Condens

Formation of condensation inside the thermo-insulating glass:

Condensation can occur on the interior surface of thermo-insulating glass. It speaks in this case of the formation of water perspire or water condensation.

This phenomenon should not be confused with condensation appeared in the space between glasses which represent a very rare case of faulty execution. The causes condensation appearance on thermo-insulating glass, or window frames are listed below.

Inside the house are permanent water vapor:

from breathing the air of a man: 1-2 liters daily quantity;

of cooking: up to 2 liters in a household of 4 people;

household activities bring up to 3 liters in a household of 4 people.

These amounts are permanently as water vapor, invisible in the air. Thus, a cubic meter of air at 0oC may contain a maximum of 5g (representing 5 cm3) of water vapor. If the room temperature increases, the air can receive a greater quantity of water. Thus we have to 20oC to 30oC and 17g to 30g to reach m3.

If there is the maximum quantity of water vapor in the air, then air no longer receives moisture in the form of water vapor and air becomes saturated with air relative humidity of 100%.

As an example, let's consider a space with 15m2 surface and 2.5 m in height with a volume of approximately 38m3. If the air temperature is 23oC, then floating in space, 100% humidity air, almost 1 liter of water in the form of invisible vapor. If during the night in the room temperature drops a few degrees, then a part of the water vapors in the air sit on cold surfaces existing windows or profile.

Also, the formation of condensation occurs when there is room in a lot of humidity and temperature on the surface inside the window is low.

Condensation always starts at the edge of window where there may be areas that are not sealed properly.

Circulation of warm air that "wash" windows can be prevented by blocking the radiator by a roof which leads to the occurrence of condensation on the glass with priority to the bottom.

In rooms less heating it may exist condesation even on thermo-insulating glass, in cold days.

This is because space is saturated with water vapor produced by breathing during the night at a low temperature.

In addition predict that the formation of water condensation can occur not only in windows or window frames, but also on all cold surfaces which leads finally to the formation of moisture and mold on the walls.

Occurrence of condensation can be prevented by following certain rules:

The use of PVC profiles (quality) with 3-5 chambers of air;

Using LOW E glass with argon, which makes heat loss to be 50% lower than in the case of a normal thermo-insulating glass;

A thermo-insulating glass type LOW E, at -10oC outside and +20 oC inside, have +17 oC on inside glass, compared to a normal thermo-insulating glass witch, in the same conditions, have only +9 oC.

Installation of windows in the middle of the interior wall (in the area warm).

Sealing rigorous carpentry on the outlines of frames both interior and exterior.

Air vents frequency of those areas, because modern joinery of PVC or aluminum stop the transfer of the air.

Users of homes that have windows in November, should take account of adapting to new conditions of ventilation. Old windows were usually without sealing and allowing a permanent exchange of air.

In the case of new windows, it is no longer possible the exchange of air out of control, so the residents need to provide additional air vents of the rooms, to prevent the condensation (air vents should be made at least 2-3 times per day).

In winter, the rooms located on the north side are colder. Be careful that these rooms is warmed better than those in the south or to increase their insulation. Also temperatures in your home should not differ from one room to another.

In the morning, the air vents spaces must be done about 20 minutes, and after closing the windows, heat will be uniform and moderate.

Why is condensation on the glass? How can we limit or remove condensation?

Also, use washable wallpaper or acrylic paint, are solutions that substantially reduce the permeability walls, and spontaneous exchanges natural air is no longer producing.

In the context of those shown above, condensation can occur on the interior surface of thermo-insulating glass, and on the frames.

This phenomenon should not be confused with condensation water in the space between the insulating glazing.

In this case, very rarely, it is a faulty execution - something that serious companies (including us) provide the guarantee for 5 years after installation.

Occurrence of condensation in a home can have many causes: human breath; cooking; bath, flowers in the apartment, etc.

Water is constantly in the air as vapor. The maximum quantity of water vapor is in close contact with the ambient temperature. When the air is saturated and the temperature drops a few degrees, for example during the night, some of the vapor is fixed on the cold surfaces in the rooms (windows, frames, etc.).
