Cellulose loft insulation

Cellulose loft insulation is a fluffy material made of finely shredded recycled newspaper. With added fire retardant and biocidal additives, it is non-toxic, not attractive to vermin, doesn't rot, and requires little energy to produce. Issues may arise if it gets soaked - it could release printing ink smells or loses it fire retardant qualities. It is safe to handle and can be spread between and above loft joists without any negative effects on PVC covered electrical wiring. Paper can also be made into board form with the addition of recycled jute sacking. It may be treated with borax for resistance to fire and rot. Brands include Excel Warmcel and Homatherm board.
