Leadax

Polyvinyl butyral (PVB) is the plastic foil in safety glass which could not be reused, until now. There is an abundance of PVB available worldwide. In Europe alone, this pile of waste weighs in at more than 1.5 billion kilograms (each 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.

Applications

Valley application


Leadax lead replacement is a perfect alternative to the zinc valley. One of the benefits Leadax lead replacement has over using zinc is that our product does not have to be formed in the workshop, but can be applied right on the job. This saves time and man-hours. In addition, our lead replacement can be applied in roll lengths of 6 metres. Also, it does not respond to changes in temperature. Even after many years it will not show any cracks on the surface. Since our lead replacement has the look-and-feel of traditional lead it is also suitable for the renovation of heritage buildings. 

Cavity wall


A cavity wall is a place where you'd normally find a lot of lead. However, when you apply lead, you have to create an overlap after every metre, since it'd crack due to temperature changes otherwise. As you can see in the video, Leadax lead replacement is applied in the same manner as lead. This means that the end user does not experience anything different, other than that it's much easier to apply our lead replacement than lead. 

Dormer application


Leadax lead replacement can either be applied directly on the roof, or pre-installed in the workshop, depending on your personal preference. Our lead replacement is available in lead grey, black and terracotta, so it always matches your roof and dormer. Leadax lead replacement is just as robust as lead, so there's no risk involved of the product being affected by the wind. Just to be sure we do advise to use a Hybrid Polymer Sealant to adhere the lead replacement to the roof tiles.

Chimney application


Since Leadax lead replacement has so many uses, it's also perfectly suitable to replace lead in chimney applications. Our lead replacement is applied the same way as lead, including soakers and step flashing. The result is a chimney with a lead replacement, that's indistinguishable from lead at first sight. Moreover, our lead replacement has expanded metal, which makes it easy to trim it to the right size.
