Unlike traditional water-resistant materials, Leadax’ products do not contain any heavy metals. In addition, Leadax is available in longer strips. So you can seal larger areas with less overlap, saving you materials and time.
What is PVB?Â
Polyvinyl butyral (PVB) is the plastic foil in safety glass that could not be reused until now. There is an abundance of PVB available worldwide. In Europe alone, this waste pile weighs in at more than 1.5 billion kilograms (each year!). For comparison: This is the weight of 150 Eiffel towers. Besides that, contemporary products for waterproofing buildings are not sustainable, have a large carbon footprint and are (often) toxic.
Using Leadax

Leadax can be applied to the base of dormers and skylights as a waterproofing layer and at the joint between dormer side walls and tiled roofs.
