What drives us
Our business model is agile, independent, and fully transparent in terms of material- and kitting costs, which allow our clients to make the right decisions regarding sub-suppliers, core materials, specifications, and requirements. No matter the specific need, our engineers are ready to go through the iterations of prototyping and testing necessary to deliver a quality kit.
For us, a core kit is not just yet another component - it is what we do and what we know. For more than 30 years we have been supplying core kits to the industry, which has allowed us to effectively adapt every single part of the involved processes to maximise the output.
From our custom machinery to the location of our production and storage facilities, we empower performance – of material, of kits, of turbines, and of the industry. By choosing JSB as your kitting partner, you get a global ally driven by continuous improvement, flexibility, and transparency.
Your global core kit partner
Our production sites are placed strategically at the centre of several wind blade production clusters. Our global sites are in constant dialogue with each other through weekly meetings and a constant eye on performance indicators and best practices. We do this to ensure that all of our products adhere to our own high standards.

Meet the management
Developing from a one-man operation to a 470+ one has been an exciting journey, and has shaped a humble yet passionate culture that we are proud of. At JSB, we are a diverse, international group of people with vastly different backgrounds, areas of expertise, and daily responsibilities.
What we have in common, however, is a passion for empowering our clients’ performance through the products and services that we provide. We know that the success of JSB, historically and in the future, is a result of an inclusive and supportive environment that disregards national borders, job descriptions, and whether your daily job places you at a desk, on the road, or in the production hall.
Our management team draws their knowledge from vast experience of working in the industry. Each core kitting project is handled by a dedicated business manager within our company.
