Q. Which is best sheet for roofing?

Polycarbonate sheets are a popular roofing material with foam-backed and transparent varieties being the most common. Roof sheets made of foam-backed polycarbonate are both lightweight and sturdy. Due to their durability and sturdiness they are commonly seen in warehouses and other industrial settings. The increased airflow and impressive vaulted ceilings/attics are two additional benefits of these layouts.
