Window Treatments
Thermal Curtains
Thermal curtains are designed with insulating backing or specialized weave that helps regulate room temperature by reducing heat transfer through windows. This technology keeps rooms cooler in summer and warmer in winter, potentially reducing energy costs by up to 25% while improving comfort.
The insulating layer—often foam, acrylic, or multiple fabric layers—creates a barrier against drafts and radiant heat. While thermal curtains may not provide complete blackout, they significantly reduce light and outside noise while offering practical energy savings that justify their cost over time.

Placement & Usage Tips
For maximum efficiency, thermal curtains should fit closely to walls with minimal gaps. Install on windows that receive direct sun or are drafty. Keep closed during peak heating/cooling hours.
💡 Pro Tip
The most effective thermal treatment combines cellular shades (honeycomb) directly at the window with thermal curtains layered in front. This creates multiple insulating air pockets that dramatically improve temperature control.
