Building contractors

Leadax meets all the requirements that you need as a construction professional.
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.

Circular material

The basic raw material is recycled PVB. PVB is the foil that is used in laminated glass (e.g. car windows or safety glass).

Longer roll lengths

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

A non-toxic and sustainable product

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

Light weight

Leadax is lighter than lead and therefore easier to use.
