Leadax Flashing | Lead Alternative

Leadax Flashing

LEADAX is the first lead substitute in the world that looks like lead, dresses like lead & is as malleable & pliable as lead. Leadax has the same unique properties as Lead & Zinc, without having to compromise on quality, flexibility or price. Leadax is applied in exactly the same way as Lead & is equivalent to code 5.

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 lighter than lead and produced from recycled materials.

Leadax is used and processed in exactly the same way as lead — without compromise.

Leadax - Lead Alternative

  • Leadax has the same natural look as traditional sheet lead.
  • Leadax leaves no staining on roof tiles or masonry.
  • Leadax has no resell value.
  • The life expectancy of Leadax is at least 30 years.
  • Leadax is a fully circular product.

This makes Leadax unique as a lead alternative and contributes to making the world more sustainable.

Leadax - Lead Alternative

Polyvinyl butyral (PVB) is the plastic foil in safety glass which could not be reused, until now. There is an abundance of PVB waste available worldwide. In Europe alone, 1.5 billion kilograms of PVB waste are added to this enormous pile of plastic waste. Every year. For comparison: This is the weight of 150 Eiffel towers. Besides that, current products for waterproofing buildings are not sustainable, have a large carbon footprint and are (often) toxic. If we want to reach the Sustainable Development Goals of the United Nations in creating a sustainable environment, this problem has to be solved.

Leadax Applications

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

Leadax Church Restoration

I would like to thank all at Leadax for a great product that has replaced the Lead that was stolen from our church roof recently. The product looks so similar to lead that you hardly notice the difference until you are up close. Once up close, you can see and feel the quality of the product.

Another great upside of using Leadax is that the product is much more sustainable than lead and also uses recycled materials to produce it, which is great knowing that we are playing our part in reducing our impact on the planet. We used a local company that specialises in using the Leadax products are pleased with the finished product. Once again thank you, Leadax, for a great product!

This online CPD presentation will develop your understanding of sustainable and circular lead replacements. It will discuss the reasons for developing a sustainable and circular lead replacement, the importance of the circular economy and using waste materials to prevent future waste, the applications and benefits of sustainable lead replacements, issue of lead theft, and how lead replacements can be used to combat this rising crime. By the end of the CPD you should have a greater understanding of:

  • How sustainable lead replacements benefit the environment, by utilising existing waste materials and creating a wider impact
  • How circular lead replacements and manufacturing processes can reduce the consumption of raw materials and material waste
  • How, why and when to use sustainable lead replacements
  • How to ensure that a high-performance sustainable lead replacement is used and what to look for and ask when specifying
  • How to reduce lead theft, particularly from churches by using lead replacements
  • Case studies which demonstrate the use of sustainable lead replacements in churches and listed buildings
