This type of curtain is mainly used to prevent the penetration of noise into the room through windows and sometimes even doors, in order for the curtain to be called a curtain preventing the penetration of noise it must have a huge weight per 1m2 and at least 900g per 1m2, if it does not have such a weight per 1m2 it is not a soundproofing curtain but it is an acoustic curtain. Therefore if you are looking for a curtain that will help you against noise look for one that has as much weight per 1m2 as possible.
Soundproofing curtains are usually made of several layers of molton sewn together, but we produce soundproofing curtains in a different way, by sewing a special health-safe filler between two layers of fabric and thanks to this our curtains achieve a significantly higher weight per 1m2.
Don't forget that the heaviest curtain rods can weigh up to 2900g per 1m2 and make sure your curtain rod can support that weight before you buy.
Please also be aware that even if you buy the heaviest baffle curtain and just place it in the window without sealing the gaps between the curtain and the wall, you will lose much of the soundproofing effect, because the noise doesn't go through the curtain, but it does go through the gaps between the wall and the curtain, so we recommend using a system to press the curtain as close to the wall as possible when it's pulled so that the sound doesn't go through the gaps between the wall and the curtain.
Due to their high weight and thickness, soundproofing curtains also serve as acoustic curtains, thermal insulation curtains and blackout curtains.
