Insulation is essential for residential and commercial properties alike. It helps regulate your indoor temperatures and acts as a barrier to prevent cooling and heating from escaping your space when correctly done. As a result, your property becomes comfortable, which automatically boosts productivity.

But still, unless you are an insulation expert, it can be challenging to understand everything needed to make the process effortless and highly beneficial. And, to avoid confusion, learn from the industry experts such as those from With the help of insulation professionals like these, you will better understand many things, such as attic insulation, wall insulation, and even radiant barrier insulation. Next, let’s explore more about insulation and the cheapest way to do it.

The Available Ways to Do Insulation and Choosing the Cheapest

The idea of finding the most affordable way to do insulation comes from the types of insulating materials and the process involved in using those materials. And because they are varying types of insulating materials, let’s take a look at each of these materials to help decide the cheapest based on your budget and preferences.


Fiberglass is among the standard types of insulation you will come across in many homes. And unlike its counterparts, fiberglass insulation uses tiny and thin strands of glass woven materials. However, if you want an environmentally-friendly insulation option, fiberglass is not the best option because it has a low-R value. But still, unlike others, fiberglass insulation is the most affordable and cheapest way overall.

The Mineral Wool Insulation

Mineral wool insulation is made of various recycled materials and is a better option if you want a naturally fire-resistant insulating option. Mineral wool insulation works better with the help of cotton and animal wools such as sheep’s wool which you can use to insulate your walls and ceilings. Plus, cotton and sheep’s wool contain high R-values, which means they can even double the advantages of insulating your space the same way an acoustic insulator works.

At the same time, mineral wool insulation is a better option because sheep’s wool purifies the air by eliminating harmful contents. And as the wool purifies these toxic substances, it turns them into fibers which render them safer. 

On top of that, the wool regulates humidity by absorbing moisture within and around your space without getting damp. Plus, as it does this, the wool remains in excellent condition, meaning you can effortlessly recycle and reuse it repeatedly.

Denim Insulation

Denim insulation also comes from recycled and sustainable materials. Because of these features, the insulation requires less energy to make it eco-friendly as it cools and heats your space. Plus, like wool insulation, denim also doesn’t contain harmful substances making it a safer insulating option. And more importantly, denim insulation cools and heats your place and helps keep away pests because it smells natural and repels insects.

Spray Insulation

As the name implies, this type of insulation involves spraying instead of rolling and stuffing blankets or other insulating materials. For this type of insulation to work, spray onto the areas you want to insulate and leave them for some time to cool and heal. The process also involves various ways and materials such as soy, cellulose, Icynene, and polystyrene.

Icynene Spray Insulation

For Icynene, this spray insulating material comes from castor oil, and you use it to spray the area you want to insulate as the oil produces foam that expands onto surfaces.  And unlike its counterparts, Icynene spray insulation is a perfect option for insulating sealing leaks and even drafts. 

Soy and Cellulose Spray Insulation

Soy-based insulation always works best when combined with cellulose. And as these two combine, they form a more environmentally-friendly insulation option than Icynene. Plus, soy-based insulation also comes in foams that expand as you spray them onto surfaces. In addition, the combination of these two materials form mold, moisture, and fire-resistant insulators. 

Polystyrene Insulation

The reason why this type of insulation isn’t popular is because of its limited environmentally-friendly advantage. And this factor is because polystyrene comes from plastic materials and has an extremely high R-value. But due to its high R-value characteristic, polystyrene insulation saves more energy making it one of the most affordable options.

ThermaCork and Aerogel Insulation

ThermaCork comes from the bark of oak trees and contains some carbon footprints. As a result, this type of insulation is renewable and recyclable. Plus, it works as a noise canceler. For Aerogel, this one is more costly and works best if you want to insulate an extremely hot space.
