Safer insulation

Instead of the types of insulation mentioned in our other sections and those types which can emit toxins, it is better to use things such as cellulose fibre or, even better, cork. Even so, you should still check that these alternatives are not coated in conflicting plastics (instead: use a natural varnish) and you should use natural adhesives e.g. lignin glue to attach it. Clay, straw, fleece, bio-cement or expanded clay are other possible alternatives.
