Best-Rated Blackout Curtains vs Thermal Panels for Winter (2026 Comparison)
If you’re focused on keeping heat in and cold drafts out this winter, choosing between standard-length blackout curtains and full-length thermal panels matters. This head-to-head comparison tests three LEMOMO curtain sets with energy savings, draft blocking and real customer feedback in mind. You’ll learn which size and features trap warm air best, which fabrics perform for insulation, and how to match curtain length to window height. Products were selected from the same family (same weave and fabric) so the differences come down to length, finish and color options — the most important factors for winter comfort.
Quick Answer
For winter energy savings and draft blocking, the LEMOMO Blackout Curtains 66 x 95 inch (ASIN B0BJ1TT556) are the best pick because their floor-length panels reduce cold drafts at the sill and provide stronger insulation. If you have standard-height windows and want a premium look, the LEMOMO Khaki 66 x 63 (B0F879MHRL) is an excellent alternative.

Frequently Asked Questions
Do these curtains actually save energy in winter?
Yes — the triple-weave polyester panels trap air and reduce heat transfer through the window. Floor-length panels give the biggest improvement because they reduce drafts at the sill; layering with a cellular shade increases savings further.
Will these blackout curtains completely block light?
They are designed to block 85%-99% of light depending on color and mounting. Darker colors and tight installation with minimal gaps provide the closest result to full blackout; some customers report mixed results if panels are too short or if side gaps are present.
How do I reduce drafts around the edges?
Hang curtains wide so they overlap the window frame by 3–6 inches on each side, use wraparound returns or magnetic strips if you have metal frames, and ensure floor-length panels touch the floor to stop cold air from circulating under the curtain.
