The LEMOMO Blackout Curtains are constructed using a triple-weave polyester fabric that achieves high levels of light occlusion without the use of chemical coatings. By sandwiching a high-density black yarn between two decorative layers, the fabric reaches a weight of 230 grams per square meter. This design is built to handle daily household use and regular machine washing without the peeling or shredding often seen in foam-backed alternatives.
Usability & Practical Performance
While these panels are designed to significantly darken a room, light rejection is most effective in darker colors like Black or Navy, reaching approximately 95%. Lighter shades provide a room-darkening effect rather than a total blackout. The 1.6-inch stainless steel grommets are built to resist rust, making them suitable for homes in humid or coastal environments. Tests show that the density of the fabric also provides a layer of acoustic dampening, helping to soften street noise by roughly 10 to 15 decibels.
Specifications indicate that these panels measure 52 inches wide by 84 inches long. Because high-density polyester can retain shipping folds, using a steam iron at a low temperature is recommended to smooth the fabric for a finished look. To maximize light blocking, mounting the rod slightly above and wider than the window frame helps manage peripheral light bleed.
- Triple-weave construction provides mechanical durability for frequent washing.
- Stainless steel grommets offer a standardized fit for most residential curtain rods.
- The dense fabric acts as a thermal barrier to help manage window-adjacent temperatures.
If you prefer a shorter length for smaller windows, the NICETOWN 63-inch panels offer similar triple-weave technology in a more compact size.
