In short, your new double glazed windows should not get condensation. However, it’s important to know what’s normal and what isn’t when it comes to condensation. You may assume that if your windows aren’t clear all the time, then there’s something wrong with them. This can sometimes be the case, but only when talking about condensation between the two panes of glass.

To make sure you don’t continue with failed double glazed windows or worry unnecessarily about a ‘problem’ that is actually perfectly harmless, we’ve put together our comprehensive guide to condensation below.

Your new double glazed windows have condensation on the outside

Condensation on the outside of your double glazed windows occurs when the air outside is warmer than the temperature of your double glazing. Outside condensation means your windows are not allowing any heat transfer, so, if you have some condensation on the outside of your windows – relax! It just means your double glazing is doing a great job of insulating your home.

If you are bothered by how condensation looks on the outside of your double glazing, you could simply wipe it away if your windows are within reach. However, the best option is to simply wait, as the condensation will usually disappear when the sun shines directly on your windows.

Your new double glazed windows have condensation on the inside

If condensation forms on the inside of your double glazing, it is usually the result of steam from your shower, kettle, or hot pots and pans used whilst cooking. This is a natural phenomenon where water vapor turns back into liquid when it comes into contact with something cooler in temperature, like your double glazing.

However, condensation on the inside of your double glazing can sometimes indicate above-average humidity levels in your home and you may have a ventilation problem. If water vapour has nowhere to go, it will condense your windows, as well as your furniture, in carpets, and on walls. Excess moisture around the house can be very damaging to your home and to your family’s health. Encouraging air flow and letting fresh air in will naturally improve ventilation and lessen the chance of condensation on the inside of your windows.

 

Quick and easy ways to ventilate your home

  • Open doors and windows.
  • Dry laundry outside, avoid the tumble dryer.
  • Open your windows trickle vents if you have them.
  • Put your windows on the night vent facility keeping your home secure whilst still allowing airflow. (Especially if windows are behind a thick curtain/blackout blind or above a radiator etc.)
  • Keep internal doors open (when not cooking/showering).
  • In winter, open your windows periodically (Only when the central heating is off!)

You have condensation between the panes of your double glazed windows

The appearance of condensation between the panes of your double glazed unit indicates that the windows are not doing their job properly. The air-tight seal holding the insulating gas inside has failed, letting all the insulating gas out. When this occurs, water vapor can get between the two panes.

This means your double glazing can collect moisture, which can lead to further damage to the window, whilst wasting drastic amounts of energy as you attempt to heat your home and replace the heat being lost. New double glazed windows should not be collecting condensation between the panes, and if you have condensation between your panes, you definitely need new windows.

Brilliant company from all we’ve dealt with, right through to the fitters, to the follow-up emails making sure everything was ok. Having used you before and after having work done to my property, I thought you the only obvious choice to return. Was a little worried as I’d had insulated render fitted and was concerned about the removal and refitting into the same size opening, and the damage it would cause. No worries, it seems. Each to their own trade as they say, and I’m glad they managed it and left me in no doubt, another great job done. Many thanks to you all. And see you in 15 years again?

After a fair few months of looking for a good window provider we can say we are one hundred percent happy with Global. They exceeded our expectations from start to finish. Michael with the quote, the lovely ladies from the office and Andy and Josh who fitted our seven windows and front door. Very professional, good quality, quick and efficient work. A pleasure to work with such a team. Our next step is the conservatory with Global. Thank you and well done to all.

Excellent Service

My mum wanted to say thank you so much for the fantastic service Global windows have given her following her burglary. From start to finish they reassured her the replacement patio doors would be robust and fitted as quickly as possible to ensure the property was secured. On the day of fitting the fitters arrived promptly and installed the doors with no mess. The gentleman who organised this from Global (sorry she couldn’t remember his name) came out to check the doors and to see mum was happy with them brought her a beautiful bunch of flowers. Mum was over the moon. Thank you so much.

We decided to re-use this Company despite moving house and County. Global were helpful and very professional at all stages of the installation. We found all their staff friendly and knowledgeable. Dates given, returning phone calls etc. were all met. The price was very competitive, the quality of their products was excellent with a good range of colours and styles. The fitters were very hardworking, managed to get the work done in one day rather than the expected 2, mainly due to the fact they worked as a team, didn’t take breaks and clearly knew their job. Great company.
