Applications of Building Insulation Products Based on Natural Wool and Hemp Fibers

FITNESs, Fibre Tessili Naturali per l'Edilizia Sostenibile (Natural Textile Fibers for Sustainable Building), is a research project concerning an experimental hemp and sheep wool insulation panel. The new panel has two main innovative features: unlike the already existing hemp and wool insulation mats, it is a semi-rigid product and has low environmental impact, as shown by the Life Cycle Assessment. FITNESs panels are particularly suitable for eco-building sector, as they are 100% natural, recyclable and made with by-products from local production chains (Piemonte Region). The paper presents the production process of the panel from wool and hemp fibers and some experimental applications for sustainable architecture.
