If your home still has single glazed windows or even double glazed windows that have seen better days and have leaky seals then you will no doubt be looking to get these replaced at some point, you may have even seen neighbours and friends getting the newer UPVC windows fitted and been envious of how good they look as well as not requiring constant maintenance and upkeep like older wooden frame do.
These new windows may look expensive but in reality the cost of these windows is much less as the materials used are incredibly cheap to produce compared to the extensive sourcing involved in wooden and timber frames. This cheaper material doesn't make any compromises on the quality and build strength of these windows either, UPVC has been proven to be a more resilient and weatherproof material as well as being able to provide greater security as the construction of the window frames is toughened by the internal pockets of air and channels helping to increase rigidity.
Seals on UPVC windows are also less likely to leak over time, this is mainly due to how the material does not swell or change in size under changing weather conditions like wood does. So UPVC is not only cheaper but stronger as well, how else can they help to reduce our costs? Well double glazed windows are able to trap warm air between two panes of glass which act as an insulator against the cold air outside. If you didn't have this then the cold air outside would chill the glass and have the same effect on the air inside your home.
How does this affect what you will pay though? Well with double glazing this layer of insulation means the warm air generated from the central heating or fire in your home will not escape and so will not be needed as much.
