In this blog post, we’re going to help you understand the different types of foam insulation available on the market today. Knowing how each kind of foam insulation works will help you make a more educated decision when considering your purchase. So buckle up, and let’s get started!


Foam insulation is a great solution for soundproofing, because it provides an effective barrier to noise. It also works well for acoustical control and thermal insulation applications.

There are many types of foam insulation available on the market today, but not all foams are created equal when it comes to sound absorption qualities. Some foams only provide good absorption at certain frequencies which makes them less effective when dampening low frequency sound such as that produced by heavy machinery or traffic outside your home or office windows. Other foams used in building materials (such as spray foam) can be quite expensive compared with traditional fiberglass batt designs used by professional contractors in houses across America today — but there’s one type of foam that stands out above all others:

Fiberglass batt construction material has been used in homes since at least 1950 when Dow Chemical Company introduced its first product called “Comfortabel” which was composed mainly from cellulose fibers (wood pulp) plus some calcium carbonate mineral filler material added to increase density levels within each batting unit so that they would stand upright without any support underneath them.”

Acoustic Foam

Acoustic foam is used to reduce sound transmission and absorption. Acoustic foam can be found in recording studios, sound rooms and home theaters. When you’re looking for a foam that will work as acoustic insulation, there are several things you need to consider.

  • What type of acoustic foam do you need?
  • How much space does it have to fill?
  • Are there any special requirements for the material or installation process?

Soundproof Foam

Soundproof foam is a type of acoustic foam that’s designed to absorb sound. It’s made from polyurethane, and is significantly cheaper than other types of acoustic foam. However, it isn’t as effective at soundproofing as other options—if you want the best possible results, we recommend you choose one of our more expensive options instead.

Anti-Microbial Anti-Viral Foam

Anti-microbial foam is a type of sound-dampening material that is designed to help reduce the amount of noise in a room. It accomplishes this by absorbing vibrations and sound waves, thus reducing the amount of noise that reaches your ears.

Anti-viral foam is also a type of sound dampening material, but it differs from anti-microbial foam in one important way: its ability to kill off viruses and bacteria. Anti-viral foam can be used for many different purposes, including preventing cross-contamination between rooms or buildings through its antimicrobial properties.

As mentioned earlier in this article, both types of foam are considered air barriers because they create an airtight seal around your windows and doors. This helps keep out moisture so mold doesn’t grow inside your walls or under floors (which can cause serious health issues). In addition to being used as an acoustic barrier for rooms where people spend time watching movies or listening to music (i..e theaters), these materials are also commonly installed during home renovations when replacing old carpeting with hardwood floors

Closed Cell Foam

Closed cell foam is a great material for sound dampening. It has a low density and is an excellent insulator, sound absorber and thermal insulator. Closed cell foam can act as a good air barrier, moisture barrier and vapor barrier. It can also be used in the construction of walls to reduce echoes and noise transmission.

Open Cell Foam

Open cell foam, also known as polyurethane or polyisocyanurate, has a very different structure than closed cell foam. The open cells of open cell foam are large and allow air to flow through the material. This means that it is less effective at blocking sound than closed cell foam, but much more effective at absorbing sound.

This type of insulation is commonly found in acoustic panels and other types of dampening materials because it’s less expensive than closed cell foam and offers excellent acoustical absorption properties.


Melamine is a type of plastic that can be used to make various products, including foam insulation. Melamine foam is often used as an effective soundproofing material because it adheres well to all surfaces and has good thermal efficiency. It also has good resistance to fire, water damage, and mold growth. However, melamine can be expensive compared to other types of soundproofing materials; this may become an issue if you need large quantities of the product for your home or office project!

Polyurethane Foam Sheets – “Flat Stock” Density Information

Density is the weight of foam per unit of volume. It is measured in pounds per cubic foot, pounds per cubic inch, and sometimes kilogram/meter cubed (kg/m3).

  • Pounds per Cubic Foot (lb/ft3): This measurement denotes how much weight one cubic foot could support if completely filled with foam. For example, 1 pound (lb) = 16 ounces = 453 grams. One cubic foot contains 73072 cubic inches so if you multiply that by 16 oz (453 g) you get 81648 oz or 2216 lbs!
  • Pounds per Cubic Inch (lb/in3): This measurement denotes how much weight one inch can support if completely filled with foam. The equation is simple: divide 2216 by 12 since there are 12 inches in a foot then convert to metric units by multiplying by 1000 because there are 1000 millimeters in a meter (1 m).

Understand the difference between types of foam before making a purchase.

The first thing to understand about foam insulation is that there are many different types of foam available, each one with its own set of properties.

Foam insulation comes in a few basic types: polyurethane, polystyrene and polyisocyanurate. Polyurethane is typically used for interior walls, while polyisocyanurate and polystyrene are used for exterior walls. Foams also come in different densities—the lower the density number, the greater the insulating value of that particular type of foam will be (i.e., an R13 has more thermal resistance than a R20). It’s important to check whether or not your project requires a specific type or grade before making any purchases so that you don’t end up buying something that won’t work well on your project.

Types include open-cell and closed-cell; these refer not just to size but also flexibility–for example “open cell” means air can move through easily while “closed cell” means it cannot–so make sure that whatever kind you need matches up with what we have on hand here at [your company name]. For example: if we only had open-cell but were asked by someone who needed something else then we would have been unable to help them because our inventory wouldn’t include anything from which they could choose!


The buyer’s guide to foam insulation is meant to help you understand the differences between different types of foam and what might work best for you. This guide will help you gain a better understanding of each type so that when it comes time to buy, you know exactly what to look for.
