Although it was an incredible solution and worked well to resist heat and corrosion, it turned out to be deadly for people that breathed in its particles. Cellulose insulation is an alternative to asbestos. It has many of the same characteristics as far as performance, but it is made up of harmless materials such as hemp, cardboard, and straw. Cellulose insulation is widely used today and comes in many forms.If you suspect that you have asbestos insulation in your home or business it is best to call a professional that can test the source and help you to safely remove any harmful materials if they are present.
