How Long Do UPVC Windows Last: A Guide To Replacement

Windows made of Unplasticized Polyvinyl Chloride are popular because of their low maintenance requirements. They are frequently used as a painted wood alternative, mostly in sills and window frames. They are installed for double glazing purposes in new construction, or to improve energy consumption by replacing older single glazed units. Continue reading this article to learn answers to the question ‘How long do uPVC windows last?’

The short answer to a question of lifespan for the windows is: ‘Approximately two decades’. However this figure can vary by as much as ten years in either direction. Some of the factors which affect the lifespan of a typical uPVC window include quality, quality of installation and window location. These factors are true of most building material components. Severe weather conditions and salt air in some locations, such as coastal property. Are hard on a window.

Although the polyvinyl products are very low maintenance, and a two decade lifespan is typical, the quality of the product and its installation may mean that it is time to replace units which were installed before the turn of this century. This is true, even if they were professionally installed.

When maintenance costs are wrapped into the total cost of the building material, uPVC measure up quite well. They do not need to be sanded, painted. Or resealed. They are not subject to moisture absorption or warping in the same way as wood units are. The loss of heat is measurably mitigated by double glazing and the use of the polyvinyl chloride material. Steps taken to reduce loss of energy through the glass or the sills and frames are a tactic which pays off in dollars and cents.

The window panes of a building are perhaps the greatest cause of heat loss and high energy costs. Certainly, if single pane units are replaced by those with double glazing, the homeowner or building owner will be more comfortable.
