Expert Advice from Sealtight Windows
Condensation on windows is a common issue for many homeowners, especially during the colder months. If you’ve been searching “how to prevent condensation on windows”, you’re not alone. This problem doesn’t just affect your view; it can also lead to mould, damage to window frames, and a drop in indoor air quality.
At Sealtight Windows, we’ve been helping homeowners across Teesside and the surrounding areas improve their homes with energy-efficient Kommerling UPVC windows, doors, conservatories and orangeries for over 20 years.
In this guide, we’ll explain what causes window condensation and share practical, effective ways to prevent it from affecting your home.
What Causes Condensation on Windows?
Condensation occurs when moisture in the air meets a cold surface, such as the inner glass pane of a window.
As the warm, humid air cools down quickly on contact, it releases water droplets, which form as condensation.
The main causes of indoor window condensation include:
- Cooking, bathing, and drying clothes indoors
- Poor ventilation or inadequate airflow
- Single-glazed or old, inefficient windows
- Temperature differences between inside and outside
While some condensation is normal, persistent moisture can lead to mould growth, peeling paint, and long-term damage, especially to timber frames.
How to Prevent Condensation on Windows
If you’re dealing with condensation on your windows regularly, here are proven strategies to prevent it:
Improve Ventilation in Your Home
Good airflow is essential to prevent excess moisture from building up indoors.
- Open windows regularly to let stale air escape
- Use extractor fans in kitchens and bathrooms
- Avoid blocking air vents or trickle vents in your windows
- Consider a mechanical ventilation system if condensation is severe
Use a Dehumidifier
A dehumidifier removes excess moisture from the air, particularly helpful in winter or in rooms that naturally hold more humidity, like bedrooms and bathrooms.
Upgrade to Energy-Efficient Double or Triple Glazing
Modern Kommerling UPVC windows use high-performance double or triple glazing with warm-edge spacer bars and gas-filled sealed units. These advanced windows:
- Reduce heat loss
- Minimise cold surfaces
- Lower the chance of condensation forming on the inner pane
If your windows are older or only single-glazed, upgrading can drastically improve your home’s thermal performance and comfort.
Keep Your Home Heated Evenly
Condensation is more likely when parts of your home are cold and underheated.
- Maintain a steady, low-level heat throughout the day
- Use thermostats and timers to avoid cold spots
- Heated conservatories with LivinROOF installations are especially resistant to internal condensation
Dry Clothes Responsibly
If you’re drying clothes indoors:
- Use a tumble dryer with proper ventilation
- Keep windows open in the room during drying
- Avoid drying clothes on radiators
Install Trickle Vents
Trickle vents are small ventilation openings in modern window frames that allow fresh air to flow through your home without needing to open windows fully.
Sealtight’s modern UPVC windows come with optional trickle vents to keep your home naturally ventilated all year round.
