How Pelmets drop your heating bills dramatically

I found this to be interesting. It kinda makes sense too... kinda. This assumes that your curtains can't pull air in from the sides near the top. But, perhaps it still helps?

How Pelmets drop your heating bills dramatically

The Pelmet acts as a stopper to this flow of air. The air behind the curtain is still cold and your curtain traps the cold air out, as it should. But as no (or rather very little) air is flowing to the top of the curtain so the thermal flow is stopped and your room stays warmer. Install a pelmet from some spare wood or material and see how much warmer your room is and watch your power bills (and hence usage drop).

Simple, cheap and it makes sense. Give it a go.
