Thermal curtains feature a special insulating layer that traps air between the fabric and the window, reducing heat transfer. This keeps rooms warmer in winter and cooler in summer.

Properly installed thermal curtains can reduce window heat loss by up to 25%, helping lower heating and cooling costs. They work best when curtains are kept closed during peak heat or cold hours.

Most DWCN thermal curtains also provide blackout functionality, as the insulating lining is typically opaque. Browse our blackout curtainscollection for additional options with thermal properties.
