Why draughts are an issue in UPVC windows

Energy inefficiency

Draughts can significantly affect your home’s energy efficiency. When cold air enters your living space, your heating system needs to work harder to maintain a comfortable temperature. This increased workload can lead to higher energy consumption, which in turn results in increased energy bills.

Comfort Concerns

Draughts can make your home feel uncomfortably cold during winter months. They can also lead to uneven temperature distribution, with some rooms feeling colder than others. This can result in the need for additional heating sources, such as space heaters, further increasing energy consumption.

Noise pollution

Draughts can also allow external noise to enter your home more easily. This noise pollution can be disruptive and reduce the overall quality of your living environment.

Identifying the causes of draughts in UPVC windows

Damaged or worn seals

One common cause of draughts in UPVC windows is damaged or worn seals. Over time, the rubber seals that surround your window can degrade and lose their ability to create an airtight barrier. This can allow air to pass through, leading to draughts.

Incorrect installation

Another cause of draughts in UPVC windows is incorrect installation. If the window has not been fitted correctly, there may be gaps between the window frame and the wall, allowing air to enter your home.

Poor window design

In some cases, the design of the window itself may contribute to draughts. For example, if the window does not close tightly or if the frame is warped, air can easily pass through, creating draughts.

Solutions to stop draughts in UPVC windows

Replacing or repairing seals

Types of seals

To address draughts caused by damaged or worn seals, you can replace the existing seals with new ones. There are several types of seals available, including rubber gaskets, brush seals, and foam seals. It’s essential to choose the right type of seal for your specific window to ensure the best results.

How to replace seals

To replace the seals on your UPVC windows, you’ll first need to remove the old seal. Carefully pry it away from the window frame using a flathead screwdriver or a similar tool. Next, measure the length of the new seal, cut it to size, and press it firmly into the groove where the old seal was. Make sure the new seal is properly seated to create an airtight barrier.

Adjusting window hardware

Hinge adjustments

In some cases, draughts can be caused by misaligned window hardware. If the window is not closing tightly, you can adjust the hinges to improve the seal. Most UPVC window hinges have adjustment screws that can be tightened or loosened to change the position of the window sash. Make small adjustments and test the window to ensure a snug fit.

Lock adjustments

Similarly, adjusting the window lock can help eliminate draughts. If the lock is not engaging properly, the window may not be fully closed, allowing air to pass through. Check the lock mechanism and adjust it as necessary to ensure a tight seal when the window is closed.

Draft-proofing products

Weatherstripping

If you’re still experiencing draughts after addressing seals and hardware, you can consider using weatherstripping products. Weatherstripping is a material, often made of rubber or foam, that can be applied to the edges of your window to create a more effective seal. This can help reduce draughts and improve energy efficiency.

Window film

Another option is to apply window film to your UPVC windows. Window film is a thin, transparent material that adheres to the surface of the glass. It can help reduce draughts by creating an additional barrier against air infiltration.

When to seek professional help

If you’ve tried the above solutions and are still experiencing draughts, it may be time to consult a professional. A window specialist can assess your UPVC windows and recommend the best course of action, whether that’s repairing the existing windows or replacing them with new, more energy-efficient models.

Preventative measures for future draughts

To prevent draughts from reoccurring in the future, it’s essential to maintain your UPVC windows properly. Regularly inspect your windows for signs of wear and tear, and promptly address any issues that arise. Additionally, ensure that your windows are correctly installed and aligned to prevent gaps and air infiltration.

Conclusion

Draughts from UPVC windows can cause a variety of problems, including energy inefficiency, discomfort, and noise pollution. By identifying the causes of draughts and implementing the appropriate solutions, you can effectively eliminate draughts and create a more comfortable, energy-efficient home. If you’re unsure about how to address draughts in your UPVC windows, don’t hesitate to seek professional assistance.

FAQs

How do I know if my UPVC windows have draughts?

You can perform a simple test by holding a lit candle or incense stick near the window seams. If the flame flickers or the smoke moves, there may be a draught.

Can I use silicone sealant to fix draughts in UPVC windows?

While silicone sealant can be used to fill small gaps and prevent air infiltration, it’s generally not the best solution for fixing draughts in UPVC windows. Replacing worn seals, adjusting hardware, or using weatherstripping products are more effective ways to address draughts in UPVC windows.

How often should I replace the seals on my UPVC windows?

The lifespan of window seals can vary depending on factors such as the quality of the seal, climate, and exposure to sunlight. On average, you should inspect your window seals every 3-5 years and replace them as needed to maintain optimal performance.

How much does it cost to fix draughts in UPVC windows?

The cost to fix draughts in UPVC windows can vary depending on the extent of the problem and the solutions required. Replacing seals, adjusting hardware, or using draft-proofing products can be relatively inexpensive, while seeking professional help or replacing the windows entirely may be more costly.

Are there any other benefits to fixing draughts in UPVC windows?

In addition to reducing energy consumption and increasing comfort, fixing draughts in UPVC windows can also improve the overall security and durability of the windows. Well-maintained windows with properly functioning seals and hardware are less likely to be vulnerable to forced entry or damage due to weather conditions.
