Leadax - New Alternative to LeadLeadax 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!


Cheaper ... cheaper to buy than traditional lead, and because it is also faster to install it benefits from cheaper installation costs.

Lightweight ... lighter than lead and therefore easier to use.

Circular ... a fully circular product, which makes it a unique alternative to traditional lead and contributes to making the world more sustainable.  The basic raw material is recycled PVB. PVB is the foil that is used in laminated glass (e.g. car windows or safety glass).

Durable ... 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 30 years.

Certified ... Leadax has been certified by BBA & KIWA.

Material ... Aluminium expanded metal on both sides with a layer of modified polyvinyl butyral, with a removable protective film on either side of the product. Leadax is patented.

Leadax is ideal for use as a prefab element. It reduces the time required for installation and manufacturing, and there is no risk of construction errors.
