A different way to think about waste. A practical way to build for tomorrow.
We turn recycled PVB from safety glass into waterproofing products for the building industry.
Every roof detail starts with a material choice. At Leadax, we ask how that choice can combine practical performance with a more thoughtful use of resources.
Our mission is to use today’s waste to prevent future waste. It shapes the materials we develop and the questions we keep asking: where does a product come from, how does it work on site, and what could happen to it next?
Research began into a recyclable raw material for an alternative to lead flashing.
Following development and testing, Leadax launched Original, made using recycled PVB.
The range has expanded to include self-adhesive flashing and roofing membranes. The ambition stays the same: give valuable materials a new purpose.
Founder Roeland van Delden brought experience in waterproofing to a new challenge: moving beyond a linear model of making, using and discarding materials.
That challenge became Leadax. Today, we work with partners to bring the idea into everyday construction.
