			<![CDATA[We have just moved into a 300-year old house.  In the bedroom, there is an original stone mullion window - three panels of each, with the vertical pillars in stone, but the panes separated horizontally in two by a metal bar.  The glass is very thin, and very prone to condensation - even if we leave them open overnight (which I don't quite understand...).  The water which collects can be considerable, collecting on the stone sill and running off - clearly a long-term problem, as there is mould.<br /><br />How best to deal with this attractively?!<br /><br />June]]>

			<![CDATA[There's no solution, just ways of mitigating the problem.  Increase ventilation in the house and reduce sources of humidity.  Open bathroom window when showering, kitchen window when cooking, dry your washing outdoors etc, get a dehumidifer.  Some of these measure increase you carbon footprint so maybe it's best to just wipe the window with a tea towel.]]>

			<![CDATA[I am facing the same problem and looking at secondary glazing.  The condensation is caused when the moisture in warm, relatively humid air suddenly cools and condenses on your cold window.  Secondary glazing will help keep the warm air away from the window and also reduce heat loss/save energy.  Of course, secondary glazing doesn't look fantastic, but it can be removed in the summer and, hey, life is full of compromises.  Try Storm Windows for a look-see, but there are other companies who also market their systems on the basis of minimum impact on historical windows.]]>

			<![CDATA[I have this problem everywhere in my stone cottage. It is very bad in the bathroom. The idea of a fan or an open window is a no-no because of the high winds around here. I am cogitating on the idea of a "cold" panel to actually generate condensaton that can be drained away. If it is cooled by the flow of the cold water, it will not cause any carbon overhead. Any one got any comments or better ideas?<br />           Frank]]>

			<![CDATA[Tony I have a cheap mains powerd De- humidifier,  its a load of junk also I think that building in a system that is totaly passive, silent, maintenance free and free to "run" is a no-brainer. Another way to go is a venting system with a heat exchanger to transfer the outgoing heat into the incoming  air. I have looked at the various model as featured in another thread. The problem is that the manufacturers talk about "up to 80% heat recovery", not what they will actually do in practice.<br />  I am open to other peoples experiments and/or experiances.<br />          Frank]]>

			<![CDATA[Whole house ventilation could and almost certainly would work well but it is more expensive than the other suggestions especially the tea towel one.<br /><br />Everyone else wastes 100% of their ventilation losses so turn down the fan speed on your system and you will win big time.]]>
