Why choose Leadax?

Leadax Original combines the familiar look and feel of lead sheet with a lightweight, flexible material made using recycled PVB. Shape and dress it using techniques you already know. Create watertight connections on and around the roof with lead-free flashing designed for everyday work.

01

Smarter

Six-metre rolls let you complete longer runs in one piece. Fewer overlaps mean fewer installation steps and less material used at each joint.

02

Safer

Leadax Original is lead-free and weighs 3.85 kg/m². Its low weight makes it easy to lift, carry and shape into place.

03

Cleaner

We use recycled PVB from laminated safety glass as a raw material. This gives an existing material stream a new purpose in construction.

Versatile applications

For the work you already know

Leadax Original is suitable for Code 5 lead sheet applications, creating water barriers in cavity walls and above and below window frames, as well as watertight connections around chimneys, dormers, roof windows, extensions, valleys and ridges. It is also suitable for detailing around in-roof solar panels, heat pumps and roof penetrations.

Valleys

For a watertight seal in valleys and at the ridge.

Chimneys

For connections to roof tiles and stepped flashing details.

Dormers

For connections at dormers, roof windows and cheeks.

Extensions

For watertight connections between an external wall and an extension, using apron flashings and/or cavity trays.

Developed for professionals

More metres. Less strain.

Leadax Original uses familiar installation techniques, yet weighs considerably less than traditional lead sheet. Rolls up to six metres long reduce overlaps and help save time and material.

Lightweight

Less physical strain during transport and installation

Flexible material

Easy to shape around different details

Long rolls

Cover more with fewer overlaps

No scrap value

A less attractive target for theft
