Conventional and Acoustic Foam

Differences Between Conventional and Acoustic Foam

Most of us have to deal with noise pollution in various forms right through the day so it is only natural for us to expect sort of method in the sound madness so that it can be pleasant and pleasing to the ears. Thankfully, there are technologies in this field and right at the forefront of such technology is acoustic treatment. You can find more details from FLEXIPOL FOAMS PVT LTD one of the leading acoustic foam manufacturers.

There are many varieties of foams used in acoustic treatment materials for either muffling or refining but it is difficult for a lay person to distinguish between one them or even between conventional and acoustical foam. We FLEXIPOL FOAMS PVT LTD. can provide a clear distinction and help you identify one from the other.

Acoustical foam has the same appearance as other foam materials and even feels the same. However, there are specific distinguishing factors in acoustical foam which makes it stand apart from conventional foams. Here are some of the main distinguishing features:


Acoustic foam panels are engineered to be more durable and are not prone to crumbling unlike other types of foams. It is designed to stand up to all types of poking, brushing and bumping and can be used in the open as well. Conventional foam is unlikely to withstand any rough treatment.


Acoustical foam is designed to absorb sound across all frequencies and hence it offers more firmness than other types of foams. Conventional foams are less firm and hence more likely to have frequency gaps which can affect its performance if used for sound management purpose.

Fire Retarding Capability:

If safety is considered a prime factor, then the fire retarding the ability of acoustic foam can be viewed as one of its key features. Acoustic foam is commonly used in enclosed spaces such as theaters and halls. These places can prove to be a potential fire emanating hazard as people may smoke and there are lamps and candles used at times in these places. Conventional foams do not have the ability to retard fire.

Physical Structure:

One of the biggest differences between conventional and acoustical foam is in the physical structure of the materials. There are tens of thousands of tiny cells in foam. Their size determines the quality and performance of the end products. The more cells per square inch, the better will be its quality. Higher the number; better is its ability to absorb sound. Look at the PPI or pores per inch rating of foam before you buy any type of foam from the leading sheet suppliers India. A rating of 80 is ideal as it means more cells and hence capable of delivering better performance.
