When it comes to maintaining and improving the energy efficiency of your home, uPVC windows are a popular choice. However, over time, the double-glazed and triple-glazed glass units in these windows may begin to fail, compromising their effectiveness. The choice then is between replacing the full window or just the glass panes.
In this guide, we will explore the pros and cons of both options, helping you make an informed decision that suits your needs and budget.
Is Replacing Only the Glass a Viable Option?
In many cases, yes, replacing the glass units in your existing uPVC window frames is a viable and cost-effective solution.
This process involves removing the double-glazed unit and replacing it with a new one that matches the same dimensions. The benefits of replacing just the glass include:
Quick and stress-free solution
Replacing the glass units in uPVC windows is a relatively quick and straightforward process that involves dry glazing. With the use of a rubber hammer and plastic shovels, the glass unit can be easily removed and replaced.
It is important to ensure the correct placement of plastic pads around the glass, as this contributes to the functionality of the opening windows. On average, it takes approximately 20 minutes to change a glass unit, allowing you to enjoy a crystal-clear view in no time.
Cost savings
One of the major advantages of replacing just the glass units is the cost savings. It is typically 65% less expensive than replacing the entire window, as you are only paying for the glass and not the frame.
Improved thermal efficiency
By opting for new glass units, you have the opportunity to upgrade the thermal efficiency of your windows. You can choose glass units with upgraded thermal coatings, tints, and even self-cleaning properties, enhancing the energy efficiency of your home.
Minimal disruption and mess
Since the window frames remain in place during the glass replacement process, there is minimal disruption and mess in your home. You won’t need to redecorate or worry about extensive dust and debris.
Retain the original window style
Replacing just the glass units allows you to retain the original style and appearance of your uPVC windows. This is particularly beneficial if you have unique or customized window designs that you wish to preserve.
uPVC Window Glass Replacement ‘DIY-Friendliness’
While replacing the glass units in uPVC windows can be a DIY project for some homeowners, it is important to consider your skills and expertise before embarking on the task. Here are a few factors to consider:
Skill level and experience
Replacing glass units in uPVC windows requires a certain level of skill and precision. It is essential to accurately measure the dimensions, remove the old glass units, and install the new ones properly. Additionally, it is crucial to pay attention to the correct installation of the inside/outside glass, as they often have special surfaces. If you possess confidence in your DIY abilities and have prior experience with similar projects, you may be able to successfully handle the replacement yourself.
Safety precautions
Working with glass can be hazardous, so it is crucial to prioritize safety. Ensure you have the necessary safety equipment, such as gloves and goggles, to protect yourself from potential injuries. If you are not comfortable or experienced in handling glass, it is advisable to seek professional help.
Tools and equipment
When replacing glass units in uPVC windows, specific tools and equipment like putty knives and glazier’s points are required. Unlike traditional windows, uPVC windows have gaskets and seals, eliminating the need for caulk during glass replacement.
This makes the process cleaner and more straightforward. Before starting the replacement, ensure you have all the necessary tools at hand.
Warranty and guarantees
If you choose to replace the glass units yourself, be aware that any warranties or guarantees associated with the windows may be voided. It is essential to check the terms and conditions of your warranty before proceeding.
Is it worth replacing uPVC windows?
Deciding whether to replace uPVC windows entirely or just the glass units depends on various factors.
Here are some considerations to help you make an informed decision:
Age and condition of the frames
If your uPVC window frames are relatively new and in good condition, replacing just the glass units can be a cost-effective solution. However, if the frames are old, worn, or lacking in thermal performance, it may be worth considering a complete window replacement to maximize energy efficiency.
Energy efficiency goals
If your main objective is to improve the energy efficiency of your home, replacing the entire window may provide better results. New uPVC windows often come with advanced features such as multi-chambered frames, low-emissivity glass, and improved seals, offering superior insulation and reducing heat loss.
Aesthetics and design preferences
If you are satisfied with the appearance and design of your current uPVC windows, replacing just the glass units allows you to maintain the same aesthetic while enhancing performance. However, if you desire a different style or want to upgrade to larger or smaller windows, a complete window replacement may be more suitable.
Budget considerations
Replacing just the glass units is generally more cost-effective than replacing the entire window. If budget is a significant factor for you, opting for glass replacement can help save money while still improving energy efficiency.
How long do uPVC windows last for?
The lifespan of uPVC windows can vary depending on various factors, including the quality of the materials, installation, and maintenance. On average, uPVC windows can last between 20 and 35 years or even longer. However, the double-glazed and triple-glazed units within the windows may eventually fail, leading to reduced energy efficiency and the need for replacement.
