Ever Wondered Why Your Windows Get Dewy in the Morning?

We understand that your uPVC windows are an investment, and you want to make sure they're performing at their best. A common question we’re often asked about is condensation on our windows, particularly on the outside. In this blog, we shed some light on the topic.

Understanding Outside Condensation

Let's talk about those mornings when you see dew accumulating on the outside of your uPVC windows. The good news is that a bit of outside condensation on your windows is a sign your windows are doing their job!
Our uPVC frames and double-glazed windows create a thermal barrier, keeping the warm air inside and the cool air outside. This temperature difference, combined with high humidity, can cause moisture from the air to condense on the much cooler outer pane.

"Condensation on the outside of the window indicates the Low E coating is working effectively," says Martin Ball, Director of NK Windows. "This special coating is on the inside of the inner pane, and its job is to trap heat within your home."

The cooler outside temperature meeting the high-performing window creates the perfect environment for a bit of moisture to form on the exterior surface. But don't worry, this is just temporary. The window is designed to handle this, and the condensation will simply drain off the outside surface.

If you're really bothered by condensation on the outside of your windows, you can gently wipe it away with a squeegee. But usually, a little patience and some sunshine will do the trick.

However, if you're concerned about the amount of condensation or have any questions, please don't hesitate to contact NK Windows. We're here to help!

Understanding Inside Condensation

Occasionally, you may get condensation on the inside of your double-glazed windows. This is more likely to happen at night in rooms with high humidity, like kitchens and bathrooms, or in colder temperatures.

This can be easily addressed by increasing the room temperature, using a ventilation system, or dehumidifier.

Bonus Tips to Keep Your Home Comfortable and Moisture-Free

Keep your home feeling fresh and prevent excessive condensation with these tips:

  • Ventilation is key: Ensure proper ventilation in your bathroom and kitchen, especially during moisture-producing activities like showering or cooking.
  • Dehumidify when needed: Dehumidifiers are great for removing excess moisture from the air.
  • Maintain a comfortable temperature: Keeping your home at a consistent temperature above the dew point helps prevent condensation.
  • Dry clothes wisely: Avoid drying clothes indoors, especially during humid weather.

By following these tips and understanding the science behind condensation, you can enjoy the comfort and efficiency of your NK Windows for years to come.
