TopGal is the latest multiwall polycarbonate system to be developed by Polygal. These sheets come with an upgraded four wall structure that offers more rigidity, thermal insulation, strength, and lower solar heat gain than the standard 8mm Polygal sheets. The standing seam style system simplifies the installation process, leaving less room for mistakes. No screws are installed through the sheets, and it is impossible to install the sheets upside down.
