Book Description

This Information Paper provides a broad view of the benefits and limitations of natural fibre insulation for those considering its use in construction projects.

Natural fibre insulation covers a variety of insulation products that are derived from natural products such as wood fibre and cellulose, wool, hemp, cotton and flax. Natural fibre insulation products can often be used as replacements for mineral- or petrochemical-based insulation. When used appropriately, natural fibre insulation materials can deliver thermal and acoustic insulation comparable to other insulation materials, but with a lower or potentially negative carbon footprint and fewer health issues during installation. They can also assist in regulating relative humidity, and can provide a vapour-permeable system. This multi-functionality should be borne in mind when specifying natural fibre insulations in order to ensure maximum value and benefits.

This is one in a series of five Information Papers and parallel case studies on low-impact building materials. The others cover hemp lime, straw bale, unfired clay masonry and cross-laminated timber.
