As any decorator will tell you, curtains make a room — but only when chosen correctly. When it comes to window treatments, it’s a matter of color and fabric, length and lining, and custom-made versus off-the-shelf. With so many decisions, it’s easy to feel overwhelmed, so we asked a few pros for advice on narrowing down the options and selecting the right curtains for your home.
We tested five types of blinds: honeycomb, roman, roller, and aluminium and wooden venetians.
Our blinds were installed within the window frame (with the exception of the romans), so there was no gap (like the one between the back of the curtain and the window frame) to allow a reverse chimney to form. Honeycomb blinds easily topped our testing for all window coverings. Air is a good insulator, as long as it’s not moving, and the honeycomb structure creates a large, still air gap between the cold window pane and the warm inside air. Also, the honeycomb blinds fitted closer to the sides of the window frame than our other tested blinds, which also helped reduce heat loss.
While their public baths may have gone out of fashion, roman blinds are still going strong. Roman blinds were the best window covering after the honeycomb blinds and secondary double-glazing options. A roman blind’s good performance comes down to the close fit it has over the window frame. This good seal, along with a close fit to the wall at the top, helps retain heat.
