Using today's waste to prevent global waste forever. With our circular and sustainable waterproofing building materials we are on a mission to change the world for the better. Our current product is Leadax flashing and in 2020 we will introduce Leadax roofing. The raw material of our products is polyvinyl butyral (PVB), which is used in laminated glass, such as safety glass in car windows. By using this raw material we not only want to reduce the >1 billion kg's of waste it represents, but we also aim to create products which are better and more sustainable than its counterparts. At the end of our products' life-cycle they can be recycled and reused as Leadax again. In short, we are closing the loop.
