Plastic has greatly changed the world when it has been introduced as a material for making things. Now you can find a lot of useful objects made out of plastic and they truly come handy for a lot of situations. One industry that has greatly benefited from plastics is the roofing industry with the great value that plastic roofing can provide in terms of function and style.

Light Weight and Low Cost

The use of plastic in roofing has greatly increased over the last few decades because of obvious and considerable benefits when compared to other types of roofing materials such as metal, wood, slate, ceramic, and asphalt. What people like about plastic roofing is their light weight, low cost, durability and ease of installation. Plastic roofs also come in different colors and thus are very much attractive especially for structures that have color motifs.

Ultraviolet Stabilizers

The main disadvantage of plastic roofing is their possible sensitivity to light and heat. Plastic can melt or fade with much exposure to the sun and changing weather, but this problem can be addressed with the thermal and ultraviolet stabilizers that have been added to newer productions of plastic roofs. extreme weather conditions may take a toll on the usual plastic roofs but with the right mix of chemical components some of plastic roofing material's problems can be minimized.

Plastic Roofing is usually made of polycarbonate, a standard thermoplastic material that is known for its excellent optical, thermal and mechanical features. The roof often comes in polycarbonate panels, sheets or tiles. What is good about the polycarbonate material is its good resistance to stress. It can withstand impact 200 times greater than glass, meaning that it would not be susceptible to damage when stones or hail fall on the roof. The mechanical properties of this type of roofing are also rather resistant to changes in temperature.

To reinforce the advantages of plastic roofing one can add ultraviolet radiation filters during the co-extrusion process of the sheet or the panel. Special additives may be used to prevent excessive interior heating. Cavity structures may also help increase the load capacity and flexibility of plastic roofing.

Lifetime Guarantee

Plastic roofing comes in varying prices and quality depending on the size, composition, thickness, colors, and profiles. The most common plastic roofing profile that people see is the corrugated one, as it has general better structural properties than flat ones. The cheaper plastic roofs are made of PVC while the more expensive and sturdier ones are made of polycarbonate components. The best quality plastic roofs may come with lifetime guarantees.

Installation of plastic roofing is quite easy, which is why it is usually the roofing choice for projects that have limited time frames. For optimal installation ease, manufacturers often recommend installing plastic roofing on a roof with at least 10 degrees of pitching. Anything lesser than that may require extra weatherproofing measures such as adding flashings or sealants.

Cutting the plastic roof panels for resizing should be easily done with a fine toothed saw or a pair of garden scissors. The better the quality of the plastic roof material, the easier it is to cut. Some installers use disk grinders with carborundum blades for more precisions when cutting plastic roofs, although one sheet at a time may be cut to avoid fusion and welding together.

Installation Tips

A good tip for installation is pre-drilling holes on to sheets before they are installed. Holes usually should be from 8mm to 10mm with some 2mm allowance based on the screw shafts to allow contraction and expansion. Holes should be drilled on the higher part of the roof's corrugation. It is usually easier to do the drilling with the sheet on the ground, upside down. A stick with a hole may also be used as a guide for drilling

Screws are used to secure the sheets of plastic roofing. Special screws are made for this purpose and may easily be bought from plastic roof suppliers. The easiest screws to use are those with hexagonal heads. Majority of the sheets or panels should be secured with four corrugation spaces and at every second when there are overlaps, ridging, and gutters.

Plastic roofing is definitely a staple choice in structural coverage. With its great function, light weight, and ease of installation, it is deemed to remain a popular choice of roofing in the appropriate situations.

Imagine paying for things with your cell phone. The Wireless Wallet is an idea that is picking up steam again, after the initial hype during the dot.com bubble fizzled along with everyones stock portfolio. As usual, Asia and europe are ahead of the united States in the introduction and use of new technologies using wireless data networks. In places other than the US, consumers are buying soda pop, paying for songs on jukeboxes, purchasing their groceries, and going to soccer games just by waving their cell phones at a machine!

In Sweden and the British Isles, drivers are sending text messages to the parking meter to pay for their parking, instead of stuffing it with coins. Think of the savings of time and trouble of not having to race the meter maid out to your car, to plunk in more change, you could simply send a message from across town! The Japanese are probably the most advanced at this technology, right now. They are using phones with embedded debit card chips that allow them to shop at restaurants and grocery stores and pay with their phones. The service is available in around 20,000 stores.

US companies often look to DoCoMo Company in Japan for inspiration and innovation, and they are watching the Japanese begin to use the phone as a replacement for train tickets. All of our wireless providers and phone manufacturers are currently involved in projects bringing this technology to our shores. Last year in Dallas, Texas, motorola and Mastercard had a trial run of a few hundred consumers using the wave and pay system at stores and gas stations. The technology is called near field communications and works when the device is about 8 inches from the sensor, similar to the check out scanner in supermarkets.

wireless companies are convinced the wireless wallet is worth developing because consumers in the US spent over 220 million dollars on Ringtones in 2004. J. P. Morgan Chase is testing the similar idea of cards that can be swiped to pay for things. They are involved with McDonalds and the 7-Eleven convenience store chain at implementing this in over 5000 stores. The idea is to then embed the contactless cards into phones. Some are still not convinced that this is a tenable idea, but Major League Baseball is intrigued by the technology, because they see it as an efficient way to get large numbers of fans into the baseball parks in a short amount of time. I can just imagine a promotion where your phone is singing the tune: Take me out to the ball game

As ubiquitous computing emerges, I think we will see our phones become TVs, music players, organizers, video arcades, Internet surfing devices, and more. And yes, it looks like they are well on their way to becoming wallets. The next time someone asks you for spare change, you can say, sorry, I left my phone at home!
