What is the cost difference between wooden window frames and UPVC windows?
UPVC windows are highly used and sought after for a few reasons with the main reason being that UPVC windows and doors are low cost but also help keep your energy bills low. The initial investment is smaller in comparison to wooden doors and frames but the maintenance is also quite cheap and simple. It is highly unlikely that you will need to replace UPVC frames in the short term, or ever really, whereas wooden windows require much more maintenance and eventual replacement. Especially in more humid and moist climates.
It is hard to give an exact price difference or cost of either option because the final cost will be determined by many different factors, such as window size, how many windows, if you want different types of locks or multi-directional windows for improved airflow. These are just a few factors that will affect the price no matter which you decide to go. It is best to consult with a UPVC windows or wooden windows specialist to understand the pricing, options, advantages, and disadvantages of ether choice.
