Find out in the next three the main advantages of using cotton wool in your future insulation projects.

What are the benefits of using cotton wool?

Among the advantages of this insulation can be noted:

A higher R value

R-Value is the term we use to refer to the material’s resistance to heat flow ; materials with higher R-values ​​are better insulators.
The R-value of batt insulation is comparable to fiberglass (the most common and least environmentally friendly insulation material). Cotton with good treatment can serve as an alternative to fiberglass without having to make major changes to the building plans.

However, keep in mind that it is best to hire a professional for installation. Although batt has a reputation for being easy to install, trying to install batt insulation without the help of a professional can lead to problems that later affect the insulation’s R-value.


It is safe to use cotton wool as insulation. You should know that cotton wool:

  • does not contain formaldehyde;
  • is treated with non-toxic boric acid;
  • does not cause allergies or respiratory problems and does not emit toxic fumes during installation or curing.

In addition, insulation wool can improve the structural integrity of your building because of its density. The density of cotton wool also allows it to better fill wall cavities and hold more oxygen. Less oxygen in wall cavities reduces the risk of fire spreading.


One of the main advantages of using wool as insulation is its environmental friendliness. Its production requires much less energy than most other insulating materials. In addition, the wool used for insulation is a highly renewable resource, made from recycled materials and obtained from plants that grow in nature.

Why use cotton wool?

The plant from which cotton wool is made is a renewable resource, making cotton wool one of the most sustainable insulation materials. Its ability to retain heat is similar to that of fiberglass. Unlike the latter, it does not contain formaldehyde (a substance that causes cancer).

Many people believe that cotton wool is better than other insulating materials. Natural heat-insulating materials have their advantages:

  • they have little impact on the environment and their production requires little energy;
  • they are biodegradable;
  • they are not toxic;
  • they regulate humidity and reduce the formation of condensate;
  • they give the pieces of wood additional protection against moisture,

While the cost of natural insulation materials can put off home owners, builders and developers, many believe they are worth the investment because not only do they have a low impact on the environment, but they can allow you to save money.Indeed, you will no longer need to use heaters (no more long-term electricity bills).

How much does cotton wool cost?

Cotton wool is expensive twice as expensive as fiberglassbut many homeowners choose batt insulation because of its ability to retain heat and its low environmental impact.
