Want to be awakened by the first ray of sunlight in the morning?
But what if it is the first searchlight that wakes you up?
One of the disadvantages of urbanization is that the light pollution at night is too serious, and the stars are not visible at all. This is understandable. But even if the lights are turned off at home, they will still be illuminated by the lights outside. This will be bad for sleep.
If you do not sleep well and are sensitive to light, then a good shading curtain is a necessity.
However, not every curtain has the ability to block light. There are many curtains that look good, but the shading ability is not very good. Generally, there are three types of blackout curtains, and I will analyze them for you today.
The first category is called black silk blackout curtains
The feature of this type of curtain is to add a black silk shading layer between the two layers of cloth, so that it has a shading effect.
However, the main function of shading depends on the thickness. The thickness of the curtain fabric is usually measured by the weight per square meter. For example, 180 means that 1 meter of cloth weighs 180 grams. Generally, the weight of ordinary curtains is only about 90, and the one that can reach 180 grams is actually better. The shading effect is already there, but it is not completely shading.
What does full shading mean? That is 98%-100% shading, which generally requires a weight of 280 grams per square meter.
The 45 woven fabric has reached this weight.
The second category is called white silk blackout curtains
If you like some light-colored curtains, then this white silk is more appropriate. But in the final analysis, the shading of curtains is not only related to the material, but also to the thickness.
The third category is coated blackout curtains
This type of blackout curtain is the main product in the low-end, but the price is not cheap. The coating may decompose under direct sunlight, decompose harmful substances, and damage the human respiratory tract and lungs. If you are not careful, the lungs may become adsorbers for these harmful substances.
To give full play to the powerful shading function and environmental protection at the same time, the heavy dark black silk interlayer curtains will definitely fulfill the mission.
