Leadax Original is our first-ever circular lead substitute, made from recycled polyvinyl butyral (PVB). PVB is the safety film used in laminated glass such as car windows. Unlike traditional waterproofing materials, Leadax Original is not a heavy metal. Therefore, our products have no harmful effects on your health or the environment.

After the expected lifetime of at least 30 years, the product is recycled. The raw materials are reused to make new products. Thus, no new raw materials need to be used and the circle is closed.

The light weight, but also the longer roll lengths, make Leadax Original easier and faster to process than traditional waterproofing products. You don’t have to make an overlap after every meter. In fact, thanks to the longer roll lengths, you can seal more in the same time with less overlap, making you more efficient with time and material. This makes the product not only better for your back, but also for your budget. Win-win.
