UPVC Is one of the development products of PVC Kusen. PVC frames are usually used only as indoor materials because PVC is less strong and breakable easily. But different with uPVC. The material which is a sole of Unplasticized Poly Vynil Chloride is a plastic derivative material, whose plastic properties are minimized so that its shape becomes hard (decreases its flexibility). The inside of the uPVC frame is framed so that the frame is sturdier and heavy. The frame is made of steel, but some are of galvanized iron. This frame difference causes uPVC prices to vary. UPVC is a steel profile certainly more expensive when compared with using galvanized iron. The best window material materials you can get from austin window treatments.
In terms of the difficult strength of comparing the Aluminum Frame and the uPVC Frame. Because of each anti bugs resistant to water and weather, and minimal maintenance. Although made of metal, Aluminum frames are good quality resistant to corrosion. Likewise uPVC because it is made of plastic derivatives it is clearly corrosion free. It is quite difficult to compare between the Aluminum frame and uPVC frame. Note, however, that Aluminum corner joints mostly use only screws so they are easy to loose and expand. As a result, the glass held by the frame is easily released. Although not uncommon from this connection water can seep in. Meanwhile, uPVC is directly connected to the factory using a firing/heating technique so that it is stronger and more leak-proof. A frame made of uPVC plastic coated with a retardant material that can slow the rate of fire.
How about price? Compared to uPVC, aluminum is cheaper, but it can not be shaped into a variety of shapes due to its rigidity. Unlike uPVC that can be made even curved circular. Therefore the best solution to use uPVC frames because uPVC frames have advantages and are a treand world at this time.
