Considering adding a conservatory to your property? One of the choices you have to make is which material to use – glass or polycarbonate roofing. If you are still undecided on this matter, here are a few reasons why you should opt for the latter. Cost: Although there are several homeowners who will choose glass over polycarbonate sheet roofs, some homeowners working with a limited budget cannot make such an immediate decision. If you are looking for a cheaper alternative to glass, your best option would be polycarbonate roofs. Apart from their low cost, polycarbonate roofs are lighter in weight which makes them easier to install and will require less installation time as compared to glass. Over the long term, you can save more money as labour costs go down. On top of that, the light weight of polycarbonate roofs means that they can be installed with lighter frames like aluminium, wood and steel. Again, this means that you can save more money. Flexibility: As compared to other building materials like glass, wood or metal, polycarbonate roofs are very flexible. This means that if the design of your conservatory or sunroom calls for unconventional shapes, polycarbonate roofs can be moulded to the desired shape. Light transmission: Polycarbonate roofs are perfect for greenhouses because they can let in a great amount of light. Compared to polyethylene film, a popular material used for greenhouses, polycarbonate roofs can let in as much as 85 percent of available light. But despite this benefit, some polycarbonate roofs available in the market have been treated to effectively minimise the harmful effects of sunlight and UV rays. Impact resistance: Glass may look good in your sunroom, but there is one great caveat: its fragility. Polycarbonate roofs, on the other hand, can withstand a high amount of impact from animals and birds, wayward balls and other objects that can shatter glass. This property also makes polycarbonate roofs easier to assemble and transport. Durability: Polycarbonate roofs are also known for their unmatched durability, bearing a lifetime expectancy averaging about 20 years. During this period, you can expect your polycarbonate roof to withstand conditions that can warp or discolour similar roofing materials.
