The new lead

Leadax is the first lead alternative in the world with the same properties as traditional lead. Leadax is not harmful to health or the environment. A new generation of lead alternative which is not only easier to use but also easier on your pocket. From cavity walls to chimneys, Leadax is used and processed in exactly the same way as lead — without compromise!


Leadax is cheaper to buy than traditional lead. And because Leadax is also faster to install, this leads to lower installation costs.

Light weight

Leadax is lighter than lead and therefore easier to use.


Unlike traditional water-resistant materials, Leadax does not contain any heavy metals.

Product features


Leadax has the same natural look as traditional sheet lead, however it leaves no staining on roof tiles or masonry. The life expectancy is at least 20 years.

Add colour to your design

Leadax comes in lead grey as standard. However the product is also available in black, roof tile red and different colours are available, such as copper.

Longer roll lengths

Leadax is available in longer strips. So you can seal larger areas with less overlap, saving you materials and time.


Leadax has been certified by BBA & KIWA.
