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. Choosing double curtains or soundproof curtains can not only prevent light from "slipping" into the room prematurely, but also play 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 "health": Does the shading cloth block the light?
1. About styles:
Shading cloth can block strong light and ultraviolet rays. There are two forms of shading cloth curtains: one is door curtain. The shading cloth used is light and easy to fold. Generally, the selected curtains and shading cloth are combined with velcro, so that the coated side faces outward to block the strong light. There is also a roller blind. Usually, the shading cloth is treated to make it flat and vertical, and can be directly made into roller blinds.
2. About materials:
There are three main materials for shading cloth: one is the raw fabric on the front and the other is the PVC coating on the back. The price is about 10 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 fragile and not environmentally friendly. The third kind is linen-cotton blended fabric, which has heavy weight and good drape, and can be directly made into curtains with good environmental protection performance, but the color is single. The price of shading cloth ranges from ten yuan/meter to tens of yuan/meter and hundreds of yuan/meter.
There is a very simple way to identify shading, that is, point the shading cloth at the light, and the degree of light transmission is clear at a glance.
