They block almost all light from 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. These blackout curtains are perfect for those who are concerned about issues related to light, such as the glare of the morning or evening sun, wanting to avoid UV rays, or being concerned about people outside seeing shadows inside at night. 【High-quality thick fabric】Using high-quality 260GSM thick fabric, with a triple-layer weave, these curtains not only block out light but also block out outside views and have high heat retention and insulation effects. The front and back layers are each made of a twill weave, resulting in a smoother feel and a glossy, thick fabric. The middle layer is woven with high-density blackout insulation yarn. 【Cooling/Heating Efficiency UP↑】These curtains use special fibers that block light and also have a high heat-blocking effect. Therefore, they prevent heat from entering from outside in the summer and prevent warm air from escaping in the winter, which ultimately leads to improved cooling and heating efficiency. They are also recommended for their energy-saving effects. They also maximize the prevention of sunlight and UV rays, preventing the discoloration of furniture and flooring. 【Washable】They are designed to resist shrinking even when washed in a home washing machine. There is no worry of color fading. If you find any dirt, you can easily wash them at home, enjoying clean and comfortable curtains at all times. Due to the high-density and thick fabric, they can also prevent sound leakage to some extent for sounds transmitted through the air.
