Hansleep Curtains, 1st Grade Blackout, Set of 2, Beige, Width 100cm x Length 210cm, Small Window, Insulation, Cold Protection, Soundproofing, Energy Saving, Thick, Plain, Stylish, Washable, for Bedroom and Living Room (Beige, Width 100cm x Length 210cm) ◆【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】These curtains are made of 100% polyester and thick fabric. They have a soft, smooth feel and a matte texture. They are highly functional with first-grade blackout, heat insulation, heat retention, and soundproofing, and the front and back of the fabric are the same color, making them easy to use as a partition. ◆【Suitable for All Seasons】Blackout curtains have the significant advantage of being difficult to transmit 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. 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 threads, providing excellent blackout functionality. These thick blackout curtains have the function of firmly blocking sunlight and ultraviolet rays from the outside.
