  • Polyvinyl chloride, or PVC, is a lightweight and extremely strong plastic used in different areas of construction. The addition of plasticizer chemicals make it more flexible and malleable. If no plasticizers are incorporated it is known as uPVC, or unplasticized polyvinyl chloride. uPVC is also called vinyl siding or rigid PVC. It was first used in windows in 1940, and is now used worldwide. There are many pros and a few cons to using uPVC windows.


The pros of using double glazed uPvc windows far outweigh the cons. The biggest benefit comes in the form of financial savings. They are great for any size budget and will save the homeowner a lot of money in the long run. Other pros include:

  • lower electric bills due to the windows insulation ability
  • keep heat inside during the winter, and heat outside during the summer
  • uPVC windows require virtually no maintenance
  • scratches and scuff marks don’t show
  • a long life span
  • uPVC doesn’t rust and is not susceptible to termite infestations
  • extremely easy to clean
  • uPVC has approximately 57% salt content making it perfect for people with homes built along the coast
  • fusion welding on the frames, instead of nails, prevents drafts and water leaks
  • outside noise levels are significantly reduced


As mentioned earlier, there are a lot more advantages than disadvantages when it comes to uPVC windows. At Sebastian Church Builders we try to give both sides of the story so every customer knows exactly what they are buying. Some of the cons include:

  • uPVC windows are not suitable for high rise buildings or skyscrapers, though this will not affect the vast majority of our clients
