When considering how to specify an insulation material in terms of environmental impact, it is often the case that the 'natural' material is the most beneficial in terms of environmental attributes.

materials,2) polymeric insulating materials offer processing advantages such as low cost, light weight and low-temper-ature processing by spin-coating or ink-jet printing. Addi-tionally, these materials present the unique possibilities of tuning their electrical, optical, thermal and mechanical properties through subtle modifications of their Cited by: Fire resistant and acoustic insulation.

In many situations the thermal insulation may also serve as fire resistance and acoustic insulation. This is often a complicated matter which is dictated by the building regulations. Suffice to say that if you want to alter the type of insulation from that shown on the drawings which have received building regulations approval then you will probably need.
