When looking into installing uPVC windows, one of the first things to consider is price. uPVC is the material used for a window frame and is usually combined with double glazing. It is much better for the environment than PVC and an affordable alternative to wood and aluminium. In this article we will explain what uPVC is, how it is used with double glazing, and how much uPVC windows cost to help decide if it is right for you.
What is uPVC?
uPVC stands for unplasticised polyvinyl chloride, and can be used in window frames when installing double glazed windows. Unlike traditional PVC (polyvinyl chloride), uPVC is an unplasticised polymer which makes it more rigid and durable, ideal for construction uses like window frames. Put simply, uPVC is the same as PVC but without the plasticisers. The plasticisers give the PVC their flexible and soft quality, so minus this element, uPVC is a much stronger and inflexible material.
Benefits of uPVC
uPVC is fast becoming one of the most popular choices for window frames particularly when combined with double glazing. Specifically designed as a high quality and durable material, uPVC is ideal for the construction industry. Here are the main benefits of uPVC.
- Durability and strength: uPVC is made to be a strong material with a high level of impact resistance. uPVC windows are manufactured to be durable and strong enough to handle everyday wear and tear. Often uPVC window frames are made with steel reinforcements which make them even stronger and more durable.
- Weather resistant: uPVC is weather resistant, unlike its aluminium or timber counterparts. Wood can rot over time and aluminium can warp in extreme heat but uPVC can be exposed to all weather conditions and the elements without losing any shape or strength.
- Low maintenance: Because uPVC is not susceptible to the elements, rotting or corrosion over time, it is extremely low maintenance. It will not need to be painted, or have mould or rust removed. Perhaps the occasional clean down with a soapy sponge is the most maintenance needed.
- Energy efficient: Combining uPVC frames with double glazed windows can dramatically improve the energy efficiency of a home. The conductivity of the unplasticised polyvinyl chloride is low which means reduced heat transfer from the interior to exterior and vice versa. The insulation properties of uPVC result in less energy needed to heat or cool a home and reduced energy bills.
- Longevity: uPVC is built to last a long time. Most uPVC windows will last for 30 years or more.
- Low cost: uPVC is the least expensive material for window frames. It costs less to produce and so is more affordable for window specialists to purchase.
- Customisation: uPVC window frames can be customised to suit the design and style of a home. It is not a one size fits all window. They are available in a range of colours and finishes to create a unique look to a home.
- High security: Breaking wood or bending aluminium helps people get in through your windows. uPVC is strong and durable and won’t break easily.
- Fire resistant: uPVC is flame resistant material and will not catch fire or spread flames. The inherent chlorine content inside uPVC acts as a natural flame retardant.
- Recyclable: uPVC can be recycled for window frames up to 7 times before it has to be used indoors or recycled for a different purpose.
How Much Do uPVC Windows Cost?
In a new home, uPVC with double glazing will cost $1500 to $3500 plus per window. This includes supply, delivery and new build install.
For existing homes, a uPVC window with double glazing will cost about $2,500 to $4,500 plus. This would include supply, delivery, installing the frames and glazing, and disposal of the removed windows. This is only an estimate and the final cost will depend on a number of varying factors like window size and the number of windows installed.
Cost Compared to Other Window Materials
As we have explained, uPVC material is more cost effective than most other materials, particularly timber frames. Aluminium can be slightly less expensive but is usually a similar price or slightly more. These are the costs of other double glazed window types for the average sized window.
- Aluminium windows: An approximate cost for aluminium double glazed windows of a similar size is $2000-$5000. Aluminium is not as energy efficient as uPVC. The aluminium material conducts unwanted heat through the frame in hot weather.
- Timber window frames: The most expensive of all the frame materials, timber double glazed windows will cost between $3000-$6000. Timber is high maintenance and requires regular painting although it is similar in performance to uPVC for energy efficiency.
Factors Affecting uPVC Window Cost
The cost of uPVC windows may fluctuate based on a number of factors. Everything from the type and size of window to how accessible a property is can impact the price. We examine each element that influences uPVC window price here.
- Type of window design: The type of window design affects the uPVC window cost. Some window designs are far more complex than others, which will raise the price. A more intricately designed frame like a bay window will be more expensive than a straightforward design of a fixed window. Similarly, bifold windows are a more technical design requiring more skilled installation than a simple picture window.
- Window hardware: Hardware on a window is things like locks, hinges, handles and openers. Intricate hardware and high security features will add to the cost of the uPVC window frame.
- Size of window: The larger the uPVC window, the more expensive it will be. That is because more materials are needed to make a bigger window. Structural reinforcement will also be needed to install oversized windows safely.
- The number of windows: Obviously the more windows you install, the more expensive it will be. However, there is a benefit of installing windows all at once as often you can get a better price for uPVC windows in bulk.
- Property issues and installation: If a property is difficult to access and windows are hard to install, it will raise the cost of the uPVC window. Often the window project will then include more skilled labour, specific mounting requirements, and longer installation times.
- Type of glazing: The type of glazing you have installed in your uPVC window frames does impact the overall cost. Double glazing costs about 40% more than single glazing but the combination means long term benefits of consistent savings on energy bills.
Quality vs Cost
When building or renovating a home, it is important to consider quality vs cost during the construction process. While the cost of uPVC double glazed windows is an affordable option compared to other window materials, there is still an initial investment. It is important to work out if the quality and benefits will compensate for the extra cost. Double glazed uPVC windows do have a higher upfront cost but the high quality material means they will pay for themselves in reduced energy bills and environmental impact.
When looking at the cost of uPVC windows, it is important to take into account a variety of factors to determine if they are the right choice for you. In this article, we have explained what uPVC windows are, how they can save you money, and how double glazing is the perfect solution for optimal energy efficiency.
