No matter what we carry out or wherein we go, having great insulation is just one of the most necessary things in our lives, and also most of the moment we no even conscious of it.

You are watching: Is styrofoam a conductor or insulator

It will always be an important to store our residences warm in winter and also cool in summer, then our offices and other public areas and also of course ourselves.

As us all know, the much more layers we have warmer we will feel and the factor behind this is pure physics – the waiting is a bad conductor of heat.

By wearing many layers much more air is trapped within them and also since air cannot conduct warmth it immediately stays about us.

This is precisely why Styrofoam presents exceptional insulation - that is composed greatly of waiting which makes up around 98% of it, creating a perfect barrier between the object the it insulates and also the surrounding area.


How does Insulation Work?

Let us an initial cover part basics come understand much better how Styrofoam works.

There room three mechanisms through which warm is spread and they are referred to as conduction, convection, and radiation.

The easiest means to describe these 3 is to imagine a pot with water the is being boiled ~ above a stove.

Conduction happens once warmth moves v a material, for instance when warmth move from the bottom of the pot to the manage that it s okay heated and warmth is then transferred with straight contact.

Convection happens once the warm gets dispersed through liquids and gases, for example, through water that is around to begin boiling and this happens thanks to movements of numerous molecules.


Radiation is the third mechanism despite which heat is sent in the type of light ray or waves. Because that example, though radiation warmth is moved from the flame to the pot.

How does Styrofoam Work?

Styrofoam is the trademarked term developed by the agency The Dow Chemical agency in 1941 and it is supplied for polystyrene foam, i m sorry is plastic generally made that petroleum.

Styrofoam deserve to be uncovered in 2 versions: expanded and also extruded; and one the the main differences is that the extruded version is water-resistant, when the coercion one isn"t.

Another one is that the extruded form is a better insulator many thanks to its greater R-value than the worth of the intruded one.

Now, you might be wondering what the R-value is. The easiest means to define it is to use a definition by Wikipedia:

“In the context of building and construction, the R-value is a measure of exactly how well a two-dimensional barrier, such together a class of insulation, a home window or a complete wall or ceiling, resists the conductiveflow that heat.”

This way that if you great to have amazing insulation that is an alleged to have a higher R-value and the higher this value is, the reduced the amount of warm that go into/out of your house will be.

Also, that is necessary to recognize that friend can double the result of Styrofoam by including layers on top of every other and also that means their R-values get added and 2 times much less warmth is emitted or received.

For example, extruded Styrofoam has an R-5/inch value and the expanded R-4/inch. This is a much higher value than you would gain from loose-fill insulation, such as mineral wool.

So, Is Styrofoam a an excellent Insulator?

This material is exceptional for plenty of reasons:

it is rather lightweight and very easy come transport
it absorbs shock phenomenally and also is thus used because that packaging in numerous industries
it is offered as an insulator of course and likewise for creating various materials and also disposable packages
This is due to the fact that of its amazing trait and also it is the Styrofoam turns to liquid at a certain temperature and can be shaped easily.


It typically comes in white color and also is composed of numerous tiny balloon filled through air which enable it to work as a an excellent insulator. The air has actually a very little mass and also it is not sufficient to keep lot heat.

Because warmth is trapped in the air inside of these bubbles also means that conduction and convection cannot happen properly.

So there is some science and also the reason behind the good success the the Styrofoam.

So the answer to the key question is – YES, Styrofoam is an remarkable insulator.

Where is Styrofoam Insulation Used?

When we are talking about home insulation Styrofoam have the right to be used pretty much everywhere – ~ above roofs and floors, walls, in basements, attics, ~ above ceilings, together exterior insulation and likewise for acoustic insulation.

Not just that it is used for insulation in homes and also public structures but additionally is widely offered appliances, such as refrigerators, freezers and other industrial cold storages.


Another factor why the is so prevalent is the truth that it is water-resistant and also quite long lasting – once you download it you can rest assured that you"ll have actually quality insulation because that years come come.

In case you great to usage environmental-friendly materials, I have some great news, Styrofoam is again your selection since the is just that and also recyclable.

Perks of making use of Styrofoam because that Insulation

As already mentioned Styrofoam is your go-to material if you great to insulate any room and the factors why girlfriend should pick it space numerous:

Recyclable and environmental-friendly
Lightweight and easy come carry
Good quality insulator
Water and moisture resistant
Mechanical resistance – the is perfect for applications which be affected by each other a lot of of lots (i.e. Floors)
Durable – it has actually a life expectancy of about 50 years and also maintains its short conductivity

Styrofoam Alternatives

In situation you are looking for any other insulation alternatives here are some great alternatives you can think about.


This is one of the ideal “green” alternatives in instance if friend are searching for a product that is biodegradable and also renewable.

Its main element is developed from mushroom that room grown right into shapes that are fit for insulation and this happens thanks to a particular mixture of agricultural bio-waste.


Cellulose is additionally one of the ideal eco-friendly materials you might you because that insulation, also though the is not used that commonly.

Its main ingredients room cardboard, paper, and also several other materials. Similar to Styrofoam, it is additionally quite lightweight and also easy come carry.


Now, if you are looking for a “safe” choice and don’t wish to experiment much, then fiberglass could be her option, specifically if you are around to download it on loose walls.

This is the ideal option if your home, job-related area or any type of other an are is still under construction. You might do this yourself, or rental a company that will certainly install it for you.
