It is a chemical free product

One of the reasons it has gained so much traction is because the product does not contain any chemicals. Cellulose fiber is a well known product that contains chemicals. Both isotherm and cellulose fiber hold around the same r-value. So why not use the product that is chemical free?

It is a fiberglass free product

Another very popular product would be aerolite insulation. It has been around for over 75 years already. It has become a household name over the years.
