We’re officially part of a Certified B Corporation™
In October 2025, our parent company, Sisaltech Ltd, became a Certified B Corporation™ – joining a global movement of businesses that meet the highest standards of social and environmental impact. For us at Sisalwool, this certification is more than a badge. It’s a reflection of how we already work – and a promise to keep doing better.
What B Corp certification means
Certified B Corporations™ are companies that balance purpose and profit. They’re assessed on how their decisions impact their workers, customers, suppliers, community, and the environment. It’s not an easy process — it looks closely at every part of a business, from governance and transparency to energy use and employment practices. For Sisaltech Ltd, achieving B Corp certification shows that our commitment to sustainability and social responsibility isn’t just talk. It’s embedded in our operations, our products, and our people.
How we performed
In our B Impact Assessment, Sisaltech scored strongest in the following areas:
- Environment: recognising our focus on sustainable materials, circularity, and reducing embodied carbon.
- Workers: reflecting how we support fair, safe, and engaging working conditions for everyone involved in our supply chain.
- Governance: acknowledging our transparent, purpose-led management and ethical decision-making.
Our scores put us well above the average score for our sector and size — a milestone we’re incredibly proud of.
Why it matters
From the very beginning, our foundations were built on tackling climate change and doing business responsibly. B Corp certification reinforces what we’ve always believed: that profitability and positive impact should go hand in hand.
It’s proof that we’re putting our money where our mouth is — continually improving how we work for the good of our customers, our people, and the planet.
What’s next
Certification isn’t the finish line; it’s a framework for progress. Every three years, B Corps are reassessed — and we’ll keep working to raise our impact across every area of the business. You’ll see more from us in the months ahead as we share our goals, our progress, and the steps we’re taking to make natural fibre insulation as good for the planet as it is for the buildings it protects.
