Sisalwool Natural Fibre Insulation

We combine sisal plant fibres with wool or cotton - often using old sisal coffee sacks and offcuts of wool and cotton - to produce high-performance insulation, helping to reduce landfill waste while delivering exceptional warmth, soundproofing, and breathability. Our eco-friendly insulation is damp proof, fire-treated and non-toxic - meaning no itchy skin or burning eyes.
