Initial Consultation:








Causes of Condensation.

Condensation is generally recognised as being caused by the moisture in our homes and the difference in temperature between the outside and the inside of your home. The air inside your home contains moisture from your day to day activities. Showers, cooking and even breathing will add moisture inside your home. When the inside temperature cools down, the air cannot hold as much water vapour. The result is that the water vapour condenses as a liquid and becomes visible particularly on cold surfaces such as windows. By insulating your windows with double glazing you reduce the likelihood of condensation forming on the inside surface of the glass. The moisture is still present in your home though, which is why it is important to also have a well ventilated house.


Adding in Planitherm Low E glass, which is a superior, high performance double glazing, will help retain the heat inside your home even more than standard double glazing will. Planitherm Low E glass works by reflecting the inside warmth back inside the room. Because of the nature of this high performing glass, the outside pane of glass can get cold overnight, and in certain extreme situations, the outside pane of glass can have condensation forming on it. This is not considered a defect of the glass, but is actually a sign that this high performing glass is doing its job by keeping the warmth inside the room. As the exterior temperatures rise, this condensation should clear up.
