What is the most eco wall insulation matirial?

Eco wall insulation is done because it saves energy and it is green in nature. Most of the people think that,It will remain green if it contains a high percentage of recycled materials.While for others,it is green if it doesn't contain any harmful substances which can cause health problems.But still there are many who agree that it is green just because it is made up of natural materials.Material which is loose and which comes in rolls, like cellulose and glass wool, is used in lofts and flat area in order to get the eco insulated walls.Recently I have done eco wall insulation with the help of Atlantic Ocean Group.They provide all house repair services at garage door repair Davie including wall insulation.Know more about them at atlanticoceangrp.com .
