When the light is strong, the blackout curtains are hanged at the same time as the ordinary jacquard curtains.
Although it is winter, the sun is very strong on sunny days, and because the angle of the sun is larger in the winter, and the windows of the office are floor-to-ceiling windows, it is very big and really feels dazzling. This also provides a good environment for testing.
It is difficult to see which of the two curtains are placed on the table, because they are all of the same thickness, and the jacquard is still darker.
The light outside is really strong, very dazzling, so there is a clear backlight feeling, the leftmost blackout curtain is basically opaque, the middle jacquard cloth can not achieve this effect, the light transmission is obvious, so it can be very clear The shadow of the window frame, while the color of the base fabric and the jacquard pattern are not visible because of too much light transmission, but the top curtain part is double-layered, and it can be inverted, so the double-layer curtain is also effective for increasing the shading effect. The way! There is actually a roller blind on the far right, and the effect is even worse!
Oh, open the curtains and look at the scenery outside the window. The light came in and the reflection on the table was strong!
The test results, the shading effect of blackout curtains is indeed much better than the curtains of ordinary fabrics, but if the ordinary curtains are double-layered, even if the other layer is a gauze, the effect should be good.
The last thing is: if you don't want to sleep late, don't use blackout curtains.
