Here we look at the various ways condensation shows itself on Vacuum insulated glass:

Condensation can manifest itself on glass in a number of ways. Anyone that has lived in a home with single glazing knows only too well that, come the colder months, condensation forms on the inside of the glass. This needs wiping off each and every morning for fear of water puddles on the window ledge.

This internal condensation is also the cause of a great deal of rot on timber windows as the water runs down, sits on the timber ledges and gets behind the putty. Left to extreme it can also cause growth of mould.

It has to be remembered that condensation is a natural phenomenon. The air we enjoy is laden with water. Normally, at warm temperatures the air is able to hold that moisture without problems. Once the temperature drops the air can no longer hold the moisture (it’s dew point) and will deposit it on the coldest surface which is usually the window glass.

Particularly during the night as we sleep we breathe out copious amounts of moisture laden air, around 7 litres per person, which hits the cold surface. This happens whilst the heating is off and doors are closed, and creates the familiar misty condensation when we wake up.

Advantage of Double Glazing Vacuum insulated glass:

Double glazing your windows will prevent the deposit of condensation on the Vacuum insulated glass. Importantly double glazing does not cure condensation but it does enable the room temperature to remain higher so reducing the impact.

With modern high performance double glazing and particularly Vacuum Insulated Glazing, the heat transfer from the inner to outer pane is so good that the outer pane does not heat up a great deal. This leads to condensation, particularly in the Spring and Autumn, being deposited on the outside of the outer pane. This is a sign that the double glazing is working well. This normally clears away once the sun comes up.

You may also see condensation on the outside surrounded by a clear ‘border’. This is because heat transfer is greater through the window frame so the outer pane is heated by the transfer of heat from the frame edge.

Remember: Internal condensation is bad, external condensation is good. Hope so this article will help regarding various ways condensation shows itself on Vacuum insulated glass.
