In the past, I would have recommended using open cell foam for many of these projects. That all changed when I discovered closed cell foam, which is more durable and comes in a variety of densities. Choosing the foam that is right for your project can be difficult, but luckily there are a lot of resources out there to help you pick the one that will work best for you. The pros at Foam Factory, Inc. helped me learn about all of these uses so I could be sure to recommend them to my readers!

Window and door insulation

Insulating your windows and doors can help keep the heat in during the winter, reduce drafts and noise, and even function as a draft stopper when it’s really cold outside. It’s important to know that there are two different types of closed cell foam: one that is pre-cut for insulation purposes (i.e., an S-shaped piece of foam), and another type that is used as a sealant. Both types are good for insulating window frames and door frames because they provide airtight seals to prevent air from leaking out of areas where it shouldn’t be escaping. However, if you’re looking for something smaller than an S-shaped piece of foam—something more like 1/4″ or less in thickness—it will be best suited as a sealer rather than as actual insulation material because it won’t add any additional R-value into your home (R-value refers to how much thermal resistance material provides against heat loss).

This type of closed cell foam can also function well as a draft stopper when used around doors because doorways tend to let air flow through them even when closed tightly; this makes it easy for cold drafts from outdoors enter inside homes during winter months without proper precautions taken beforehand!

Closed cell foam is highly versatile enough even within its own category based on price point alone ($30–$40 per package). This means that anyone interested in purchasing this kind may have some choices before them depending upon what exactly they’re looking at doing with their purchase once they’ve made it home safely after shopping trip 🙂

Roof underlayment and siding

Closed cell foam is a great choice for roof underlayment. It provides an airtight seal between the roof and wall, which helps to prevent water damage. It also keeps moisture from making its way into your home through vents and exhaust fans. You can get closed cell foam in rolls or sheets that are easy to cut with a utility knife.

The best part about closed cell foam is that it’s highly durable, so you don’t have to worry about it being damaged by heavy objects like snow loads or wind gusts!

Caulking and gaskets

  • Caulking and Gaskets

Closed cell foam can be used to seal gaps in walls, floors, and ceilings. This is a great way to save money on your heating bill by sealing up any places that air leaks into the building. It’s also good for caulking around windows and doors if you want to prevent drafts from getting inside. If your pipes are making noise or there are gaps between them and their casing, closed cell foam can help make them quieter while keeping moisture out of the structure of your home or business. If there’s an air vent in an area with high humidity (like near a shower), then applying some closed cell foam will prevent mold growth from happening due to trapped moisture buildup in those areas

Vapor barrier

A vapor barrier is a material that blocks moisture from passing through it.

Vapor retarders, on the other hand, slow the rate at which water vapor passes through it. In general, you use a vapor barrier in areas where condensation occurs and a vapor retarder where air is moving across the surface of an object.

The benefits of using both:

  • Reduces energy costs by decreasing moisture in your home or business
  • Helps keep mold from forming around pipes and drains in walls and floors

Pipe insulation

One of the best ways to insulate pipes is with closed cell foam. Pipes are often located in a variety of harsh environments, including cold, hot, moist and corrosive places. They also experience high vibration and other extreme conditions. With all these factors at play, it’s no wonder that pipes can be difficult to keep warm and dry!

Closed cell foam will go a long way towards solving this problem by providing insulation where it’s needed most: around your pipe. And because it’s flexible enough to conform around the bend of your pipe without bunching up or cracking – unlike rigid insulation materials – you won’t have to worry about how much space there is within that bend or if anything else needs wrapping up at the same time (like electrical wires).

Marine flotation

In marine flotation, closed-cell foam is used to increase the buoyancy of boats and other vehicles. This can be done by adding it to the hull of boats or by creating a cavity for it within the boat itself, which will keep it afloat even if most of its structure is submerged underwater. A lot of people who work in this industry are familiar with closed-cell foam because they use it all the time in their line of work.

Because closed-cell foam is so buoyant, it makes sense as an ingredient for marine flotation: It means that any vehicle that includes this material will remain afloat even when filled with water up to its limit. This characteristic also means that these products are durable enough for everyday use; you don’t need to worry about them breaking down easily or losing their shape over time!

Finally—and perhaps most importantly—closed-cell foam has very low density (meaning that there is little weight associated with each cubic centimeter). In other words: The more space there is inside your vessel’s hulls or cavities, the less dense each individual sample needs to be before they too become too heavy under their own weight alone!

Construction and concrete leveling

When leveling concrete, the ideal material to use is closed cell foam. This is because it stays in place and provides a solid surface for the concrete to be poured on. If you are leveling a slab that has already been poured, it can be very difficult to get rid of all the air bubbles from inside your slab. If these bubbles are left behind after pouring, they will weaken your final product and make it more susceptible to cracks or breaks.

Closed cell foam also helps give structure to your concrete when you’re ready for finishing touches like trowelwork and texture. When used in conjunction with other materials like gravel or sand, closed cell foam will create a flat surface that makes trowelwork more accurate (and thus easier). It’s also great for leveling uneven surfaces because its softness helps absorb some impact before reaching hard surfaces like metal scaffolding poles/walls etc…

Gymnasiums, athletic fields, sports surfaces, dog agility equipment, gun ranges, BB-gun ranges, sound proofing.

Closed cell foam is also an excellent material for gyms. It can be used to create soundproofing in a gymnasium, or it can be used as padding under floor mats and rubber tiles. Closed cell foam is also great for athletic fields, because it’s easy to install and it has a long lifespan. The closed-cell structure of the foam makes it resistant to water absorption and abrasion, which makes it last longer than traditional rubber.

In addition to its use in gyms, athletic fields and dog agility equipment, closed-cell foam can also be used in gun ranges (especially BB-gun ranges) because they make an excellent cushion against impact from bullets or BBs fired from air guns and paintball guns.

Protective packaging or foam inserts for any product

When it comes to protecting your products, there are a lot of options out there. You can choose to use foam inserts or custom boxes. Both are great and have their own advantages, but what if you want more control over how your product is protected? What if you need extra space for shipping or storage purposes?

Then closed-cell foam is the way to go! Closed-cell foam has many applications and uses: from protective packaging or packaging inserts, to shock absorption and insulation.

Closed cell foam is versatile material that has many uses

Closed cell foam is a versatile product that has countless applications and uses. One of the most common ways to use closed cell foam is as an insulator, as it’s both lightweight and waterproof. Closed cell foam can also be used in a variety of other ways, including:

  • Fire-resistant roofing material
  • Waterproofing for walls, basements and crawl spaces
  • A cushion for crates or for people using wheelchairs
  • An easy solution for backpacking, camping or any other activity where you want to protect yourself from bugs or humidity


So now that you’ve read about all the great ways to use closed cell foam, we hope you have some new ideas for using it in your own life. Whether you’re building a home or installing insulation in your basement, this is a versatile material that can get the job done better than anything else on the market today. Not convinced yet?
