Welcome to SisalTech

Healthy and Sustainable Insulation 100% Natural


Our sisal is sourced from small-scale farmers in east Africa and we ensure they are paid a fair price. At Eco-Build 2018 we committed to assessing how we contribute to the Sustainable Development Goals and since then we have examined what we can change to further contribute to nine of the goals. These include No Poverty, Good Health and Wellbeing, and Responsible Consumption and Production.


Sisal plants are grown organically and the same plants can be harvested for up to thirty years. The sisal fibre is sun-dried and no water is required in the processing. Although our fibre is shipped all the way from Africa the end product still has a significantly lower carbon footprint than any of our mainstream competitors.


Unlike other insulation products, sisal can be handled safely without protective clothing and has no carcinogens. It does not off-gas so is safe to use even in very airtight homes.


Sisal is used for making a wide range of products from coffee sacks to ships ropes but we are the first company to innovate with sisal’s thermal performance.

Why Sisal?

Sisal is a highly sustainable fibre crop which is grown organically.

It has a very low water demand, and so can help farmers in Africa cope with the impact of climate change. Sisal was historically used for making ropes and sacks, however during our research and development phase we discovered that it has excellent thermal properties, making in an ideal fibre for use in insulation products.
