Condensation on Sash Windows

As Winter approaches the weather is getting significantly cooler. This can lead to problems occurring in your home such as condensation.

What is Condensation?

When warm moist air comes in contact with a cold surface such as a window this can cause condensation to develop. The water vapour in the air turns into liquid and collects as droplets on the cold windows.

What Causes Condensation?

Condensation is formed when there is a high level of moisture in the air. The more moisture that there is in the air, the more likely it is that condensation will form. Carrying out day to day tasks such as washing, cooking, showering and even just breathing can all cause it. Single glazed windows are a primary cause of condensation as they have a cooler inside surface temperature than double glazed windows, which are better insulators of heat. With single glazed windows, the only thing separating your home from the cold outside environment is one pane of glass. When warm air meets cold windows condensation will form.


The Damage it Can Cause

If you don’t do anything about the condensation in your home it can cause mould and musty odours to form. This can also potentially cause respiratory issues. The consequences if left untreated can be a contributing factor to ill health. Particularly for the elderly and young children. It can cause timber decay,  damaged window panes and reduce the lifespan of a window.


How to Prevent / Reduce it

There are three main factors governing condensation. The moisture content of the air, the inside room temperature and the outside temperature. While there is no way to control the outside temperature, the first two factors can be controlled to help prevent it from forming in your home.


Inside Room Temperature

  • Reduce condensation by stopping your windows from getting cold. By replacing your single glazed windows with double glazed windows, you can control the indoor room temperature of your home. The room side surface temperature of the double-glazed windows in a heated house would be warmer than that of single glazed windows. Therefore, the likelihood of condensation forming on your windows is reduced.


Reducing The Level Of Moisture In Your Home

  • When cooking try to use an extractor fan and keep the kitchen door shut to stop steam and moisture escaping into other rooms in the house.
  • Use lids on your pots and pans when cooking food.
  • Open the windows every morning for an average of twenty minutes (Even during winter)
  • Don’t dry your clothes inside as water evaporating from the clothes adds excess moisture to the air in your home
  • Don’t overfill your cupboards in order to let air circulate and eliminate mould.
  • Invest in a dehumidifier to remove moisture from the air.
  • Improve ventilation in your home

I ordered 15 sliding sash windows for my home refurbishment project and had my builder install the windows for me. I think I spent hours playing around with the different design options on the window builder! I absolutely love my new windows!
