Condensation in windows is a common problem that many homeowners encounter, especially during the colder months. It not only spoils the aesthetic appeal of your home but can also cause damp patches, mould, and damage to window frames. At Kedleston Glass & Glazing, we understand how frustrating condensation in windows can be, and we are here to help you find lasting solutions. In this guide, we’ll explore how energy efficient windows can help prevent condensation, the types of windows to consider, and practical steps to improve your home’s comfort and energy performance.
Condensation occurs when warm, moist air inside your home comes into contact with cooler surfaces, such as your window glass. This leads to water droplets forming on the glass or frames, which can cause long-term damage if left unaddressed. Older or single-glazed windows are more prone to this issue due to their poor insulation properties.
By upgrading to energy efficient windows, you can significantly reduce the occurrence of condensation in windows. These modern designs help maintain a more consistent indoor temperature and minimise cold surfaces, which reduces moisture build-up.

Energy efficient windows are designed with advanced technologies such as double or triple glazing, low-emissivity (Low-E) coatings, and high-quality insulating frames. These features help retain heat inside your home and prevent the cold air from penetrating the glass, effectively cutting down the chances of condensation forming.
Here at Kedleston Glass & Glazing, we offer a range of energy efficient window options suitable for every style of home. Whether you prefer uPVC windows or more traditional styles like sliding sash windows or Heritage flush sash windows, we have solutions that blend efficiency with aesthetic appeal.
If you are concerned about condensation in windows, selecting the right window style can make a significant difference. uPVC windows, for instance, are well known for their thermal efficiency and low maintenance. The multi-chambered design of uPVC frames helps trap heat and insulate your home, reducing cold spots prone to condensation.
For those who favour classic designs with a modern twist, sliding sash windows and Heritage flush sash windows offer traditional charm while being upgraded with efficient glazing and better seals. These windows preserve the character of period homes and deliver the benefits of improved insulation.
Tilt and turn windows are another excellent choice. Their design allows for better ventilation compared to traditional casement windows, enabling you to reduce indoor humidity levels, which is a major factor in condensation formation.

While upgrading to energy efficient windows plays a key role, it’s essential to manage the internal environment of your home to fully eliminate condensation issues. Maintaining good ventilation is critical. Regularly opening windows or using trickle vents can help reduce moisture build-up inside. Using extractor fans, especially in kitchens and bathrooms, also aids in keeping humidity levels down.
Heating your home evenly and avoiding rapid temperature changes can prevent cold spots around your windows, which often attract condensation. You may also consider using dehumidifiers in areas prone to dampness.
Finally, ensure your windows are properly installed and sealed. Poorly fitted windows can allow cold air to seep in, worsening condensation problems. This is why professional installation by a trusted company like us at Kedleston Glass & Glazing is vital.
