But, using our 4’ x 6’ example that curtain would now be 24 pounds. A good substitute would be a reinforced MLV material as that has a density of 1 lb psf. There are thicker MLV on the market but using a thicker version does not reduce the tearing aspect. Finding a way to hang it could also be problematic, as it could result in tearing if grommets are used. In a window application that amount of weight is substantial. Using a 4’ x 6’ curtain as an example would result in a curtain that weighs 12 pounds. The thinnest MLV we stock is ½ psf density that translates into a weight of ½ pound for every 12” x 12” piece. At GLT Products we manufacture and sell MLV from ½ lb psf to 2 lb psf density. MLV is a dense polymer material that is used extensively in industrial and commercial applications. But what if you are unable to follow any of these recommendations and you’re trying to find a solution to the excessive street noise leaking through your windows? The answer might seem to be MLV in a curtain form. There are a number of remedies that can be undertaken, such as: removing yourself from the situation, wearing hearing protection, reducing the noise from the source, or treating the environment to reduce the noise that is the root cause. Exposure to high sound levels results in the development of noise-induced hearing loss, which can be a serious physical, psychological, and social problem. We all know that excessive noise can damage hearing and pose a threat to our well-being. Let’s dive into those drawbacks for this application. The short answer is that it could potentially work, but there could be some drawbacks. Recently we received an inquiry on whether or not mass loaded vinyl (MLV) is effective at blocking sound through windows. Our sales email is often filled with some interesting questions.
