Why Choose uPVC For Doors and Windows?

uPVC (unplasticized polyvinyl chloride) also called rigid PVC has gained quite notable popularity in the construction industry. Its trending demand can be linked to the sustainability and durability of the material. Due to the absence of plastic (unplasticized), uPVC has properties such as rigidity, robustness, and higher insulation.

Rather than going for aluminum or wood, consumers are preferring uPVC doors and windows. But why is that? What is so special about uPVC that has made mahogany wood and expensive aluminum fail? Here's why:

Easy to Maintain

The uPVC door and window frames can be easily cleaned using a homemade cleaner, made out of liquid soap. Their smooth surfaces are easy to clean, and the granules are weather resistant.

Energy Efficient

The uPVC windows are much better insulated than the regular glass. This means they are much more effective in cutting out heat and maintaining cool temperatures within a premise.

Weather Resistant

Unlike wood that is prone to warping in the rainy season, uPVC doors and windows are weatherproof and stay unaffected by the different climates of the places.

Environment-Friendly

These are entirely recyclable, 100% lead-free, which protects several resources in return. Out of the 40% of all the resources are used for the purpose of building, only 1% is used by uPVC.

Top Technologies for Glass Processing

The new glass processing technologies open a new mode for heat processing glass that results in a significant reduction in capital and operating costs, as well as increased product quality and the possibility of new types of glass products. Below are some examples of these technologies.

 1. Melting glass-making ceramics and glass waste

Glass and glass-making ceramics can be rapidly melted directly by the gyrotron beam with a heating rate of over 1,000 degrees C (2,0000F) per second. As a result, many of the current difficulties in melting glass and re-melting glass waste can be overcome, providing a highly efficient and shorter melting process and opening the way for smaller glass melting tanks.

2. Processing coatings on glass

The new glass processing technologies have been used for making and processing different coatings on glass surfaces. One of these processes is pre-firing frit. Frit material has a significantly higher absorption of microwave energy than glass. Therefore, when the beam is applied directly, the frit easily reaches the needed temperature for pre-firing, while glass stays cooler without impacting its shape or flatness.

3. Glass Cutting

The new glass processing technologies have been used for effective, high-quality glass cutting due to the gyrotron beam’s ability to be focused precisely on a glass surface, as well as heating the glass quickly and uniformly throughout its thickness. When the beam comes into contact with the glass product (sheet or tube) and heats it locally, it produces internal residual tensile stress, due to the formation of a temperature gradient. When the beam moves along the desired cutting line and its power is high enough to create stress higher than the glass breaking point, a crack occurs through the entire glass thickness and travels with the gyrotron beam, resulting in glass separation along the desired line.

4. Joining glass (VIG)

Another example of the new glass processing technologies is the ability to heat materials selectively in the sealing process for the production of vacuum insulated glass (VIG). The microwave energy of the gyrotron beam is directed locally and solely on the perimeter area and heat/melt frit exclusively, leaving the glass relatively cold and thus maintaining temper strength. The level of temper strength after gyrotron beam processing remains high (above 80% even in the processing area) because processing is rapid and local. Outside the processing area, the glass remains practically at its original tempered level.
