When choosing windows it is important to understand their characteristics, pros and cons to decide which is best for your home. uPVC windows have become a popular window choice known for their sustainability and low maintenance features, made from uPVC (unplasticised polyvinyl chloride) which is a versatile building material. To help you decide if you want to install uPVC windows, our article will explain what uPVC windows are, how they are used, styles of uPVC windows, and pros and cons.
While PVC stands for polyvinyl chloride, uPVC is a type of plastic made from PVC with the chemical plasticisers removed. Hence the u in the name. The plasticisers are what makes the PVC flexible and soft. uPVC does not have chemical plasticisers but is made with tough modifiers and fillers that make it even stronger. It is an ideal material for window frames with a surface hardness equal to aluminium.
A uPVC window is a window frame made from unplasticised polyvinyl chloride (uPVC), a low-maintenance building material used as a substitute for painted wood, mostly for window frames and sills. It is often used when installing double glazing in new buildings, or to replace older single glazed windows.
uPVC has become a popular choice for windows for a plethora of reasons. It’s hard and weather resistant properties make it ideal for windows. We examine all the benefits of uPVC windows here:
uPVC windows are made through a process called extrusion which creates a material that is extremely hard and durable. They are then reinforced with steel inserts for strength and finished with fusion welded joints. This process results in a window that is strong, durable and heat resistant. The process of construction of uPVC windows involves four stages.
uPVC is the most versatile material for windows and boasts strength, durability and energy efficiency. However it is important to look at other window frame materials as a comparison to see which is best suited to your needs. uPVC, aluminium and timber are the most common materials used for window frames. Each has their advantages and disadvantages in areas like durability, longevity, energy efficiency and cost which we look at here.
uPVC and aluminium are two of the most popular material choices for window frames. Both are lightweight and robust. uPVC is made from a particular kind of PVC which is manufactured to become a lightweight but extremely strong and durable material. Aluminium, on the other hand, is also strong and durable. There are some major differences that make uPVC a better choice, however. uPVC is very affordable and often lower in price compared to aluminium. uPVC is highly energy efficient which will reduce heating and cooling bills, while aluminium does not have the same thermal insulation. In fact, aluminium windows have higher thermal conductivity which means they don’t provide the same level of insulation or noise reduction that uPVC frames can. Condensation is an issue with aluminium window frames because of the thermal conductivity issue and can lead to problematic mould development. While aluminium is a durable material, it can be susceptible to corrosion as the material is extremely vulnerable to saltwater and air.
Although timber is not as popular as uPVC or aluminium, it is still used for window frames when people are seeking a rustic or traditional aesthetic. Compared to uPVC, timber is far more expensive in terms of cost of materials and maintenance. Timber windows require regular maintenance including staining, painting and treating rot or weather damage. While uPVC is the most low maintenance of all the window materials, timber is susceptible to swelling or warping when exposed to the elements. uPVC is ideal for any climate whereas timber is less suitable for areas with extreme weather conditions like humidity or cold temperatures.
