One of the "healthy" performances of curtains: Are your curtains soundproof?
Can your curtains help you sleep well? Moderately keeping the room dark and quiet is helpful to improve the quality of rest. Our first concern is the sound insulation effect of curtains. According to insiders, the choice of double curtains or soundproof curtains can not only prevent light from "slipping" into the room prematurely, but also have a certain noise reduction effect.
Even if we stay in our own home, it is not absolutely quiet around us. When the continuous indoor noise pollution exceeds 30 decibels-equivalent to the volume of the ear canal when whispering, people's normal sleep will be disturbed. However, if people continue to live in a noise environment above 70 decibels, their hearing and health will be seriously affected. According to this standard, our home is actually full of noise. However, compared with the noise of cars and the roar of factory machines for years, the damage to our health is hidden, and it is more difficult for us to prevent it.
The sound absorption effect of fabric curtains is very good, and cotton and hemp are the best materials. Generally speaking, the thicker the curtain, the better the sound absorption effect. Good quality curtains can reduce 10%-20% external noise. If you or your family have poor sleep and are sensitive to external sounds, consider using thick cotton and linen curtains.
The second performance of curtain's "health": Why doesn't the shading cloth shade the light?
Shading cloth can block strong light and ultraviolet rays. However, can the blinding cloth really cover the sun? An interior decorator complained to the home edition that the shade cloth in her house didn't block the light. The hostess had to work the night shift, so she specially installed a shade cloth. When using it, she found that the newly bought shade cloth had an odor. She reflected this problem to the merchants. Although the matter was finally solved, she still didn't know what the shade was made of.
A. About styles: Shading cloth can be made into curtains or roller blinds.
According to the sales staff of the curtain shop, there are two forms of shading cloth curtains: one is the door curtain. The shading cloth used is light and easy to fold. Manufacturers generally use velcro to combine curtains and shading cloth selected by consumers into one, so that the coated side faces outward to block strong light. There is also a roller blind. Usually, after special treatment, the shading cloth is added with styling agent to make it flat and full of drape, which can be directly made into roller blinds. These two colors are available in the general market.
B. About materials: formal and informal.
There are three main materials of shading cloth: one is the raw grey cloth on the front, which can be colored, and the back is PVC coating. The price is around 6 yuan/meter, but the environmental protection performance is poor. The second is that PVC cloth is added to the grid-like gray cloth, and the back is also coated, which feels like plastic and is thicker than the previous one, with good shading effect. Disadvantages are brittleness, easy aging and poor environmental protection. The third kind is linen-cotton blended fabric, which is heavy and has good drape, and can be directly made into curtains with good environmental protection performance, but the color is single, and basically only one kind is milky white. At present, the price and material of shading cloth are confusing, ranging from a few yuan/meter to dozens of yuan/meter. Some inferior shade cloths don't even know their origin. The service life of this kind of shading cloth is relatively short, and it is easy to age and become brittle in the sun.
Some regular manufacturers of shading cloth have produced a series of multifunctional green foamed coated shading cloth products. The width of coated cloth ranges from 1.20cm to 285 cm, which is suitable for home use. Compared with ordinary oily shading cloth, this product is non-toxic, tasteless, soft to the touch, sound insulation, heat insulation and flame retardant, which can effectively prevent the invasion of ultraviolet rays and protect human health. Shading cloth produced by regular manufacturers can be divided into three categories according to its shading performance: translucent, suitable for general office places, and able to communicate with the surrounding good environment. Semi-shading, can block the eyes, can not see the indoor and outdoor figures clearly, but there is a sense of light. Full shading, no light at all, suitable for bedrooms and film and television conference rooms. There is a very simple way to identify the shading property of the shading cloth, that is, the shading cloth is illuminated against the light, and the degree of light transmission is clear at a glance.
C. About shading effect: roller blinds are better than cloth curtains.
Generally speaking, roller blinds made of shading cloth have better shading effect than curtains. Because of its good shaping effect, sunshade roller blinds can prevent a ray of light from leaking into the house, but the price of sunshade roller blinds is relatively expensive, usually between 140- 160 yuan/linear meter (width 1 meter, height 1.4 meter to 1.5 meter). However, the price of blinds in some curtain wholesale markets is much lower. Generally, the blinds are between 40-60 yuan/linear meter, but their environmental protection performance is relatively poor.
