Glass lets in a ton of light, looks good, lasts quite a while, is seldom broken by wind and can easily be mended, but it costs a great deal and requires a strong system to convey its weight. Fiber fortified plastic comes in huge sheets; it is easy to fit and does not require extensive surrounding. It also takes some of the heat out of a blistering sun, which is an awesome thing. However, it does not admit as a lot of light as glass and this is a serious disadvantage in winter. It is also inflammable, and will just last twenty years.
PVC and acrylic modified plastic are less expensive and transmit light well, but they will last just five years and can be torn by a storm. Polyethylene is exceptionally modest – about a tenth the cost of glass – and transmits light effectively. But it will just last a couple of years, and is easily torn by gales. Transparent plastics are turning out to be mainstream everywhere throughout the nation, and as long as plastics stay modest comparative with glass, they are well worth using. Glass is, of course, better in the long haul, but – it represents a substantial capital investment nowadays.
