As winter approaches, window condensation becomes a more visible issue in many homes across the country. With over 35 years of industry experience, Donwood Glass understands how condensation can impact your comfort, health, and home efficiency. Whether it’s harmless fogging on a cold morning or signs of seal failure in your double glazing, we can address your concerns and ensure your windows are optimal.

Condensation on windows occurs when water vapour cools and turns to liquid on cooler surfaces like glass, more common in colder months due to the temperature differences between inside and outside. There are three main types of condensation: interior, exterior, and between-pane, each affecting your home differently.

What’s normal condensation?
Condensation can be normal in homes, especially in certain conditions. For example, exterior condensation typically forms outside of the glass on cold mornings and is a sign of good thermal insulation. It indicates that the glass is effectively preventing indoor heat from escaping. Another type of condensation that is generally not a cause for concern is minor interior condensation. This type is often seen in high-humidity areas like kitchens and bathrooms and can be managed with proper ventilation to maintain a comfortable home environment.

Signs of problematic condensation
Not all condensation is harmless. Condensation between the panes of your windows could indicate a seal failure in your double-glazing units, which can significantly reduce the insulation effectiveness of your windows. Persistent interior condensation, especially if it leads to water damage or mould growth, suggests inadequate ventilation and indoor air quality. These issues require immediate attention to prevent further damage and ensure the structural integrity and warmth of your home.

If you’re experiencing issues with condensation, Low-E glass, featuring a low-emissivity coating, can help regulate indoor temperatures and reduce condensation. Additionally, insulated glass units with durable seals prevent moisture from entering your home, keeping windows clear and functional.

Managing condensation effectively involves adopting good ventilation practices, particularly in high-moisture areas like kitchens and bathrooms. It's also important to perform regular maintenance checks on your window seals and the overall integrity of the glass. Seasonal inspections can help catch and address issues early, preventing potential complications. 

With the right products and maintenance, you can manage condensation effectively. If you're dealing with persistent issues, consider exploring the options available at Donwood Glass.
