Causes of condensation on bifolding doors & windows

What are the causes of condensation on bifolding doors and windows? In the Autumnal months, we see many different fluctuations in external temperature. There is a mixture of warm days and colder nights. A result of this is that you may be surprised to see condensation on the outside of your double glazed units.

Causes of condensation on bifolding doors

What causes condensation on bifolding doors?

If you see condensation on the outside of your double glazed unit, it is logical to assume that either your doors are at fault, or there is a problem with your glass.

Condensation is often evident in September and October, but there is no great cause for concern. We offer some information and advice about condensation and what you can do about it.

No new windows or doors eliminate condensation.

The sales message of some window companies wanting to sell you new windows and doors is that you will elimiate condensation.  No new window or door cures condensation.  While double glazed doors or windows with insulated frames certainly help reduce it, other factors cause moisture in the home.

Heating, cooking, living and even sleeping affect moisture levels in the home. Do your research and you will see a standard message amongst professional window and door companies, and the glazing industry bodies that condensation can never be eliminated.

Why do you see condensation on your double glazed windows and doors?

Condensation on your new windows and doors can occur even on the most thermally efficient of products. If you can see the formation of condensation on the outside of your glass, this is perfectly normal.

Condensation on the outside of double glazed units just means that your new energy efficient doors and high specification glass are working together. It is keeping the heat in your home and the cold out.

Why is condensation on the outside not the inside of your doors?

You may be confused as to why you are getting condensation on the outside of your windows, but this is merely demonstrating how useful modern glass is.

On older single glazed windows or timeworn double glazing without insulation, the “cold spot” was previously on the inside of the window. The thermal efficiency of polyamide thermal breaks in the aluminium, argon gas, coatings and warm edge spacer bars in the glass has shifted the cold spots to the outside, where they should be.

Simply put, the heat is now being retained in your property, rather than being lost through the glass or the frames. Naturally, this condensation will disappear as soon as the temperature rises outside.

Tips for reducing condensation in your home.

  • Ventilate your home as much as possible.
  • If you have trickle vents in your windows, do keep these open.
  • Avoid sudden temperature increases – it is better to have a consistent temperature in the home.
  • Ensure you regularly clean off any moisture.
  • Use kitchen and bathroom fans where fitted.
  • Avoid drying washing in the home.

What to expect from frameless glass doors by FGC.

Our unique and patented frameless doors feature the latest in thermally insulated aluminium extrusions and very high specification glass with insulated spacer bars, advanced coatings and a top quality construction.

If you do see condensation on your windows or our doors, there is nothing to worry about.

At this time of year, condensation has formed on the outside of your doors. This is largely due to the increased moisture in the air.

Where your bifolding doors or windows are located is also likely to affect whether you get condensation on the outside and how much. North and South facing properties can differ, your location can be a factor as well.

So if you do see condensation on your new windows and doors, these are doing what they have been designed to do. To keep the heat inside your home.

We also offer a full range of aluminium windows, bifolding and sliding doors,
and front doors as FGC Bespoke Aluminium.

What our customers say

We are delighted with our FGC doors even though the construction of the room is still not yet completed – friends and family visiting our new Garden Room are all commenting vey positively on how amazing the doors look. With the beautiful summer we are having, it is a real pleasure to be able to open up the whole of the front of the room, enjoy the garden and let in the warm summer breeze.

We were very happy with the service offered from start to finish. The frameless glass doors are a perfect solution to our extension and have received many compliments.The workmen who installed the doors were courteous and efficient, the job completed in a few hours, we had a slight problem that needed attending to and this was resolved immediately. We would not hesitate to recommend this company and their wonderful products.

Very pleased with the glass curtain doors which you supplied on time and installed very quickly. Great product that really enhances the

It’s nearly a year since you installed our glass curtains. They have been really great, exceeding our expectations, particularly during the winter months when they were absolutely draught free. When they are fully open you really feel that the lounge is part of the garden, it all becomes one space. Many thanks, they were one of our best decisions.

As it happens, we are still sadly not in the house. We should be however at the end of February which will be great! I can however pretty much respond to the below as I have been able to test the doors. 1. Your performance was excellent from what has been reported by the builders. They mentioned that you were happy to leave you to complete the work and had no problems. They did unfortunately

The bottom line, I am happy with all your support to get me the financial support for this project.  Without your help the project would not have been

The service I received from FGD was professional and prompt from the initial on site survey through to installation and completion. Added to this the finished product has exceeded my expectations. It has enhanced my home with style and individuality, and enabled me to make use of the space in a way that is ‘unique’.

This is the first project I have completed with FGC and it will not be the last. From the original survey and quote, right through to final installation, the team at FGC have been tremendous. The communication and detail is outstanding, the quote was fair market competitive and the final result of the product in situ is absolutely outstanding. I have never seen a system like this before. The quality of the work is remarkable,

Your fitters have just left and we are very pleased with the installation, the door looks even better than we imagined and the guys were really professional. Looks like we will go ahead with the other one. However, we will wait awhile till we are sure it will look ok as it is a taller door. Many thanks to your company. EH

I have to say that although I was not on site to see the finished result, the photographs of the work is remarkable and to add to that compliment, our master builder Chris Seviour reported back to me yesterday that he was so impressed with your team and with the final result. Thank you all for such a tremendous job – I’m hoping to have an article written in Country Living about the house later

I am very happy with the installed doors. The fitters did an excellent job. They arrived on time, were polite and helpful, and went through all of the relevant information with myself and my wife. They also cleaned the windows at the end of the

We wanted to connect two room – a ‘sun room’ and living room -by replacing a large window with some glass doors. We contacted local suppliers and Googled ‘glass partitions’. Local suppliers weren’t much help, however the Google came up with just what we wanted – frameless glass doors. We contacted Gary for a price. He arranged to come and do a survey the following week – 600 mile round trip – arrived on time.
