4 tips that will help you get rid of condensation permanently

Tuesday / 19 May, 2020

Condensation is probably one of the most unpleasant phenomenon, the appearance of which not only results in the loss of comfort you have in your own home, but can affect both your health and your loved ones and the “health” of your home, leading to black mold on the ceiling, walls, window frame, curtains, cabinets or corners with poor air ventilation.

What exactly is condensation?

You may have noticed often how windows are sweating, especially in cold weather, or the walls of the house are wet to the touch. This is the condensation.

We already know that the air contains different amounts of water vapor. The warmer the air is, the greater the vapor pressure trapped and when the humidity of the air reaches the saturation value, the air cannot hold water vapor anymore, resulting in condensation, generally on colder surfaces in the room, such as windows or the inner part of the walls.

Because of these causes, the condensation is most often associated with the windows of the house, which have the highest coefficient of thermal transmission between the building elements of the house and therefor the lowest temperature of the surfaces of contact with the air in the room.

Factors that make condensation appear inside your home:

  • periods of high humidity, both inside and outside your home;
  • spaces where moisture is produced in a short time such as bathroom or kitchen;
  • very low outdoor temperatures;
  • having many plants in the room;
  • use of materials such as concrete, plaster or sandstone in the building or renovation of the building, which require large amounts of water;
  • lack of air ventilation of the rooms;
  • unheated rooms, which cause the temperature of the surface inside the house and the insulating glazing to decrease;
  • thick curtains in front of windows, which act as a thermal barrier preventing room warm air currents from heating the surface
  • wall covering with non-diffusive surfaces, such as film or wallpaper, which increases humidity inside the house;
  • the sill above the radiator, which prevents hot air currents from heating the glazing

4 tips to help you get rid of condensation permanently

  1. Choose windows with excellent thermal insulation properties

The thermal insulation of your home is more than a passing trend, having long-term implications in increasing your comfort and your loved ones. Therefore, when you equip your home, make sure you choose windows that have superior thermal insulation properties. Types of thermal insulating glazing, along with argon and Warm-edge technology used in the manufacture of thermal insulating PVC and aluminum windows in Stars by QFORT range, have the ability to keep heat inside the house during the cold period of the year and to prevent the greenhouse effect in warm periods. Thus, your comfort is improved and your environment is protected by reducing energy consumption in your home and CO2 emissions into the atmosphere. However, there are certain conditions under which windows with these types of equipment may lead to condensation, but depends on the location, other construction elements and other factors of benefit mentioned above.

Therefore, to avoid condensation, the temperature of the surface of the heat insulating glazing inside the room must be increased. You can do that by choosing wisely windows with a low thermal coefficient.

  1. Take care of cleaning and maintenance of your windows, especially when cold weather

Another aspect you should consider to get rid of condensation permanently in your home, is about cleaning and maintaining your windows, especially when cold weather, but not only. We recommend that you wash the outside of windows regularly with a special window washing solution or hot water and vinegar. Also, after washing them, it is good to use an anti-condensation solution on the surfaces where you have noticed this unpleasant phenomenon.

  1. Control the humidity of the air in the rooms

To permanently reduce and even eliminate condensation in your house, you must reduce the amount of water vapor in the air so that the relative humidity of the air in the rooms is within the normal range, between 30% and 50%. You can do this by using a high-performance indoor ventilation system.

  1. Remember to vent rooms

To vent rooms in your home is one of the simplest and most effective actions you can do to get rid of condensation permanently. No matter the season, remember to vent the rooms at least twice a day, 10-15 minutes each. In addition to these four key tips that you can put into practice right now, consider the other factors that favor the appearance of condensation in homes and try to eliminate them as far as possible.


We hope these lines will help you win in the fight against condensation and we invite you to choose wisely your home windows by consulting our range of thermal insulating windows in PVC and aluminum stars by QFORT.
