Circular waterproofing products for the world of today

Thousands of professionals worldwide of all sizes – from small businesses to large enterprises – use our sustainable, circular & award-winning flashing and flat roofing membrane to waterproof their buildings.

With our circular and sustainable waterproofing building materials, such as ‘the new lead’ and PVB Roov, we are on a mission to change the world for the better. We use PVB waste as raw material and at the end of our products’ life-cycle they can be recycled and reused as Leadax again. In short, we are closing the loop.

Leadax PVB Roov is the new and fifth standard in flat roofing. This is by far world’s most sustainable flat roofing with an extreme low carbon footprint. Besides this, the membrane is white which makes it highly reflective and it is also easy to install without fire.

In the Leadax product range of flashings, there are two types of circular and sustainable flashings in the Leadax product range. The first is the ‘Original’ which is the first lead replacement with the same look and feel as toxic lead. The ‘Easy’ is the second kind of flashing and is with an adhesive. Installers around the globe like to work with both.
