Condensation problems with Glass | Vacuum insulated glass

Glass can be affected by condensation in many ways. Anybody who has lived in single-glazed homes knows that condensation can form on the inside of glass during the colder months. For fear of water puddles, you need to wipe this off every morning.

Internal condensation can also cause rot in timber windows. The water that runs down onto the timber ledges, and then gets behind the putty, is called internal condensation. It can also lead to the growth of mould if it is not treated properly.

Condensation is a natural phenomenon. Water is what makes the air we breathe. At warm temperatures, the air can hold this moisture without problem. The moisture is released onto the coldest surface, which is often the window glass.

We exhale a lot of moisture-laden air at night, approximately 7 litres per person. This is especially true when we are sleeping. This occurs even though the heating is turned off and the doors are shut, and it creates the familiar misty condensation upon waking up.

Double Glazing Vacuum Insulated Glass:

Double glazing windows will prevent condensation from forming on Vacuum insulated glass. Double glazing doesn't cure condensation, but it allows the room temperature to stay higher and reduces the impact.

Modern high-performance double glazing, and especially vacuum insulated glass manufacturer, heat transfer is so efficient that the outer pane doesn't heat up much. Condensation can form on the outer pane, especially in the spring and autumn. This is an indication that double glazing is functioning well. This usually clears up once the sun rises.

Condensation may be visible on the outside, surrounded by a clear "border". This is due to heat transfer being greater through the window frame, so the outer pane of the glass is heated by heat transferred from the frame edge.

Keep in mind: External condensation is better than internal condensation. This article should help you understand the different ways that condensation can occur on vacuum glazing insulated glass.
