Hansleep Curtains, 1st Grade Blackout, Set of 2, Beige, Width 100cm x Length 195cm, Small Window, Thermal Insulation, Cold Protection, Soundproofing, Energy Saving, Thick, Plain, Stylish, Washable, for Bedroom and Living Room (Beige, Width 100cm x Length 195cm) ◆【First Grade Blackout】These curtains have a blackout rate of 99.99% or more, blocking almost all light from the outside, making the room dark enough that you can't see the expression on someone's face when the curtains are closed during the day. Even with the same grade, the degree of blackout varies depending on the brightness and color of the curtains. Light, pale colors tend to let light through, while dark colors tend to block light. We recommend dark colors for those who prioritize blackout. ◆【About the Fabric】Made of 100% polyester, these curtains are made of thick fabric. They have a soft, smooth feel and a matte texture. With high-performance features such as first-grade blackout, heat insulation, thermal insulation, and soundproofing, the fabric is the same color on both the front and back, making it easy to use as a room divider. ◆【Suitable for All Seasons】Blackout curtains also have the significant advantage of being resistant to heat and cold due to the high density of the fabric. They prevent the room temperature from rising in the summer and from falling in the winter, improving the efficiency of air conditioning and heating. Especially if you use blackout curtains in a room with strong afternoon sun, you can expect to save on your monthly electricity bill. ◆【Triple Weave Technology】The fabric utilizes triple-layer technology, weaving in black yarns, providing excellent blackout functionality. These thick blackout curtains effectively block sunlight and UV rays from the outside.
