Curtain poles usually come with very long stanchions so a lot of light penetrates at the sides of the curtains and heat leaks out the same way. By shortening the stanchions, the curtains are brought closer to the wall and the room is. darker and warmer. This is a cheap and fast way to save on heating bills and to stop light from entering a room when it’s not wanted.

These stanchions were almost 100mm long but now they are 25mm so the curtain hugs the wall, so light stays out and heat stays in. This is a cheap option with no drawbacks. I can modify your existing curtain poles quickly so call me for a price for multiple poles.
