Do aluminium windows and doors get condensation? 

by | Feb 21, 2023 | Homeowner Advice, Resource Centre

Condensation can occur on all windows and doors, whether they have been manufactured from aluminium, PVC-U or timber frames.  If condensation is happening on your windows, the question you need to ask your is where the condensation is happening. Answering this question will tell you whether the condensation is a problem or not.

Do your aluminium windows and doors get condensation outside? 

Condensation occurs when the temperature on one side of the glass is higher than the other side. Condensation on the outside of your windows and doors is a good thing. It means it is colder outside your home than it is inside, so your windows and doors are doing their job.

Do your aluminium windows and doors get condensation inside?

Condensation on the inside of your aluminium windows and doors can also be normal. To improve the energy efficiency of our homes, we are insulating them more and sealing more of the ventilation gaps.

However, we also generate a lot of moisture in our homes – cooking, washing and even breathing! In the winter, we don’t tend to open our windows and doors much, so there is nowhere for the moisture to go. It therefore settles on the coldest surface in a room. This is almost always the windows and external doors, no matter how thermally efficient they are.

We recommend airing rooms regularly to keep condensation levels down. The cold, dry air you let in will be cheaper to heat than the warm, damp air you are letting out, so there is no need to worry about this.

While condensation on the inside is normal, it can become a problem. The lower the thermal efficiency of your windows and doors, the worse the condensation is likely to be. If left untreated, it can lead to damp and mould, which is bad news. Modern aluminium windows and doors will help to keep condensation to a minimum, improving the look and feel of your home, as well as protect the fabric of the building.

Do your aluminium windows and doors get condensation between the panes? 

It is a bad sign if your windows and doors get condensation between the panes. Double glazed units are sealed, trapping a layer of air between the panes. It is this air that makes them so thermally efficient. If there is moisture between the panes, it means the seal is broken, which means they will be less thermally efficient and aren’t doing their job properly.

It is possible to repair the seals on double glazed units, but it might be a false economy. You may get better savings in the long term by upgrading to the latest aluminium windows and doors which are likely to be much more thermally efficient than your original units.

Modern aluminium windows and doors get less condensation 

Early aluminium windows and doors had a bad reputation for causing condensation. Those days are long gone. The latest aluminium windows and doors are very thermally efficient, which helps to keep condensation to a minimum.

Our aluminium windows and doors benefit from the latest in “warm edge” technology. The glazed units are filled with argon gas, which adds even more insulating benefits. Using low-emissivity glass (often called low E glass) helps even more.

All our aluminium windows and doors meet – and often exceed – the minimum thermal efficiency requirements of Building Regulations.

The added benefits of aluminium windows and doors 

Modern aluminium windows and doors are not only exceptionally thermally efficient they also offer outstanding aesthetics. From their slim frames that maximise light to the wealth of colour choices, aluminium windows and doors will enhance the look of your home. Aluminium doors are strong and durable too, giving you peace of mind in the security of your home.
