What is the difference between Styrofoam and foam board?

The major difference between Styrofoam and EPS foam blocks is that Styrofoam is made from extruded polystyrene (XPS) while EPS foam blocks are made of expanded polystyrene.

Is foam board same as Styrofoam?

Foamboard is made from polystyrene, a popular type of plastic that is also used in the production of Styrofoam. One of the reasons people love foamboards is that they are incredibly lightweight thanks to the polystyrene core of foam board, which is 95-98% air.

Is Styrofoam a foam?

Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called "Blue Board", manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier.

What is Styrofoam board?

Extruded Polystyrene.

This foam board insulation is the rigid pink or blue panels that can be found at home centers in many different thicknesses. It is denser than EPS and provides more R-Value with a rating of 5 per inch of thickness.

What is foam board good for?

Foam board can be used to insulate any exposed cavity in your home from the top to the bottom, and even the walls if you are remodeling and the drywall is down. It can also be installed in the open cavities of your pole barn.

What Is The Difference Between Styrofoam and Expanded Polystyrene EPS Foam?

What is the difference between pink and blue foam board?

Both are manufactured using the same process and contain similar chemical components. The two products also have the same insulating power. However, blue foam boards are manufactured by Dow Chemical Co. whereas the pink foam boards are manufactured by Owens Corning company.

Can you walk on styrofoam?

Question #1 – Can you walk on a foam roof? Yes. Spray foam that's used for roofing is much stronger than the foam that's used for insulation or between walls. In fact, the foam that's used for roofing is closed-cell and has a density of 2.5-3.2 pounds per cubic foot.

What is the problem with Styrofoam?

The manufacturing of polystyrene requires the use of hydrocarbons such as styrene and benzene. These hydrocarbons are released into the air and react with nitrogen oxides to produce ground-level ozone, a hazardous air pollutant. Ground-level ozone can impair lung function and lead to respiratory illness.

Which foam board insulation is best?

Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.

Can Foamboard get wet?

Foam board insulation products are generally considered water and mold resistant but expanded polystyrene foam boards (EPS) have air bubbles that can collect moisture and become wet.

Are there different types of Styrofoam?

Three major types of polystyrene include polystyrene foam, regular polystyrene plastic, and polystyrene film. Amongst the different types of foam are expanded polystyrene (EPS) and extruded polystyrene (XPS). EPS includes the most well-known and common types of polystyrene to include styrofoam and packing peanuts.

Can Styrofoam go in microwave?

While polystyrene foam or Styrofoam containers do a good job in protecting foods in the refrigerator, they aren't made for the microwave. Transfer the food to a microwave-safe container before heating.

What is the strongest foam board?

Gator Board is an extruded polystyrene foam encased between layers of a melamine and wood fiber veneer. Gatorfoam / Gator Board has a much harder outer surface than other foam core boards and resists warping.

Is XPS foam the same as Styrofoam?

As we said, Styrofoam™ is a Dow trade, blue in color, and is an extruded polystyrene (XPS) foam made for thermal insulation, construction and craft applications. EPS is an expanded polystyrene available in various densities for insulation, construction and craft applications and so much more.

How strong is Styrofoam?

How strong is expanded polystyrene? Expanded polystyrene with a density of . 9 pounds per cubic foot has a compression strength of 520 pounds per square foot at 1% deformation.

Does foam board insulation need a vapor barrier?

Foam insulation usually does not require a vapor barrier. For some foam insulation types, such as closed-cell spray foam and foam board insulation, the insulation itself stops the movement of most water vapor.

How thick should Styrofoam insulation be?

Most panels range between 3/8″ and 2.5″ in thickness, though other dimensions and thicknesses are usually available through custom order.

Can I use foam board instead of insulation?

Yes, foam board insulation is an excellent complement to batt insulation. Foam board insulation can add insulation and eliminate thermal bridging when used in wall and ceiling assemblies insulated with batts. It can potentially replace the vapor barrier and house wrap as well.

What can you use instead of Styrofoam?

How long does Styrofoam last?

Non-Biodegradable

According to Washington University, Styrofoam takes 500 years to decompose; it cannot be recycled, so the Styrofoam cups dumped in landfills are there to stay. With enough Styrofoam cups produced each day to circle the earth if lined up end to end, the potential for major ecological impact is great.

Is Styrofoam cancerous?

In the case of polystyrene, tiny amounts of styrene may remain following manufacture and it's this substance that may migrate. In 2014, the National Research Council in the US reviewed the evidence and concluded that styrene is “reasonably anticipated to be a human carcinogen”.

Which side of foam board insulation faces out?

The reflective side of the board should be oriented to the exterior and the non- reflective white side should be oriented to the interior. EXCEPTION: If vinyl siding is to be installed over AP™ Foil- Faced sheathing, install foam boards with the white nonreflective side toward the vinyl siding.
