Green Insulation Is Critical To The Clean Energy Revolution

The Environmental Protection Agency (EPA) estimates that homes and commercial buildings emit more than 13% of US pollution. Though that might seem smaller than electricity production and transportation, they still pose a unique challenge to climate change.

As the clean energy revolution continues in the U.S. and worldwide, many people are desperate to protect planet earth. One of the best ways to ensure buildings are sustainable and energy-efficient is by embracing green insulation.

That’s why we’re sharing extensive information about green insulation, its benefits, and more! We’re here to help you understand what green insulation is and how it is critical to the clean energy revolution.

Why does the clean energy revolution matter today?

All countries across the globe are putting an emphasis on green energy solutions. Businesses and large-scale companies are investing more in clean energy technologies to help tackle climate change. Every nation understands its future to be clean energy, and America is no exception.

Sustainability plays a vital role in society. People are ready to enjoy their lifestyle more consciously, wanting to feel secure that it doesn’t hurt the environment. Although switching to clean energy isn’t a walk in the park, the extended benefits are worth it!

The U.S. national power grid has set aside $73 billion to boost clean energy investment in businesses and homes. Apart from financial aid, the government has also set fiscal measures to invigorate investment in green insulation, including concessionary loans to homeowners. All these are geared towards saving and protecting the environment.

Why is green insulation important?

You don’t need a degree in thermodynamics to know why green insulation is necessary. Here’s the simple explanation: Heat travels from highly concentrated regions to low-concentrated areas, meaning that air from your residence can rise and dissipate into low-temperature areas. Insulation can help prevent air exits and keep your home cooler in summer. In short: Good insulation keeps the air at the temperature you want (cold or warm, depending on the season) and keeps it in your home, no matter the outside temperature.

Improper insulation is costly as homeowners will spend more on cooling and heating. Green insulation is crucial because it eliminates emissions during production and lowers energy costs once in use.

The U.S. Dept. of Energy shared that 44% of the energy used in homes is for heating and cooling. Insulation is one of the essential factors contributing to home energy efficiency and can help cut down on such energy use.

How green insulation works

The concept of how green insulation works involves three basic mechanisms: radiation, conduction, and convection. Radiation is the way heat travels in a straight line. Conduction consists of the movement of heat through materials. And convection involves heat movement through liquids and gases.

Many insulation materials work by reducing conductive and convective heat flows. But reflective and radiant insulations work by slowing radiant heat gain.

Measurements used to determine insulation

The effectiveness of insulation is measured by the thermal resistance value, best known as R-value. This resistance value is estimated between 1 and 60. The higher the R-value, the better resistance. The following factors can determine the thermal resistance value;

  • Air density
  • The thickness of the insulation material
  • The location where you install the insulation
  • The type of insulation

There’s also something called standard insulation that’s determined by the:

  • The climate around your area of residence
  • Your home location
  • The heating and cooling system type

Best green insulation options to consider

When it comes to green insulation, you can use various options. Despite their difference in effectiveness, most of the green insulations covered here perform well. Here are the top-rated options available right now.

Wool insulation

You may have heard of sheep’s wool in clothing manufacturing, but did you know wool can be used in wall and ceiling insulation? Yes, the plush material can work as a fire-resistant material in your home!

Regarding thermal conductivity, sheep’s wool offers an extra benefit over other insulation materials. It can neutralize air pollutants, thus improving your indoor air quality. The wool is typically combined with 20% polyester to ensure optimal strength. And because it is natural and not factory-made, this material is sustainable and renewable.


Although aerogel doesn’t occur naturally, it doesn’t necessarily mean it is not eco-friendly. If you are thinking of insulating your home with aerogel, it’s a good idea. Many homeowners are already using this material.

Aerogel’s production mainly involves silica. But it also contains other materials like copper, iron oxide, gold, and other organic polymers to ensure better performance. Aerogel can prevent moisture damage and corrosion thanks to its water-repelling capabilities.

Icynene spray foam

This type of insulation uses zero-ozone-depleting agents. It is perfectly designed with every homeowner in mind. It doesn’t emit any volatile organic compounds. In fact, icynene is made of recycled materials with no harmful chemicals.

Icynene is resistant to water. So, it can help enhance the level of moisture within your home. It can also help improve air quality by creating a solid air barrier against pollutants, dust, and pollens. This can be an excellent choice for those who have asthma, allergies, or sensitivity to chemicals.


Cellulose is another popular and commonly used insulation material for walls. It is mainly manufactured using recycled denim, which makes it highly biodegradable and environmentally friendly. Today’s cellulose is even treated with non-toxic chemicals to protect your home against mold buildup.

However, cellulose is somewhat sensitive to moisture. This is one weakness that sometimes affects its insulating properties. Cellulose might not be the best solution, at least on its own, for those living in humid regions. However, there are other products like vapor and moisture barriers that can help protect this insulation from moisture damage.


Fiberglass is best known for its lightweight and durability. It is engineered using glass fibers to control and insulate sound and heat transmission effectively.

Fiberglass is fire-resistant and can be pressed into place. Research shows that fiberglass can reduce energy costs by 40%. While getting in contact with its particles can cause irritation, adequately installed fiberglass can provide a cost-effective solution to insulation problems.


Cork is manufactured using cork granules. It is 100% natural. Cork has a negative carbon footprint, which is why it is considered the most environmentally friendly material.

Besides insulating your home, cork can help protect against mold buildup. It can also help prevent the development of moisture. Additionally, cork is durable and can serve you for many years. Though it is relatively expensive, the benefits are worth it.


Denim, also known as cotton, is naturally pure and can be used to insulate your house. Cotton insulation is treated with borates, which makes it more resistant to pests. It doesn’t cause any respiratory issues, it is easy to install, and it is also fire-resistant. Check, check, check!

Other advantages of using denim insulation include a high R-value, which makes it an excellent choice when it comes to retaining heat and even soundproofing. Plus, denim insulation might be the best option to keep bugs out of your home.


Polystyrene is best known for its use in manufacturing plastic toys. But in its expanded form, polystyrene can make ideal home insulation. It contains many small pockets of air, making it heat resistant.

Also, it is lined with aluminum foil to help it prevent radiant heat. It doesn’t irritate the human skin. It is also odorless and eco-friendly. This insulator has the best R-value rating.
