• From cavity walls to chimneys, Leadax is applied in exactly the same way as lead.
• Leadax is cheaper to buy than traditional lead. And because Leadax is also faster to install, this leads to lower installation costs.
• Leadax is lighter than lead and therefore easier to use.
• Unlike traditional water-resistant materials, Leadax does not contain any heavy metals.
• Leadax is available in longer strips. So you can seal larger areas with less overlap, saving you materials and time.
• The basic raw material is recycled PVB. PVB is the foil that is used in laminated glass (e.g. car windows or safety glass).

What makes Leadax Original unique?

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 about 50 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.

Common applications

• Leadax Original can be used as a water barrier in (cavity) walls and under casings.
• At the intersection between chimney bases and roof tiles.
• At chimney flashings to provide a water barrier.
• Leadax Original can be applied to the base of dormers and skylights as a waterproofing layer.
• As a watertight connection between an outside wall and an extension. Use Leadax masonry clips to attach Leadax Original to masonry joints.
• Leadax Original can be used as valley gutters and waterproofing on the ridges of (tiled) roofs.
