Polycarbonate roofing panels are made from a type of thermoplastic polymer. The panel is a translucent plastic which comes in various sizes and thickness. Polycarbonate sheets are most commonly used in making greenhouses. It is often used in automobiles as it is light weight and has high flexibility. It has several other benefits such as low installation and maintenance costs, and easy installation.
Polycarbonate sheets are cheaper and lighter than materials such as glass. Installation is easy and less time consuming because of their light weight. As a result. the labour costs are reduced during the faster installation timeframe. Lighter roofing needs a lighter framing than glass roofing; such as wood, aluminum or steel. Again this reduces the costs of materials and installation.
Polycarbonate sheets are much more flexible than wood, glass or metal. This means it can be molded into several shapes such as a dome or even an igloo. The flexibility allows creative designing to take place.
Allows For Great Transmission Of Light
Polycarbonate roofing sheets transmit more light in comparison with other materials used in a greenhouse, such as polyethylene film. A 6-mm double wall panel transmits about 85% of all available light. Compare this with a polyethylene film, the polycarbonate roofing has more direct radiation.
Higher Impact Resistance
Polycarbonate roofing has a high impact resistance and therefore a lower flammability rate. As a result it is less likely to break in areas prone to golf balls, hailstones, heavy snow fall, animals and birds. Along with this chances of breakage during assembly and transportation are low. In a rare episode of breakage, polycarbonate fragments are not as dangerous as glass shards.
Polycarbonate sheets come with a lifetime expectancy of about 10 to 15 years. Most manufacturers have a guarantee of at least 10 years.
No Warping Or Fading
Unlike PVC roofing, polycarbonate sheets do not deform or fade easily. It has a much higher softening temperature. Polycarbonate roofing panels come in several colors that do not fade due to weather impact. Therefore, polycarbonate sheet roofing is good for both cold and hot weather
Double paneled polycarbonate roofing provides extra insulation. Polycarbonate roofing is either single or multi-layer. The number of walls separated by air is determined by the use of the roofing. Greenhouses use a single layer, while homes and offices usually use multilayers. The air between the layers of sheeting reduces heat loss and provides insulation. The reflective properties in polycarbonate sheets keep harmful UV rays out. This reduces costs such as electricity bills and allows sunlight into the building.
