About 4mm Polycarbonate Sheet
Polycarbonate sheets are lightweight making them easy to handle, low maintenance, and may be easily cut and installed in different locations. Moreover, a transparent 4 mm polycarbonate sheet has the additional advantage of letting natural lighting through. The thickness of this type of 4 mm polycarbonate sheet fits the requirements of roofs and greenhouses, which need strength and resistance in addition to transparency. Moreover, a 10 mm clear polycarbonate sheet could be a better fit for some constructions, but 4 mm greenhouse polycarbonate sheets are usually good enough for most uses. Some eBay top sellers are not only offering quality polycarbonate sheets of different sizes and thicknesses, transparent or coloured, but also free shipping.
