Draft-blocking curtains are winter essentials, using dense, multilayered fabrics to form insulating barriers over chilly windows. Thermal linings often incorporate foam or reflective materials that reduce heat transfer, while weighted hems and magnetic side seals prevent cold air infiltration. Ideal for historic homes with single-pane glass or modern spaces with energy-efficiency goals, these curtains can lower heating bills by up to 25%. Look for tight weaves without light gaps—wool and velvet excel naturally. For maximum effect, mount rods wide to cover wall edges where drafts often sneak in. More than comfort providers, draft blockers are sustainability tools, reducing reliance on furnace systems.

MAJGULL Room darkening curtains, 1 pair – light gray

The heading tape has the same color as the curtain so it looks neat from the back as well. The thick curtains darken the room and provide privacy by preventing people outside from seeing into the room.
