Keeping out the cold

January5

Travelling around the Czech countryside at night can be a voyeuristic experience. Between here and Tabor there is just one other house that has anything other than net curtains. I’m confused – why have net curtains for privacy in the day, but not proper curtains for privacy at night? Is this some communist legacy I’m yet to figure out? And in a country where night time temperatures frequently dip to double figures below freezing. People have so much faith in their new PVC double glazing. Curtains are clearly out of fashion.
When we first arrived at Nový Mlýn every room had net curtains on the windows – but as is the style in the Czech Republic, nothing more insulating than that. Coming from a country where fuel prices are so high that subsidies have been introduced to stop old people freezing to death in the winter – this seemed to miss a trick. Each window has two layers of glass separated by a large gap – however despite this insulating air the temperature of the glass is much lower than that of the walls – hence this is where any condensation forms if the room is damp. To address this, in 2009 I put up the most inexpensive quilts from Ikea as an insulating layer under decorative curtains in each room.
The evidence of effectiveness is only anecdotal – I’d need to build a house inside to test the method robustly – however several times ice formed on the inside of the window behind the curtains (yes – this means the air is damp – a job to be added to the list), despite the room temperature being a comfortable 18 degrees centigrade. They certainly hold warmth in the room.
One drawback of the Ikea quilts has been that they appear to be covered in a material that degrades in sunlight – literally turning to dust – a far from ideal property for curtains, so in 2010 I purchased 50 metres of calico cotton to recover them – it took time, but the result looks sooo much better than they did before. If we’d bought more expensive quilts to use in the windows, they would have looked like quilts in the windows – whereas the calico hangs properly as a curtain. I’ll take them down after the last frost anyway.
In the mean time, I need to make sure that we don’t leave any seedlings on the windowsills behind the curtains over night until there is no danger of the poor things freezing dead.

    Input from native: Proper modern double (or triple) glazing is way more effective than curtains. My windows are just a tad colder than inside walls in big freezes, so if you put money into the windows, you don´t have to put your money into the curtains.
    Double windows itself is around from 18. century and stayed till today due to its effectivity, wich is way better than curtains. Don’t you think that people would pay arm and leg for expensive windows, if they could just put curtains up with the same effect?
