Condensation On Inside Of Windows Hermetically Sealed Double Glazing

Condensation inside Double Gazing

Condensation inside double glazing is a concern for most people who have double glazed windows installed in their homes, and it may occur in any type of a house or a building. Condensation is mostly caused due to poor installation and design of the windows, and is most common in single-glazed windows. In double-glazed windows too, condensation inside the double glazing is a constant menace.

Consequences of Condensation inside Double Glazing

Condensation inside double glazing causes the windows to appear as misty, foggy and steamy. It is possible that a musty odor may emanate from the windows, which smells really bad. The painting is damaged by this and it really looks quite ugly. Pools of water may be found lying on the window sills, much to the headache of the homeowner. The window frames deteriorate, need replacing, but the replacements are often costly. There is often a damp and mold growth on the windows, which are not good for the health of those living in the house.

Why Condensation inside Double Glazing is such a big problem today?

While condensation inside double glazing has always been an issue even decades ago, today the problem is more pronounced because of the fact that homes of today are better insulated and have the latest heating systems – which means there is less space for ventilation than the homes of old. No longer do homes have the traditional fire places or the chimneys, which means there are fewer avenues available for the moisture to escape out of the house – which leads to a condensation inside double glazing.

How is Condensation inside Double Glazing formed?

The condensation is formed as the air inside the house containing water vapor meets the cold surface of the windows. Because of the quick fall in temperature, the water vapor is converted into droplets of water, which results in the condensation, causing the windows to appear as misty. Technically, the condensation may be controlled by controlling the water vapor inside the house – by using proper ventilation and extractor fans and by controlling the room temperature inside - by converting the single glazing to double glazing and by increasing the room temperature, which enables the air to hold more water vapor while preventing the condensation.

What are the factors that cause Condensation inside Double Glazing?

There are two main factors that cause condensation inside double-glazing:

# Condensation on the inner glass – This happens because the temperature of the surface of the inner glass of the double glazing is far too low because of high water vapor content within the house.

# Condensation within the two glasses – This happens because the sealing that is used to tightly hold together the two window panes has failed and is broken. This means that there is now space for the water vapor to enter the double glazing.

On purchasing a double glazing unit, the best way to prevent condensation is to always make sure that the temperature inside the house is higher than that outside. This may be done by having proper ventilation inside the house and having exhaust fans fixed as well.

How does converting from single glazing to double glazing control condensation?
Double glazed windows make use of an insulating void in between the window panes, which reduces the heat loss from the inside of the house to the outside. As the room temperatures inside the house are usually higher than those outside, this reduces by a great extent the possibility of condensation occurring as the warm moist air within the room comes into contact with the surface of the glass.
How can one prevent Condensation inside Double Glazing?

The best way to prevent condensation inside double glazing is to ensure that the double glazing unit is installed with care by professionals, so that the window panes are perfectly sealed shut. Homeowners should regularly clean the windows with dry towels or make use of dehumidifiers. Double glazing condensation repairs may also be done where the window technicians have the air holes inside the double glazing unit cleaned – but this is only a temporary solution. The only perfect solution for condensation inside double glazing is to have the double glazing unit completely replaced by a new one.

Condensation On Inside Of Windows, Repairs of condensation within the cavity of a
hermetically sealed double glazed unit
or Insulating Glass Unit (IGU) denotes
a failure of the seal.
Where the double glazing is achieved
by the installation of secondary glazing,
condensation on the cavity surface of the
outer glass generally (but not invariably)
indicates leakage from moist air from the
room into the cavity. However, the reader
should note that it is not possible to
hermetically seal secondary windows;
therefore some migration of air from the
room into the cavity is to be expected.

Condensation can occur occasionally on
the cavity surface of the inner glass when
the sun is shining on the window. This means
that something in the air space itself, such
as an unsealed wooden separator or
desiccant, contains moisture. It should
be noted, however, that this source can
also be responsible for condensation on
the cavity surface of the outer glass.
