low-emissivity coating on the inside, makes Tyvek® Solar™ W20 the standard to beat when it comes to thermal radiation control. Normally the metal reflective layer on
a cargo cover is an impermeable layer allowing no inside-outside air exchange. However the metallized coating process for Tyvek® Solar™ W20 has been specially developed to permit the breathability of the cover to be maintained while its inward facing orientation reduces radiation in the direction of the cargo.
