Does Styrofoam prevent heat loss?

Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can't flow through them. The same idea is used to keep the inside of buildings warm.

In Antarctica, winter temperatures can vary from -70ºC to -15ºC – it is one of the coldest places to live on earth. To survive in the Antarctic, keeping warm becomes a very important focus, and insulation is a major factor in achieving this.

Heat loss

Heat is lost in one of three ways – in each situation, heat moves from a hotter object to a colder one: Conduction – the transfer of energy in a solid object from one end of the substance to the other by the rapid vibration of atoms. Convection – the transfer of heat energy through a liquid or gas by the movement of the fluid (atoms or molecules). This movement, caused by the expansion of the fluid, produces a current as its temperature rises, called convection current. as its temperature rises, called convection current. Radiation – the emission of any rays, wave motion or particles from a source, most commonly applied to emission of electromagnetic radiation. Keeping warm involves stopping the transfer of heat from one object to another. This can be done by insulating the object.

Substances can either be conductors or insulators of energy:

Conductors allow energy to flow through them – metals are examples of good conductors. Insulators stop the flow of energy through them –substances like plastics, glass and air are good insulators.

Different methods of insulation

Keeping the inside of buildings warm and people warm can be done by covering them or any other object in layers of an insulator. Trapping air in layers is a very effective way of insulating an object. Cats fluff up their fur and birds do the same to their feathers when it is cold. This traps air inside the fur or feathers and reduces the amount of heat energy these animals lose. People wrap themselves in layers of clothes for the same reason. The thicker the layers and the more layers of clothing someone is wearing, the better the insulation. Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can’t flow through them. The same idea is used to keep the inside of buildings warm. Insulators like fibreglass and plastic foam are put into the cavity in the walls of a building to trap air and to reduce the transfer of heat energy so that heat stays inside the building. Another example of insulation is double glazing. In this case, windows are made with two layers of glass, with a layer of air trapped between them. This stops the movement of air in the space between the two layers of glass and reduces heat loss from the window.

Can you use newspaper instead of bubble wrap?

If you don't want to spend money on packing paper, you can use old newspaper as long as you double-up your fragile items. Newspaper is thinner than most packing papers. Also, be aware of ink!

To pay for packing services or to not pay for packing services—that is the question. Here’s another: Do you want to have to replace a broken dish set or risk chipping your precious china while it’s in the back of your moving van?

Broken household goods are top of the list when it comes to moving stressors. You have two packing options to avoid this calamity: hire professional packers, either through your moving company or a third-party packing service, or do it yourself. Of course, a moving company or packing service can be pricey. So if you’re more DIY-inclined (and your budget can’t handle the cost of replacing a bunch of broken items) but aren’t sure how to pack your stuff safely, we’ve got your back.
