Features of the fabrics used for rolled curtains
Fabrics that are used in the manufacture of tissue rollers are impregnated with a special solution, which has dust-repellent properties. Therefore, behind the light filters "upside down" is very easy to care for which you can use the usual vacuum cleaner, including it for minimal power. In the case of significant contaminants, they can be removed by a soft sponge using detergents that do not contain chlorine.
The fabrics used in the manufacture of light filters that open upwards, depending on the degree of light, can be divided into three groups:
- Transparent, capable only to disperse sunlight. They are often used simultaneously with conventional tissue curtains.
- Translucent, partially transmitting solar rays and reflecting warmth. They are usually used if necessary to darken the living room or office, as well as to protect against direct sunlight of plants in mini-greenhouses and winter gardens.
- Lightproof. These are special multi-layer fabrics that completely exclude skipping into the room of sunlight. Most often, they are used to darken bedrooms, children's rooms, conference rooms and other premises requiring complete fencing from light.
Operation in winter
The light filters opening up from the bottom belong to the products intended for operation indoors, so they can only be used at room temperature.
If they are installed in a room that does not heal, then upon the occurrence of cold weather, they should not be used, since in this case the elasticity of the tissue and the adhesive properties of the tape will be disturbed, which was applied during their installation. In such a situation, the light filters "upside down" must be removed from the window and keep in the massacled state until the temperature is normalized.
In the case of purchasing rolled curtains in the winter, it should be installed only after they lie down for some time in the room and warm up.
Thus, the light filters that are attached to the windows from the bottom and when opening are moving up, they will not simply protect the room from bright sunlight, but also will be brought to the interior the necessary "highlight."
