Sisalwool - part of Sisaltech Ltd, a Certified B Corp™ company profile

Sisalwool (a trading name of Sisaltech Ltd) makes high-performance natural fibre insulation designed to be better for buildings, people and the planet. Our semi-rigid batts and loft rolls are vapour-open for healthier, moisture-regulated homes, installer-friendly to handle and fit, and deliver proven acoustic comfort (up to Class A sound absorption) alongside strong thermal performance. We prioritise circular inputs — blending sisal and sheep’s wool with recycled fibres — including used coffee sacks from UK roasters and textile offcuts, and we operate return-for-recycling at end of life. As a Certified B Corporation, we’re part of a global community of businesses meeting high standards of social and environmental impact and committed to continuous improvement. Founded in Scotland, we support retrofit and new-build projects across the UK with practical guidance and specification resources.
