uPVC windows and doors are more cost-effective than Aluminium windows and doors. But just because uPVC is a less expensive material doesn't mean it is an inferior choice. Your budget and style preferences will have a lot to do with the material you choose. Aluminium windows are more robust and offer greater flexibility for larger more structural designs. It's worth budgeting carefully if this is the look you desire. One way to manage cost is to consider mixing uPVC and Aluminium windows and doors in your home.
If you are extending your home, purchasing new windows for the entire house can be costly. Mixing uPVC and aluminium windows is something that people do to achieve the look you want without blowing their budget. uPVC windows are often a good option when replacing the existing windows in a home.
