Draughts in double glazed windows can compromise your home’s energy efficiency and comfort. Identifying and fixing these draughts is essential to ensure your windows perform optimally. This article provides a guide to help you identify the sources of draughts and offers solutions to fix them.
Identifying Draughts
- Feeling for Air Leaks: One of the simplest ways to identify draughts is by feeling for cold air around the window frame. On a windy day, place your hand near the edges of the window to detect any air leaks.
- Visual Inspection: Examine the seals and frames of your double glazed windows for any visible gaps, cracks, or damage. Look for signs of wear and tear that could allow air to pass through.
- Using a Candle or Incense Stick: Light a candle or incense stick and hold it near the edges of the window. If the flame or smoke flickers, it indicates the presence of a draught.
- Thermal Imaging: For a more precise identification, consider using a thermal imaging camera. This device can detect temperature variations around your windows, highlighting areas where draughts are present.
Fixing Draughts
- Replacing Seals: The most common cause of draughts in double glazed windows is worn or damaged seals. Replacing the seals can effectively block air leaks and restore the window’s insulation properties. Use high-quality weatherstripping or rubber seals to ensure a tight fit.
- Adjusting Hinges and Locks: Misaligned hinges and locks can create gaps that allow draughts to enter. Adjusting or tightening these components can improve the window’s seal. Ensure that the window closes securely and evenly.
- Filling Gaps and Cracks: Use caulk or expanding foam to fill any gaps or cracks around the window frame. This can help prevent air from leaking through and improve the overall insulation.
- Installing Draught Excluders: Draught excluders, such as self-adhesive foam strips or brush strips, can be applied around the window frame to block draughts. These excluders are easy to install and provide an additional barrier against air leaks.
- Repairing or Replacing Windows: In some cases, the draughts may be due to significant damage or a failed seal within the double glazing unit. If the window cannot be effectively repaired, consider replacing it with a new, high-quality double glazed window.
Preventative Measures
- Regular Maintenance: Perform regular maintenance checks on your double glazed windows to identify and address any potential issues early. Clean the frames and seals, lubricate moving parts, and inspect for signs of wear and tear.
- Proper Installation: Ensure that your double glazed windows are installed correctly by a professional. Proper installation is crucial to prevent draughts and ensure optimal performance.

Identifying and fixing draughts in double glazed windows is essential to maintain energy efficiency and comfort in your home. By following the steps outlined in this guide, you can effectively detect and address draughts, ensuring that your windows provide the insulation and performance you expect.
