The environmentally friendly lead substitute from Leadax can be used like rolled lead and apart from the ecological aspect, offers installers other advantages too:
Unlike conventional wall-chimney flashings such as FLECK ECO FORM is made from recycled polyvinyl butyral (PVB). This is acquired from high-quality automotive laminated glass interlayer films in a special recycling method. Leadax, the manufacturer of the product, processes the raw material to produce FLECK ECO FORM. The expanded metal used is aluminium. By reusing the recycled raw material, a contribution is made to reducing global waste.
Furthermore, FLECK ECO FORM is UV-stable and very durable. It generally withstands exposure to the weather at least as long as all other materials on the building envelope. It can therefore remain on the roof for a number of decades without reservation. However, when the product does have to be replaced, Leadax can use the material to produce new FLECK ECO FORM EASY and ECO FORM MAX.
In February 2023, FLECK ECO FORM EASY was awarded the sustainability certificate by the Central Association of German Roofing (Zentralverband des Deutschen Dachdeckerhandwerks e. V. – ZVDH). Before the certification, FLECK ECO FORM EASY had to pass through an extensive test process, because to obtain the “sustainable product” marking, strict criteria regarding production, product properties and recyclability must be met. The assessment criteria of the ZVDH are based on the “Sustainable building rating system of the Federal Government” (BNB) in Germany as well as the state “Sustainable building quality seal” (QNG). With the new certificate, the ZVDH wants to show roofer firms and owners, in a simple way, which products are based on sustainable principles.
Thanks to the use of polyvinyl butyral (PVB), FLECK ECO FORM is 75 percent lighter than conventional lead, which makes it easier to apply. It can also be cut and moulded effortlessly. In addition, the Leadax lead substitute has high extensibility without forming cracks.
It is installed differently for each product:
The material can be moulded by hand or with the help of a dresser or roller.
