Thinking about PVC windows

Windows choices are a big decision to make when you build a new house, or even when you would like to change the old ones. A lot of people love the wood windows and brands like Andersen, Marvin and Pella are among the most popular for the majority of the customers that can spend a little bit more to have great windows. But sometimes even the most expensive windows series from these brands have problems (some prefab colors, for example, does not exist in some series). In the recent year PVC and UPVC windows are representing one of the most afordable options for replacement windows, for example.

PVC (polyvinyl chloride) is a synthetic plastic polymer, which is created by chemical reactions. Vinyl is usually made in rigid and flexible forms. In order for it to become flexible, plasticizers are added to the compound. Plasticizers are commonly solvents that has a goal to turn the material a little bit more flexible.

The “U” in UPVC stands for “unplasticized”. An interesting facy is that although they are commonly referred to as PVC windows, most vinyl windows are in fact made from UPVC. UPVC is not as flexible, is more weather and fire resistant, doesn’t deteriorate, warp, or discolour as fast as regular PVC and can be a good option for your windows. It is also not as toxic or dangerous to the environment as plasticized vinyl.

Window frames made of PVC score top marks when compared with aluminium or wooden windows. They have better insulation values and are able to reduce energy and heating costs. Vinyl sashes also offer better performance and energy efficiency from your insulated sealed units. These windows can also accommodate grilles inside the sealed unit.

Think about that in your next window replacement. It can save you money and help the environment.
