PVC Windows condensation
As the winter comes, bringing the first lower temperatures, there is often a problem with condensation and moisture on brand new PVC windows, especially on the glass itself, and later effect is that it becomes moldy and fungi all around, which people often band together unfairly with the process of instalation of those PVC windows. Main arguments for such claims is that there were not any of those unpleasant appearances before instalation of PVC windows, while there were just good old wooden joinery. However, the problem of condensation is far more complicated because a few square meters of glass could not anyhow influent the energy efficiency or indoor air humidity, which is the main cause of condensation appearance on window glasses.
There are a few every day examples from life that can clarify this phenomenon, such as glass spectacles, which gets befoged instantly when you enter the warm room after walking outside on the winter day, or the condensation of the windshield in your car when seeral persons enters it after being parked outside on a cold weather. You will not blame bad glasses frame or your car quality for that situations. Condensation in your car is solved by ventilation, and the similar solution shoul be used in your home. Every home contains humidity produced by our every day activities, cooking, showering, laundry drying etc. and the interesting fact is that one man produces for about 2.5 litres of liquid daily for just breathing! Drying of the construction works in enterior could be another cause of humidity in living space. The question is how to make that humidity to leave the room an go outside.
Condensation appearance in rooms
It is a fact that wooden joinery have no influence on microclimate more or less than PVC joinery, and that difference in material is not crutial in ways of air circulation in living space. However, the whole thermal conductivity and permeability in modern construction conditions is far more complex that it used to be, because thermal loss tend to be minimized as much as possible. In old construction projects, humidity was very rarely appearanced, and there were no such problems as condensation and moisture.
That is because humidity in living rooms was formed in conditions where joint sealing of wooden joinery allowed
more air circulation that nowdays, when construction materials were wood, calx, reed, clay etc. which also allowed more air exchange between interior and outside, and the loss of heat was compensated with more heating, so the air circulation becomes even more intense, but all of this was leading to large heating costs. Nowday modern objects tend to be build so the max thermal insulation is achieved, so we have a greenhouse effect in our own home. So, many people wonders on how to solve the problem of condensation in their home.
How to stop, prevent and control condensation
Humidity problems can be solved by instalation of airconditioning systems in frames of joinery, and it provides circulation and air exchange from inside out of your home. But, it is not necessairly that you have to invest any money in solving this problem. The most healthy and cheapest way of humidity prevention is orderly aeration of living space. This action provides fresh and cold air to enter the home, and warm and wet ait to dry and be able to handle more humidity without side effects. Daily aeration will stop humidity accumulation inside your home, and all you have to do is to open the windows several times a day for 4-5 minutes, and the air exchange will do all the work.
