Twinwall & Multiwall Polycarbonate Sheet

Twinwall / Multiwall Polycarbonate Sheet

Twinwall or multiwall polycarbonate features a cellular structure with two or more walls enclosed by connective ribbing. The multiple wall structure creates insulating air cells that help to make this polycarbonate grade more energy efficient when compared to using a single sheet of polycarbonate

It's often used in construction due to it being lightweight while still offering impact resistance, flexibility and UV protection making it suitable for indoor and outdoor applications.
