The Alliance for Sustainable Building Products (ASBP) launched a new industry briefing paper in August 2019, part of a series that aims at generating a greater understanding of the roles, capabilities and related issues concerning natural fibre insulation (NFI). In doing this, they hope to enable industry to deliver better buildings designed to take advantage of the significant building performance benefits of NFIs.

Airtightness, vapour control and breathability play a critical role in the operational performance of buildings. Understanding how they work together enables us to control air leakage, maximise energy efficiency, optimise indoor air quality and ensures durability of the building fabric.

The paper has been authored by Mark Lynn, ASBP Vice-Chair & Managing Director of Eden Renewables/Thermafleece, and peer reviewed by members of the ASBP’s Natural Fibre Insulation Group.
