How can I prevent condensation in my home?
Condensation is a common problem, affecting many households across the U.K.
Whilst it’s something that can happen in conservatories, it’s important not to ignore persistent condensation. Condensation can cause damage to paintwork, curtains, wall coverings and window fittings. These issues are encountered across all types of builds but are often a cause for concern in a newly built extension. Condensation is the process of invisible water vapour turning into a liquid. It happens when the temperature of an object falls below the relative humidity of the surrounding air, typically becoming visible on colder surfaces, such as windows. The temperature differences, between the internal and external surfaces of doors or windows, allow for water droplets to develop over time. Condensation isn’t a straightforward problem, the location and amount of water affect the way in which it should be approached.
Why is there condensation in my internal window?
The presence of condensation on an internal window is more than likely a ventilation issue. As the modern building has developed, we have sought to eliminate draughts and create spaces which retain heat. Because of this, the existing, natural water vapour inside of a room becomes trapped. Internal condensation becomes more of an issue in spaces where a larger amount of water vapour is produced, kitchens, bathrooms etc. A solution to this problem can be found by monitoring ventilation.
Why is there condensation on my external window?
Although it appears unsightly, external condensation is largely a positive thing. External condensation means that your windows are thermally efficient. The high performing transparent window coating is doing its job and retaining heat, keeping it inside the room. As a result, the outer pane of glass does not warm to the same temperature. Normally experienced in spring and autumn, this type of external condensation is the product of climatic conditions and thermal efficiency.
How can I reduce condensation in my home?
As most condensation is a ventilation issue, it’s important to reduce the amount of stagnant water vapour in the atmosphere of your conservatory. This does not compromise on the thermal efficiency of your home, as the dry cool air, which is allowed in, is cheaper to heat than the warm moist air.
Internal Condensation Reduction
- Increase the air temperature within the house slightly.
- Provide natural ventilation; opening a window, consider installing an airbrick.
- Ensure that rooms where water vapour is easily produced, such as bathrooms and kitchens, are draught-proof.
- Consider adding a dehumidifier; they can help with water vapour in the atmosphere of your conservatory.
External Condensation Reduction
- This depends on the climate, as the temperature warms, the condensation will disappear itself.
- If required sooner, the only way to remove the condensation will be to physically remove it.
What does it mean when there’s condensation between two panes of double-glazed glass?
Condensation in between the panes of glass within a double or triple glazed window is a failure of the seal. It is a rare phenomenon which does occur from time to time. In the event of cavity condensation, it is likely that the sealed unit will have to be replaced. General Tips for Tackling Condensation
- Consider adding trickle vents. They take some of the water vapour out the room, without compromising the overall temperature of the room.
- Avoid drying your clothes inside. The amount of water vapour released from drying clothes is quite significant. All this water contributes to the humidity of the conservatory.
- Ventilate more regularly. Spaces such as kitchens and bathrooms are more at risk. Any room which produces a significant amount of steam requires more ventilation.
- Install equipment which aids ventilation. Extractor fans, vents or dehumidifiers can significantly improve condensation issues.
- Move plants further away from windowsills. Plants create moisture, trial moving them and see whether they are contributing to condensation.
Most condensation can be reduced or eliminated by tackling stagnant water vapour. Hopefully, this has helped in some way and you feel more confident addressing the issue. If we’ve installed your conservatory, or you’re thinking of adding one, and are cautious about condensation, our team are here to answer your queries and concerns.
