Styrofoam is a good insulator; it cuts down on heat loss through the walls and ceilings of your home. You can use styrofoam to fill in spaces between studs or joists for insulation, as well as to seal up any cracks in the surface of exterior walls. Styrofoam is rated R-3 per inch, which means that one inch of styrofoam provides an equivalent level of insulation that three inches of fiberglass would provide.
The downside to using this material for insulation purposes is that it has a high rate of moisture absorption over time, and will eventually degrade and crumble if not properly taken care of (i.e., by adding a coat or two every year).
For this reason, many homeowners prefer to use more traditional insulation materials like fiberglass, rock wool or cellulose instead.
Styrofoam is one of the most environmentally friendly types of insulation on the market today because it does not contain formaldehyde and is made primarily from the air (carbon dioxide) and water vapor, with some added chemicals. It’s also lightweight which means that it can be installed in areas where heavy bags of other products cannot go – such as up high near roof rafters for example.
The main drawback when compared with other insulation products however is that styrofoam loses its insulating abilities over time if exposed to constant moisture.
This makes it less than ideal for colder climates where there tends to be a lot of snow during the winter months.
In these climates, it’s best to choose a different type of insulation that will remain permanently dry and maintain its temperature-reducing properties over time.
How does Styrofoam insulate
When we think of insulation, Styrofoam probably isn’t the first material that comes to mind. But this cheap and easy-to-find substance has been used for decades in construction projects.
Mainly because it’s effective at preventing heat transfer from one area within a building while also being lightweight enough so as not negatively impact the structural integrity or pose safety risks.
Air as an Insulator
Inside each air pocket, there are millions of little pockets full of tiny bubbles tightly packed together – these spaces between molecules allow them all to hold their own gas effortlessly without letting any escape before another joins up on top.
This is what allows air to insulate and also why Styrofoam does such an amazing job at holding in the heat or cold. It also does well with sound waves and vibrations which all require a certain amount of kinetic energy (moving molecules) to be emitted from one side so they can reach you on another.
Alternative materials that are good for Insulation
Insulation is an important part of any home, and it’s something that homeowners should consider. There are many different types of insulation materials available to use in order to make your home more energy-efficient.
Some people may not know what the difference between various types of insulation is or why they would choose one over another.
While fiberglass is the traditional go-to, there are a number of alternative options that are better for both you and the environment.
One option is to cover part or all of your walls with straw bales. Straw has insulating properties similar to fiberglass but it also captures moisture which causes mould in homes. It’s an excellent way to stop air leaks while increasing thermal mass in your home by storing heat from day till night.
You can also use wool blankets or sheepskin rugs if you don’t want something permanent like straw bales. The natural fibers will keep drafts out much more effectively than synthetic materials like fleece or cotton.
Natural materials like these are beneficial for you and the environment in a number of ways.
