2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Roofing sheets made from twinwall plastic are primarily 10mm thick, however, they are also available in greater thicknesses such a 16mm, 25mm and 35mm. Any thickness over 10mm would usually be called a Multiwall Plastic Sheet due to having multiple internal layers. Twinwall plastic can refer to several different extruded polymers including:

   Polycarbonate ( V d = 30–32 ) is very dispersive but has excellent shatter resistance. Trivex ( V d = 43 @ 1.53 ), is also heavily marketed as an impact-resistant alternative to Polycarbonate, for individuals who do not need polycarbonate's index. Trivex is also one of the lightest materials available.
