uPVC is an inexpensive plastic that offers excellent insulation and requires relatively little care and attention. Wooden window frames are a popular choice among those looking to invest in the outward appearance of their home. Aesthetically, wooden windows offer more than uPVC windows and since every piece of wood is different, each wooden window is unique. One of the key differences between wood and uPVC windows is the price, uPVC windows cost far less than timber ones making them a popular option. Timber windows require more maintenance than uPVC in order to function at their best, uPVC requires very little attention. Combined with Double Glazing, both uPVC and timber windows offer excellent insulation keeping the hot air in and the cold air out. This is good for homeowners as it helps to reduce heating bills.
