Wondering how to stop draughts from uPVC windows?

Having draughty windows can be frustrating and uncomfortable, as they allow cold air to enter your home and compromise its energy efficiency. uPVC windows are a popular choice for homeowners due to their durability and insulation properties. 

However, over time, even the best uPVC windows and doors can develop draughts. In this article, we will explore effective methods to stop draughts from uPVC windows, ensuring a comfortable and energy-efficient living space.

Why Are There Draughts in My UPVC Windows?

To effectively tackle draughts in your uPVC windows, it is essential to identify the source of the problem. Draughts can occur due to various factors, such as:

  • Poor installation: Improper installation of UPVC windows can result in gaps and misalignment, allowing air to seep through.
  • Age and wear: Over time, UPVC windows may deteriorate, leading to gaps and cracks that enable draughts.
  • Sealant degradation: The sealant used to secure the windows can degrade over time, compromising its effectiveness in preventing draughts.
  • Insufficient insulation: Inadequate insulation around the window frames and sills can create gaps where draughts can infiltrate.

Benefits of Draught-Proofing uPVC Windows

Investing time and effort in draught-proofing your uPVC units offers several advantages:

  • Improved energy efficiency: Draught-proofing reduces heat loss, allowing your home to retain warmth during colder months and reducing the need for excessive heating.
  • Enhanced comfort and indoor temperature control: By eliminating cold draughts, you can create a more comfortable living space and maintain a consistent temperature throughout your home.
  • Reduction in energy bills: With improved insulation, your heating system won’t have to work as hard, resulting in lower energy consumption and reduced energy bills.

Now that we understand the common causes and benefits, let’s move on to effective solutions for stopping draughts from UPVC windows.

DIY Solutions to Stop Draughts from UPVC Windows

1. Check and Seal Gaps

Start by carefully inspecting your UPVC windows for any visible gaps or cracks. Here’s how you can address them:

  • Sealing gaps in the frame: Apply a high-quality silicone-based sealant along the frame’s edges to fill in any gaps or cracks. Ensure that the sealant is specifically designed for use with UPVC windows.
  • Using weatherstripping: Install weatherstripping around the edges of the window frames to create an airtight seal. This can effectively block out draughts and improve insulation.
  • Addressing gaps in window panes: If you notice any gaps between the glass panes and the frame, consider replacing the rubber gasket or seal to restore the integrity of the window.

2. Insulate Window Frames

To enhance the insulation properties of your UPVC windows, focus on the window frames:

  • Applying insulation tape: Apply self-adhesive insulation tape around the edges of the window frames. This will help fill in small gaps and cracks, preventing draughts from entering.
  • Using draught excluders: Install draught excluders along the bottom of the windows to create a barrier against incoming draughts. These devices are easy to fit and can be highly effective in reducing draughts.

3. Upgrade Window Glass

Consider upgrading the glass in your UPVC windows to further improve insulation and reduce draughts:

  • Double or triple glazing: Double or triple glazing provides an extra layer of insulation, minimizing heat transfer and draughts. It’s a long-term investment that can significantly enhance energy efficiency.
  • Low-emissivity (Low-E) glass: Low-E glass has a special coating that reflects heat back into the room while allowing natural light to pass through. This type of glass helps regulate indoor temperature and reduces draughts.

4. Maintain and Replace Components

Regular maintenance and timely replacement of certain components can help prevent draughts in UPVC windows:

  • Inspecting and replacing worn seals: Check the condition of the seals around the window frames and replace any that show signs of wear or damage. This will ensure optimal performance and reduce draughts.
  • Repairing or replacing hinges and handles: Faulty hinges or handles can cause misalignment, leading to draughts. Repair or replace these components as necessary to maintain a proper seal.

When To Replace Your Draughty Windows

If you’re constantly dealing with draughts in your home, it may be time to consider replacing your entire window unit. While replacing windows can be seen as a significant investment, it offers several benefits that make it worthwhile. Not only will you enhance the overall appearance of your home, but you’ll also experience long-term savings on your energy bills.

When it comes to visual damage on your window frames or glass, it’s crucial to address the issue promptly by opting for a window replacement. Ignoring the damage will only lead to further complications and inconvenience in the future.

It’s important to note that any damage to your windows creates weak spots, making your home more vulnerable to potential intruders. Visible damages from the exterior can also attract the attention of burglars, putting your home’s security at risk.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
