Understanding Blown Windows Inside Double Glazing Units – By Misted Window Repair Glasgow Professionals
Double glazed windows comprises of two glass panes that are separated by a sealed space filled with air or argon gas. This area creates thermal insulation for your home, keeping the heat inside whilst the cold weather outside where it belongs.
A ‘blown window’ refers to a failure in the seal around the double glazed unit. This causes moisture filled air to enter between the double-glazed window panes, where it gets trapped inside. As temperatures change, the moisture condenses and forms a foggy or cloudy appearance inside the window. And because the moisture can’t escape, it becomes trapped and no amount of cleaning with allow it the escape.
Because of this misty appearance, blown windows are also commonly referred to as misted windows.
It’s important to know that seal failure doesn’t happen overnight. It’s a gradual process that develops over time. Common causes include temperature fluctuations, poor installation, and manufacturing defects of your window frame.
Can I Dry Out Blown Windows Myself?
The short answer is no. Unfortunately, you can’t dry out blown windows yourself.
You may have come across some DIY videos online to ‘fix’ your blown window. But as blown double glazing professionals, we must warn you that these solution are very hazardous and only offer temporary fixes.
If you have a window warranty, you can almost certainly guarantee that trying any of these solutions will void your protection.
The DIY fix you might have come across involves drilling tiny holes into the glass unit to let warm air flow through and dry out the trapped moisture, then sealing the holes again afterward.
This method compromises the window’s insulation properties, releasing any remaining argon gas that was helping to provide thermal efficiency. And because the broken seal hasn’t been corrected, the moisture will re-enter over time.

Why DIY Solutions Often Disappoint
Despite the DIY videos of ‘How to fix a blown windows‘. The truth is that once a sealed unit has failed, it can’t be properly restored using household tools and materials.

If you manage to drill the holes successfully, any improvements to the condensation will only be short-lived as moisture gradually returns through the compromised seals.
That’s why, if condensation forms inside the panes of your double glazing, it’s always best to rely on a reputable company to fix the problem properly.
